PEEP Valve
Calibration
Th e PEEP Valve callbrat/on should be performed:
• when the machine is fi陪t put into service.
• at prescribed
,
planned maintenance intervals.
• afterthe pneumatic engine has been serviced.

Callbratlon setup After completing the "Airway Sensor Span" calibration in the previous section
,
remove
the pressure sensing tee and connect the open end of the patient circuit tube directly
to the inspiratory flow patient connection.
• If you are only performing the PEEP Valve calibration
,
connect the Calibrated
Flow Orifice as detailed in the "Airway Sensor Span" setup. Then
,
connect the
open end of the patient circuit tube directly to the inspiratory flow patient
connection.
Ensure that the test tubing is leak free.
Callbratlon procedure 1. To enter the calibration menu
,
select "Next PEEP Valve Cal Menu".
2. Establish drive gas forthe ventilator.
3. Set all flow controls to minimum.
4. To start calibration , select "Start PEEP Valve Calibration".
Note: Th is calibration procedure may take up to 20 minutes.
Th e calibration status and progression bar are displayed at the bottom of the sc陀en.
Remarks Th e calibration routine opens the PEEP valve stepwise and reads the resulting airway
P陀ssure. Th e accumulated values representthe output linearity curve forthis pa削cular
PEEP valve. Th e accumulated data include:
• Lower PEEP Valve Curve
• Upper PEEP Valve Curve
• PEEPTemperature Comp
• PEEP Nominal Resistance
Theda恼 is stored in EEPROM and is used during normal operation to compensate for
伽e
individual valves output characteristics.
