9.4 Essential performance
The essential performance for the ventilator system and its options are the delivery of ventilation
at the patient connection port within the alarm limits set by the user or generation of an alarm
condition.
Essential performance according to IEC 60601-1
• Oxygen level alarm conditions
• Airway pressure
• Expired volume
• Electrical supply failure
• Internal electrical power source near depletion
• Gas supply failure
• Gas temperature

9.5 Patient circuit
Patient circuit configurations
• Pediatric: 10 - 12 mm tubing, tidal volumes 20 - 100 ml
• Pediatric: 15 mm tubing, tidal volumes 20 - 350 ml
• Adult: 22 mm tubing, tidal volumes 100 - 2000 ml
Range of inspired tidal volumes
Refer to System Flow Chart, SERVO-air for information regarding patient circuit configurations
to be used with the ventilator system.
9.5.1 Patient circuit test
In the pre-use check, the patient circuit is tested to determine if it is within these recommended
ranges. If the tested parameters are within the specified ranges, the inaccuracies stated are
maintained.
