Indication Status
Steady blue light Anesthetic agent present
Steady red light Sensor error
Blinking red light Check sampling line
Remark: the blue light is applicable to ISA AX+ and ISA OR+.
19.3.2.1 Performing a Pre-use Check
Before connecting the Nomoline sampling line to the breathing circuit, do the following:
1.
Connect the sampling line to the ISA gas inlet connector (LEGI).
2.
Check that the LEGI shows a steady green light (indicating that the system is OK).
3.
For ISA OR+ and ISA AX+ module with O
2
option fitted: Check that the O
2
reading on the
monitor is correct (21%).
4.
Breathe into the sampling line and check that valid CO
2
waveforms and values are displayed
on the monitor.
5.
Occlude the sampling line with a fingertip and wait for 10 seconds.
6.
Check that an occlusion alarm is displayed and that the LEGI shows a flashing red light.
7.
If applicable: Perform a tightness check of the patient circuit with the sampling line attached.
19.3.2.2 Leakage Check
1. Connect a new Nomoline sampling line with male luer lock to the ISA LEGI and check that
the LEGI shows a steady green light.
2.
Connect a short silicon tubing with an inner diameter of 3/32” (2.4 mm) to the Nomoline
male luer.
3.
Exhale a long breath into the silicon tubing until the CO
2
concentration is greater than 4.5
vol% or 34 mmHg.
4.
Quickly connect the silicon tubing tightly to the exhaust port.
5.
Wait 1 minute until the CO
2
concentration has stabilized. Note the value.
6.
Wait 1 minute and check that the CO
2
concentration has not decreased more than 0.4 vol% or
3 mmHg. If it has decreased more there is a major leakage in the ISA unit or in the Nomoline.
Do not operate the ISA if there is a major leakage in the unit.
19.3.2.3 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
