Insufficient pressure support alarm

Is triggered if for 3 breaths in a row the maximum mask pressure achieved at inspiratory to expiratory transition is either <87.5% of the absolute mask pressure targetted at that point, or < absolute mask pressure targeted minus 1 cm H2O, whichever is the lower.

High leak alarm

Leak exceeds 30 L/min for more than 20 seconds.

Flow blocked alarm

Flow is less than 6 L/min for more than 20 seconds.

IEC 601-1 classifications

Class II, Type CF

Class II medical electrical equipment provides protection against electric shock either by double insulation or reinforced insulation and does not require a protective ground.

Inspiratory Trigger Characteristics

The inspiratory trigger occurs at a flow greater than 0 LPM when tested with EPAP=5 cm H2O, IPAP=15cm H2O, sinisoidal breath shape. The inspiratory trigger response time is <600 ms when tested with EPAP=5 cm H2O, IPAP=15 cm H2O, 0.67 L/sec inspiratory and expiratory flow rate. The time is measured from the beginning of inspiratory flow to the beginning of pressure rise to IPAP.

Note: The ASV algorithm is designed to treat a patient with essentially normal lungs. Hence, trigger response is less sensitive and pressure ramp-up is more gentle than typical non-invasive ventilators.
