17.12 Essential Performance
Essential Performance Function
Delivery of ventilation at the patient-connection port within the alarm
limits set by the operator;
3
or
the following alarm conditions shall occur as appropriate:
• Low battery as internal electrical power source nears depletion;
• Low and High Minute Volume;
• Low and High PEEP;
• Obstruction/Occlusion;
• Low and High Air/Oxygen Inlet Pressure;
To evaluate if essential performance is maintained, the following degradations shall not be allowed in any normal
use case:
• component failures;
• changes in programmable parameters or settings;
• reset to default settings;
• change of operating mode;
• initiation of an unintended operation; and
error of Delivered Volume (V
ti
) of individual breaths greater than 35% and error of the DELIVERED VOLUME
averaged over a one minute interval greater than 25%.
