7. If applicable: Perform a tightness check of the patient circuit with the sampling line attached.
18.3.1.2 System Setup for Analyzer
If your system is using the plug-in and measure ISA analyzer, please follow the setup instructions
below:
1. Connect the ISA analyzer interface cable to the monitor.
2. Connect a Nomoline sampling line to the ISA analyzer input connector.
3. Connect the gas sample exhaust port to a scavenging system or return the gas to the patient
circuit.
4. Power up the monitor.
5. A green LED indicates that the ISA analyzer is ready for use.
6. Perform a pre-use check as described in section Perform a pre-use Check.
18.3.1.3 Zeroing
The infrared module needs to establish a zero reference level for the CO
agent gas measurement. This zero calibration is here referred to as "zeroing".
ISA analyzer performs zeroing automatically by switching the gas sampling from the respiratory
circuit to ambient air. The automatic zeroing is performed every 24 hours, and takes less than 3
seconds for ISA CO
2
If the ISA analyzer is fitted with an oxygen sensor, the automatic zeroing will also include room
air calibration of the oxygen sensor.
1 Since a successful zeroing requires the presence of ambient air (21% O
in the ISA analyzer, ensure that the ISA analyzer is placed in a well ventilated place.
Avoid breathing near the ISA analyzer before or during the zeroing procedure.
2 The sampling line should be replaced every two weeks, otherwise it is clogged.
18.3.1.4 Maintenance
GAS readings should be verified by conducting the recommended maintenance checks. For
details, please refer to Chapter Maintenance.
1. The Nomoline sampling lines are non-sterile devices. To avoid damage, do not
autoclave any parts of the sampling line.
2. Never sterilize or immerse the ISA analyzer in liquid.
