Introduction

Metered dose inhaler MDI is a widely used handheld clinical device designed to deliver a measured amount of medication to the lungs as an aerosol. In hospitals and clinics, it sits at the intersection of medication administration and medical equipment management: it is both a drug-delivery platform and a workflow-critical tool that must be used correctly to be effective and safe.

For hospital administrators, clinicians, biomedical engineers, and procurement teams, Metered dose inhaler MDI matters because outcomes depend heavily on technique, product standardization, supply continuity, and infection control. It also has a unique procurement profile compared with other hospital equipment because it is commonly supplied as a drug–device combination product, and responsibilities may span pharmacy, nursing, respiratory therapy, and clinical engineering.

This article provides practical, non-prescriptive guidance on what Metered dose inhaler MDI is, where it is used, how it is typically operated, how to reduce safety and contamination risks, what “outputs” it provides (such as dose counters), what to do when problems occur, and how the global market and supply ecosystem typically looks across major countries.

What is Metered dose inhaler MDI and why do we use it?

Clear definition and purpose

Metered dose inhaler MDI is a pressurized, handheld medical device that delivers medication in discrete, metered actuations (“puffs”). Most commonly, it consists of:

A pressurized canister containing medication and propellant
A metering valve that measures a consistent volume per actuation
An actuator (plastic housing with a nozzle) that shapes the aerosol plume
A mouthpiece cap to reduce contamination and debris ingress
In some products, an integrated dose counter (varies by manufacturer)

The purpose is simple: enable rapid, portable, repeatable delivery of inhaled medication without the set-up complexity of many powered aerosol systems. From a hospital operations perspective, Metered dose inhaler MDI is valued because it can be deployed at the bedside, in ambulatory settings, and in time-sensitive clinical scenarios—provided staff and patients can use it correctly.

Common clinical settings

Metered dose inhaler MDI may be encountered in a broad range of care environments:

Emergency departments and urgent care, where rapid bronchodilator delivery is often part of acute respiratory management
Inpatient wards, including medical, surgical, and pediatric units
Outpatient clinics, including pulmonary and primary care settings
Operating room and perioperative areas, depending on patient pathways and medication formularies
ICU/critical care, including use with appropriate in-line adapters for ventilated patients (device approach and compatibility vary by manufacturer and facility protocol)
Ambulance/prehospital systems, depending on local scope-of-practice and supply models

Across these environments, it may be managed as hospital equipment (accessories such as spacers and adapters) and as medication stock (the canister/product itself), requiring clear ownership and governance.

Key benefits in patient care and workflow

When compared with some other inhalation delivery approaches, Metered dose inhaler MDI often offers operational advantages that matter to healthcare operations leaders:

Portability and speed: no power source required; minimal setup
Dose consistency: metering valves are designed to deliver a repeatable actuation volume under specified conditions (performance depends on correct use and maintenance)
Workflow efficiency: simpler bedside administration and fewer components than many nebulizer systems
Patient continuity: can align inpatient and outpatient regimens, supporting discharge planning and technique education
Potential infection-control advantages: as a single-patient device with a capped mouthpiece, it can reduce certain cross-contamination pathways compared with shared or improperly reprocessed equipment (actual risk depends on local practice)

A critical operational caveat: Metered dose inhaler MDI is technique-sensitive. The device may be mechanically straightforward, but effectiveness can degrade significantly with poor coordination, skipped priming, blocked nozzles, or inconsistent spacer use.

When should I use Metered dose inhaler MDI (and when should I not)?

Appropriate use cases (general)

Metered dose inhaler MDI is commonly used to deliver medications for obstructive airway conditions and related respiratory pathways, often including:

Short-acting bronchodilators and long-acting bronchodilators (product dependent)
Inhaled corticosteroids and combination products (product dependent)
Other inhaled therapies available in pressurized inhaler form (varies by manufacturer and national formulary)

From a facility standpoint, appropriate use typically means:

The right medication and strength is available in Metered dose inhaler MDI format
The patient can form an adequate seal and coordinate inhalation, or a spacer/valved holding chamber is available and indicated by local protocol
Staff can provide technique support and document administration reliably
The device is within expiry, intact, and has sufficient remaining doses

Situations where it may not be suitable

Metered dose inhaler MDI may be less suitable when any of the following are present (non-exhaustive, and decisions should follow local clinical protocols):

Inability to coordinate actuation and inhalation and no appropriate spacer/assistive device available
Severe respiratory distress where the patient cannot follow instructions or generate adequate inspiratory flow (clinical judgment required)
Reduced consciousness, agitation, or inability to maintain a mouth seal
Anatomical or procedural constraints (e.g., certain oxygen delivery interfaces) without an approved adapter pathway
Medication not available in Metered dose inhaler MDI form, or formulary restrictions apply
Device damage or contamination that cannot be resolved through approved cleaning or replacement

In mechanically ventilated patients, use is highly dependent on ventilator circuit configuration, adapters, and local respiratory care protocols. Compatibility and technique vary by manufacturer and facility.

Safety cautions and contraindications (general, non-clinical)

Because Metered dose inhaler MDI is often part of a medication regimen, many contraindications relate to the drug, not the device. From a device-management standpoint, common general cautions include:

Pressurized container precautions: do not puncture, crush, or expose to high heat; disposal requirements vary by manufacturer and local regulation
Fire and heat sources: keep away from ignition sources as a general safety measure (specific warnings vary by manufacturer)
Cross-use prevention: avoid sharing between patients unless the entire system is explicitly designed and governed for safe multi-patient use (many facilities treat inhalers as single-patient items)
Look-alike/sound-alike risk: inhalers can be visually similar; storage, labeling, and barcode workflows matter
Technique dependence: poor technique can lead to underdosing, overdosing, or medication deposition where it is not intended

This content is informational only; facilities should rely on the manufacturer’s instructions for use (IFU), local policy, and qualified clinical decision-making.

What do I need before starting?

Required setup, environment, and accessories

Before using Metered dose inhaler MDI in a clinical environment, ensure the “system” is complete—not just the canister. Typical requirements include:

Correct Metered dose inhaler MDI product (drug, strength, and formulation as ordered)
Actuator/mouthpiece housing compatible with the canister (in many products the canister and actuator are intended to be used together; mixing components may not be supported)
Spacer/valved holding chamber when indicated by protocol, patient factors, or care setting
Facemask attachment for spacer use when appropriate (commonly in pediatrics or patients unable to seal lips; device designs vary)
Personal protective equipment (PPE) per local policy
Clean, well-lit environment that supports correct identification, labeling, and documentation

In certain pathways (e.g., ventilated patients), additional accessories may be required:

In-line MDI adapter approved for the circuit type
Closed-circuit considerations to avoid circuit breaks where possible
Compatibility checks with humidification/filters (facility protocol dependent)

Training/competency expectations

Because Metered dose inhaler MDI performance is user-dependent, training is not optional. A robust competency program typically covers:

Device identification (drug class, strength, dose counter presence, expiration)
Priming rules and what events trigger re-priming (varies by manufacturer)
Correct actuation technique, timing, and use of spacers
Documentation standards (including number of actuations administered)
Cleaning and storage expectations for both inhaler and accessories
Common failure modes and escalation pathways

Many facilities include Metered dose inhaler MDI technique in nursing and respiratory therapy competency assessments and incorporate spot-check coaching at the bedside.

Pre-use checks and documentation

A practical pre-use checklist for Metered dose inhaler MDI typically includes:

Right patient / right medication / right dose verification per local medication safety policy
Confirm product name, strength, and expiry date
Inspect for damage, cracks, or missing parts (cap, actuator integrity)
Check the mouthpiece/nozzle for debris, visible residue, or blockage
Confirm dose counter status if present; if no counter, follow facility policy for tracking remaining doses (varies widely)
Confirm whether priming is required (new inhaler, long time since last use, after cleaning; rules vary by manufacturer)
Confirm patient-specific labeling requirements (common in inpatient settings)
Record administration in the medication administration record (MAR) or equivalent system, including number of actuations and any notable issues (e.g., technique limitations)

For procurement and inventory teams, documentation may also include:

Lot/batch tracking practices (varies by facility and regulation)
Recall readiness (ability to identify impacted stock quickly)
Storage condition compliance (temperature, light exposure, segregation of patient-specific items)

How do I use it correctly (basic operation)?

Basic step-by-step workflow (general)

The steps below describe common operational use of Metered dose inhaler MDI. Always follow the manufacturer IFU and facility protocol, as steps (especially priming) vary by manufacturer and formulation.

Verify and prepare – Confirm the correct Metered dose inhaler MDI product and order. – Perform hand hygiene and don PPE as required. – Ensure the mouthpiece is clean and the cap is removed.
Inspect and mix (if applicable) – Visually inspect the actuator and nozzle for debris. – Many Metered dose inhaler MDI products require shaking before actuation to mix contents; specifics vary by manufacturer.
Prime if required – Priming requirements differ by product (new device, after a defined period of non-use, or after cleaning). – Priming actuations reduce the number of deliverable doses; incorporate this into dose tracking.
Position the patient and device – Positioning is typically upright or as tolerated. – Ensure a good mouth seal around the mouthpiece, or use a spacer/valved holding chamber when indicated.
Coordinate actuation with inhalation – In many pMDIs, the user actuates at the start of a slow inhalation. – Breath-actuated variants trigger automatically on inhalation (varies by manufacturer).
Complete inhalation and pause – Follow local training for breath-hold or tidal breathing technique; the aim is typically to allow aerosol deposition. – If multiple actuations are ordered, wait an appropriate interval per protocol and IFU.
Post-dose steps – Replace the cap. – If a corticosteroid is administered, facilities often include mouth-rinsing steps in patient education materials; follow local protocol and prescriber instructions.
Document – Record number of actuations administered and any technique or device issues.

Using Metered dose inhaler MDI with a spacer/valved holding chamber

In many institutions, spacers (valved holding chambers) are used to reduce coordination demands and improve delivery consistency. General operational points include:

Insert the Metered dose inhaler MDI canister into the spacer as designed.
Ensure the spacer valve(s) move freely and the device is intact.
Actuate into the chamber and then inhale as trained (single deep breath or a series of tidal breaths depending on protocol and device design).
Clean and dry the spacer per IFU; static and residue can affect performance in some spacer designs (varies by manufacturer).

For procurement teams, spacer standardization (selecting a limited set of compatible products) can reduce training complexity and stocking errors.

Breath-actuated Metered dose inhaler MDI considerations

Breath-actuated designs aim to reduce timing errors by actuating when the patient inhales. Operational considerations include:

Confirm the device is loaded/armed per IFU.
Ensure the patient can generate sufficient inspiratory flow to trigger actuation (capability varies by patient and product).
Do not assume all “MDI” devices behave the same; breath-actuation features are product-specific.

Use in ventilated patients (high-level operational considerations)

Some facilities administer Metered dose inhaler MDI via ventilator circuits using specific adapters and protocols. Key operational themes include:

Use only adapters and placements supported by local protocol and, where available, manufacturer guidance.
Coordinate administration with ventilator phases as trained by respiratory therapy leadership.
Minimize circuit breaks when possible to reduce contamination and ventilation disruption.
Document the method (adapter used, placement) as it can affect delivery consistency.

Because ventilator circuit configurations vary widely, this is an area where facility-specific training and biomedical/respiratory governance are essential.

Typical “settings” and what they generally mean

Metered dose inhaler MDI has fewer adjustable “settings” than powered clinical equipment. Instead, dose and performance are influenced by product design and user technique:

Dose strength per actuation: fixed by the manufacturer (e.g., micrograms per puff), not adjustable by the user
Number of actuations: determined by the prescribed order and clinical protocol
Priming actuations: required under defined conditions (varies by manufacturer)
Spacer selection: chamber volume, valve design, and mask vs mouthpiece can affect ease of use and delivery (device dependent)
Temperature and storage: extreme cold/heat can affect spray characteristics; storage requirements vary by manufacturer

For operations leaders, the most meaningful “controls” are standardization, training, and reliable dose tracking rather than device knobs or calibration routines.

How do I keep the patient safe?

Safety practices and monitoring

Patient safety with Metered dose inhaler MDI starts with medication safety and extends into device handling:

Medication verification: confirm patient identity and correct medication/strength, especially where multiple inhalers are stocked
Allergy and contraindication checks: typically managed through prescribing and pharmacy workflows; staff should follow local safeguards
Technique verification: poor technique is a common cause of suboptimal effect; use teach-back methods where possible
Observe response and tolerance: follow local clinical monitoring protocols after administration, especially in acute care settings
Avoid cross-contamination: treat the inhaler and any spacer as patient-specific unless policy and device design explicitly support alternative workflows

Because Metered dose inhaler MDI is often used repeatedly over a hospital stay, safety also depends on consistent storage and labeling practices.

Alarm handling and human factors

Metered dose inhaler MDI itself typically has no audible alarms. Safety risks are therefore human-factor driven:

Dose counter misread: ensure staff are trained to interpret counters correctly and understand what “0” or “end” means for that product
“It still sprays” misconception: some inhalers may emit propellant even when medication is depleted; facilities should discourage unreliable techniques like “float tests” or guesswork, and instead use counters or defined tracking methods (varies by manufacturer)
Look-alike packaging: segregate high-risk medications and use barcode scanning if available
Actuator mix-ups: where multiple products exist, mixing canisters and actuators may affect performance and is often not intended; follow manufacturer and pharmacy guidance
Cold spray sensation: rapid aerosol expansion can cause discomfort and coughing in some users; technique coaching and spacer use may mitigate this (patient response varies)

When Metered dose inhaler MDI is used in ventilated patients, ventilator alarms (pressure/flow changes) may occur during administration depending on technique and circuit configuration. Staff should follow respiratory therapy and ICU protocols for safe coordination.

Storage, handling, and environmental safety

From a biomedical and facilities management perspective, Metered dose inhaler MDI should be treated as both medication and pressurized hospital equipment:

Store within the temperature range specified by the manufacturer.
Keep away from excessive heat and avoid storing in direct sunlight or near heaters.
Do not puncture or incinerate pressurized canisters; disposal guidance varies by local regulation and manufacturer.
Manage controlled substance considerations if applicable (product dependent and jurisdiction dependent).
Establish policies for patient-specific storage (bedside bins, medication rooms, sealed bags) to reduce mix-ups and contamination.

Emphasize following facility protocols and manufacturer guidance

The safest Metered dose inhaler MDI program is one that is standardized:

Standardize a limited set of inhaler types and compatible spacers where clinically feasible.
Use manufacturer IFU as the baseline and align training, cleaning, and documentation to that IFU.
Audit technique and documentation periodically, especially after formulary changes or staff turnover.

How do I interpret the output?

Types of outputs/readings

Metered dose inhaler MDI does not typically generate clinical “readouts” like monitors do. Its outputs are primarily status indicators:

Dose counter (if present): indicates remaining actuations or doses; designs vary (numeric, color window, staged indicator)
End-of-life cues: counter at zero, change in spray characteristics, or manufacturer-defined indications (varies by manufacturer)
Physical inspection findings: blocked nozzle, residue, damaged actuator
Smart add-ons (in some markets): electronic sensors that record actuation time, frequency, and in some designs inhalation-related parameters (availability varies by manufacturer and region)

For ventilated use, “outputs” may be indirect: changes in ventilator waveforms, pressure, or alarms during administration—these reflect the circuit interaction rather than the inhaler itself.

How clinicians typically interpret them

In clinical workflows, the most operationally important interpretations are:

Is there sufficient medication remaining to deliver the ordered doses?
Was the administration likely effective given technique and device condition?
Is this inhaler appropriate for continued inpatient use and discharge planning?

Dose counters (when present) support reliable planning: ensuring adequate supply for a shift, a ward round, or discharge. Smart tracking outputs (where used) can support adherence monitoring and pathway evaluation, but their use depends on governance, privacy rules, and local digital infrastructure.

Common pitfalls and limitations

Not all products have dose counters: dose tracking may require facility workflows (dispense date, actuation logs), which are prone to error if not standardized.
Counters may not reflect priming in the way staff expect; how priming affects remaining doses varies by manufacturer.
Visual/sound cues are unreliable: the presence of a spray does not guarantee a full medication dose.
Actuator residue can mislead: buildup may change plume shape without being obvious.
Smart sensor data is not universal: not all devices are compatible, and algorithms are not standardized across brands.

For procurement and clinical engineering leaders, these limitations highlight the value of selecting products with clear end-of-life signaling and building documentation practices that do not rely on subjective assessment.

What if something goes wrong?

A troubleshooting checklist (practical and non-brand-specific)

When Metered dose inhaler MDI does not appear to function correctly, a structured approach helps distinguish technique issues from device faults:

Stop and verify basics – Confirm correct patient and correct inhaler product. – Check expiry date and inspect for physical damage.
Check the dose counter (if present) – If the counter indicates empty/end, replace per protocol. – If the counter appears stuck or inconsistent, follow facility escalation and consider replacement.
Inspect the mouthpiece and nozzle – Look for debris, lint, or visible residue blocking the spray path. – Ensure the cap is removed and the actuator is intact.
Check assembly and seating – Ensure the canister is fully seated in the actuator. – Confirm spacer connections (if used) are secure and valves move freely.
Confirm shaking and priming steps – Many products require shaking. – Prime if required by IFU (new device, after non-use, or after cleaning); priming rules vary by manufacturer.
Assess technique – Timing errors (actuation before inhalation, too rapid inhalation, poor seal) are common. – If available, switch to a spacer/valved holding chamber to reduce coordination demands.
Environmental considerations – Extremely cold canisters may affect spray characteristics; warm-to-hand guidance may exist in IFU (varies by manufacturer). – Avoid exposure to heat or flames.
Replace if uncertain – If function remains questionable after basic checks, replacement is often safer than continued troubleshooting at the bedside, subject to local policy.

When to stop use

Stop use of Metered dose inhaler MDI and follow facility escalation pathways if:

The device is cracked, leaking, or physically compromised
There is evidence of contamination that cannot be resolved within IFU cleaning guidance
The medication identity/strength is uncertain (label damage, mix-up risk)
The patient’s condition deteriorates or expected response is not seen and urgent reassessment is required (clinical escalation)
Repeated malfunctions occur in a way that suggests a batch or design issue

When to escalate to biomedical engineering or the manufacturer

Escalation is appropriate when issues suggest a systemic problem rather than isolated user technique:

Repeated failures with the same product line, ward, or lot/batch
Dose counter defects (e.g., counter not moving despite actuations)
Adapter or spacer compatibility problems affecting ventilated pathways or standardized kits
Injury or near-miss events, including wrong-product administration linked to device similarity
Suspected product quality complaint that requires formal reporting

Biomedical engineering may support accessory standardization, storage audits, and investigation of recurring workflow failures. Manufacturer escalation is often managed through pharmacy/procurement quality channels and should align with local incident reporting and regulatory requirements.

Infection control and cleaning of Metered dose inhaler MDI

Cleaning principles (general)

Infection prevention for Metered dose inhaler MDI focuses on reducing contamination of the mouthpiece/actuator and preventing cross-patient use. Key principles:

Treat the inhaler as patient-specific unless explicitly governed otherwise.
Keep the cap on when not in use to reduce environmental contamination.
Prefer wiping and IFU-aligned cleaning rather than improvised methods that may damage plastics or valves.
Ensure hands, gloves, and storage surfaces are part of the cleaning chain; device hygiene fails if the environment is contaminated.

Because many Metered dose inhaler MDI products are supplied as medication devices rather than durable hospital equipment, reprocessing expectations differ from reusable clinical devices.

Disinfection vs. sterilization (general)

Cleaning removes visible soil and residue; it is often the first step before any higher-level process.
Disinfection reduces microbial load to a defined level; appropriate level depends on risk classification and local policy.
Sterilization eliminates all microbial life and is generally not used for Metered dose inhaler MDI actuators in routine care because materials and design may not be compatible (and because many inhalers are treated as single-patient items).

Always follow the manufacturer IFU for allowable cleaning agents and methods; compatibility with alcohols, quats, chlorine-based agents, or heat varies by manufacturer.

High-touch points to focus on

Mouthpiece opening and surrounding plastic
Cap interior and exterior
Actuator body where hands grip
Spacer mouthpiece and valve area (if used)
Facemask rim and strap points (if used)
Storage bag/label surface (often touched during administration)

Example cleaning workflow (non-brand-specific)

This example illustrates a conservative, IFU-first approach suitable for many inpatient settings. Adapt to local infection prevention policy and manufacturer guidance.

Prepare – Perform hand hygiene and don gloves. – Confirm the inhaler is patient-labeled and not shared.
Disassemble safely – Remove the metal canister from the plastic actuator if IFU permits. – Do not immerse the canister unless the IFU explicitly allows it (commonly not recommended).
Clean the actuator/mouthpiece – Rinse or wash the plastic actuator as permitted by IFU (often warm water; agent choice varies by manufacturer). – Remove visible residue and ensure the spray channel is clear.
Dry thoroughly – Air-dry completely before reassembly when required; moisture can affect spray performance and promote residue buildup. – Avoid reassembly while wet unless IFU explicitly allows.
External wipe – Wipe high-touch external surfaces with an approved disinfectant compatible with the plastics (compatibility varies by manufacturer). – Avoid pushing fibers or liquid into the nozzle.
Spacer/valved holding chamber – Clean per IFU; many require washing and air drying. – Inspect valves for sticking or damage; replace if compromised.
Reassemble and store – Reinsert canister securely into actuator. – Replace cap. – Store in a clean, designated location consistent with medication security and patient-specific labeling policy.
Document as needed – Some facilities document cleaning intervals for shared accessories (e.g., spacer stock models), while others issue single-patient spacers; policy varies.

Medical Device Companies & OEMs

Manufacturer vs. OEM (Original Equipment Manufacturer)

In the Metered dose inhaler MDI ecosystem, the “manufacturer” is typically the entity responsible for the finished, regulated product placed on the market (often a pharmaceutical company for drug–device combination products). An OEM may produce components or subassemblies—such as valves, actuators, canisters, dose counters, or packaging—under contract or supply agreements.

OEM relationships matter to hospital buyers because they can influence:

Supply continuity (single-source components can create bottlenecks)
Change control (component changes may trigger regulatory updates and can affect user experience)
Service and training materials (often delivered by the marketing authorization holder, but shaped by component design)
Complaint handling pathways (pharmacy/procurement may interact with the finished-product manufacturer even when the root cause is a component)

In practice, hospitals rarely contract directly with component OEMs for inhalers, but procurement leaders benefit from understanding the upstream ecosystem—especially during shortages or product transitions.

Demand is driven by urban population growth and chronic disease programs, with broad availability in major cities. Regional disparities exist, but the service ecosystem (pharmacies, hospitals, and clinician training) is generally more developed than in many neighboring markets.

Germany

Germany represents a mature, highly regulated market for Metered dose inhaler MDI with strong reimbursement structures and a robust pharmacy distribution network. Demand is influenced by chronic respiratory disease management and strong outpatient care pathways, with hospitals often focused on formulary alignment and discharge continuity. Procurement decisions may include device usability, dose-counter preferences, and sustainability considerations, with high overall access across urban and rural areas.

Thailand

Thailand’s Metered dose inhaler MDI demand is driven by urban air pollution, smoking-related disease burdens, and expanding chronic care programs under mixed public and private provision. Imports play a major role for many branded products, while distribution and access are typically stronger in Bangkok and major provincial centers than in remote rural areas. Hospitals often focus on balancing cost, availability, and training support to maintain correct use across diverse patient populations.

Key Takeaways and Practical Checklist for Metered dose inhaler MDI

Treat Metered dose inhaler MDI as a technique-sensitive drug-delivery medical device, not just a medication container.
Standardize inhaler types and compatible spacers where clinically feasible to reduce training burden and errors.
Verify right patient, right product, right strength, and right number of actuations every time.
Build a clear ownership model across pharmacy, nursing, respiratory therapy, and biomedical engineering.
Use barcode scanning and segregation strategies to reduce look-alike/sound-alike inhaler mix-ups.
Confirm whether the product has a dose counter and train staff to interpret it correctly.
Establish a facility-approved method for remaining-dose tracking when no counter is present.
Do not rely on subjective cues (sound, plume feel, shaking) to judge remaining medication.
Incorporate priming rules into training and documentation because priming reduces available doses.
Inspect mouthpiece and nozzle for debris or residue before administration.
Keep the cap on when not in use to reduce contamination risk.
Avoid sharing Metered dose inhaler MDI between patients unless policy and device design explicitly allow it.
Use spacers/valved holding chambers per protocol to reduce coordination errors and improve delivery consistency.
Ensure spacer valves move freely and replace damaged spacers promptly.
Align cleaning agents and methods with manufacturer IFU to avoid damaging plastics or valves.
Do not immerse or wash the pressurized canister unless the IFU explicitly permits it.
Air-dry cleaned actuators/spacers thoroughly to avoid moisture-related performance issues.
Label patient-specific inhalers clearly and store them in designated, clean locations.
Treat Metered dose inhaler MDI canisters as pressurized containers and follow heat/fire precautions.
Implement recall-ready lot/batch tracking practices appropriate to local regulation and facility risk policy.
Train staff on common failure modes: blocked nozzle, empty canister, mis-seated canister, and technique timing errors.
Use a structured troubleshooting checklist before declaring device failure.
Replace the device when function is uncertain rather than repeatedly “testing sprays” at the bedside.
Escalate repeated malfunctions through quality and incident reporting pathways.
In ventilated pathways, use only approved adapters and facility protocols to maintain circuit integrity and delivery consistency.
Document administration clearly, including number of actuations and any technique limitations observed.
Include Metered dose inhaler MDI technique checks in discharge planning workflows to support continuity of care.
Consider supply resilience (dual sourcing, safety stock policies) for high-use inhalers prone to shortages.
Review formulary changes with a training and labeling plan to prevent errors during transitions.
Coordinate procurement decisions with infection prevention to align cleaning, storage, and single-patient-use policies.
Evaluate total cost of ownership, including spacers, adapters, training time, and waste handling—not only unit price.
Ensure storage conditions match manufacturer requirements, especially in hot climates and resource-limited settings.
Monitor incident reports for trends that indicate system issues (education gaps, product confusion, storage problems).
Engage clinical champions (respiratory therapy, pharmacy) to sustain technique quality and audit compliance.
Include biomedical engineering in accessory standardization and compatibility decisions (spacers, ventilator adapters).
Plan for end-of-life disposal and environmental handling consistent with local regulation and manufacturer guidance.
Document and communicate any device-related adverse events through established regulatory reporting channels.
Maintain an updated list of approved Metered dose inhaler MDI products and accessories by unit/ward.
Use clear procurement specifications that include dose-counter preference, labeling, IFU availability, and training support.
When uncertainty exists, default to “Varies by manufacturer” and verify directly from IFU and local policy.
