6 Ways We Prove Your Device Delivers Every Breath Right

A nebulizer or ventilator circuit that looks fine on the shelf can still starve a patient of medication, leak breathable pressure into the room, or deliver aerosol particles too large to ever reach the lower airway.

Respiratory and Aerosol Device Testing answers the question a visual inspection never can: does the device move air with the resistance it claims, does it hold pressure without leaking, and does the medication it aerosolizes actually reach the part of the lung it’s meant to treat. Our Respiratory and Aerosol Device Testing programme at the Oragadam laboratory covers six checkpoints across connector integrity, airflow, pressure, and aerosol performance, referenced to EN 13544-1 for nebulizing systems, ISO 23328-1 for breathing system filters, ISO 80601-2-12 for ventilators, and USP <601> for aerosol particle size.

Connector integrity testing confirms every fitting in the breathing circuit seals correctly and resists dye penetration under pressure, because a single loose connection anywhere along the circuit undermines every downstream measurement of flow and pressure. Airflow resistance testing for medical device breathing circuits measures how much resistance a patient encounters when inhaling and exhaling through the device on a calibrated breathing simulator head, confirming the resistance stays within the range a compromised patient can actually tolerate. Leakage testing pressurizes the assembled circuit to confirm no breathable gas escapes anywhere along its length, since a leak in a ventilator circuit means the delivered volume never matches the volume the machine reports.

Pressure drop testing quantifies the pressure lost across filters, valves, and tubing under simulated breathing flow, because excessive pressure drop forces a patient to work harder for every breath even when the device otherwise passes every other check. Nebulizer output testing for medical device inhalation systems measures how much medication actually leaves the device per minute, confirming the dose a clinician calculates on paper is the dose a patient actually receives, and aerosol particle size distribution testing for medical device nebulizers characterizes the droplet size spread produced, since particles outside the respirable range simply deposit in the mouth and throat instead of reaching the lungs. Manufacturers bring their programmes to Kiyo R&D Lab because a single missed checkpoint in Medical Device Testing doesn’t surface as a bench-test footnote — it surfaces as an under-dosed patient, a leaking ventilator circuit, or medication that never reaches the airway it was meant to treat. Running all six checkpoints under one accredited scope at Oragadam, with reports formatted for direct regulatory submission, is what turns respiratory device testing into evidence your quality team can actually stand behind.
