| Device Common Name | Vented Full Face Mask |
| Classification Name | Noncontinuous Ventilator (IPPB) (21 CFR 868.5905,<br>Product Code BZD) |
| Predicate Device | AirFit F20 (K153563) |
| Device Description | The AirFit F20 is an externally placed vented mask covering the<br>mouth and the nose of the patient. It provides a seal such that<br>pressure from a positive pressure source is directed to the<br>patient's nose and/or mouth. The mask connects via a standard<br>conical connector to a conventional air delivery hose, which in turn<br>connects to the positive pressure source. The mask is held in<br>place with an adjustable headgear that straps the mask to the<br>face. |
| | The AirFit F20 mask system comprises four subassemblies:<br>cushion, frame, elbow and headgear. The elbow incorporates the<br>vent array and anti-asphyxia valve safety features. The cushion<br>and headgear are available in various sizes to fit a wide patient<br>population. |
| | AirFit F20 is a prescription device supplied non-sterile. |
| Intended Use | The AirFit F20 is a non-invasive accessory used for channeling<br>airflow (with or without supplemental oxygen) to a patient from a<br>positive airway pressure (PAP) device such as a continuous<br>positive airway pressure (CPAP) or bilevel system. |

{4}------------------------------------------------

The AirFit F20 is:

- to be used by patients weighing more than 66lb (30kg) for whom positive airway pressure therapy has been prescribed
- . intended for single-patient reuse in the home environment and multi-patient reuse in the hospital/institutional environment.

The AirFit F20 device has the following similarities to the previously cleared predicated device AirFit F20 (K153563):

- same intended use ●
- same operating principle ●
- similar design and materials which incorporates: ●
- a silicone interface providing a seal around the nose l and the mouth:
- vent holes providing continuous air leak to flush out and minimize the amount of CO2 re-breathed by the patient:
- anti-asphyxia valves (AAV) to enable the patient to breathe fresh air in the event that airflow from the flow generator is impeded;
- elbow which connects to a conventional air delivery hose via standard conical connector;
- molded plastic and silicone components and fabric/foam headgear - all deemed biologically safe (ref: ISO 10993-1);
- Both masks are offered in various sizes to ensure adequate fit over the extended patient population.
- . similar performance i.e both masks operate on the same flow generator settings and have similar pressure-flow characteristics and flow impedance.
- . same operating environments i.e reuse in the home and hospital / institution environments
- . similar manufacturing processes

The following are the main differences between the subject AirFit F20 and the previously cleared predicated device (AirFit 20 (K153563)):

- . all components of the mask system can be reprocessed:
- -In the predicate device. the cushion can be reprocessed via high level thermal disinfection, high level chemical disinfection, and STERRAD sterilization, while the elbow can be reprocessed via STERRAD sterilization.
- In the subject device, the elbow, frame and headgear can all be processed via high-level thermal disinfection. The cushion maintains the same reprocessing methods as the predicate device.
- Material changes to the elbow, frame, and headgear ● assemblies

Non-Clinical Data Validation testing has demonstrated that the material changes and expansion of the multi-patient reuse reprocessing claims does not raise new questions of safety or effectiveness.

# Similarities and Differences with the Predicate Device

{5}------------------------------------------------

Non clinical testing included:

- Bioburden efficacy tests which demonstrated that the ● modified device meets the same cleaning and microbicidal bioburden efficacy performance as the predicate device.
- . Performance tests before and after the additional reprocessing claims to demonstrate that the modified device continues to meet the same performance specifications as the predicate device, including:
- -Visual inspection
- -Total mask flow
- AAV activation / deactivation -
- Assembly integrity "
- -Mask to headgear connections
- Residual toxicity tests, including cytotoxicity testing per ● ISO 10993-5, which demonstrated that the modified device remains as safe as the predicate device if the reprocessing steps provided in the labelling are followed
- . For the material changes requiring additional testing, the following biocompatibility tests were conducted:
- Cytotoxicity testing per ISO 10993-5 "
- Sensitization testing per ISO 10993-10 -
- Irritation testing per ISO 10993-10 -
- Genotoxicity per ISO 10993-3 -
- -Acute systemic toxicity per ISO 10993-11
- Material-mediated Pyrogenicity per ISO 10993-11 -
- Implantation per ISO 10993-6 -
- Leachables testing per ISO 10993-17 -

### Substantial Equivalence Conclusion

The new AirFit F20 is substantially equivalent to the predicate device:

- it has the same intended use -
- it has similar technological characteristics -
- it has similar performance characteristics -
- the difference do not raise any new questions of safety or effectiveness
- it is at least as safe and as effective as the predicate device.
