Chapter 6: Service and Maintenance
Cleaning
Cleaning of the NomoLine ISA CO2 should be performed at regular intervals or in accordance
with hospital, as well as local and governmental regulations.
See Safety Information, Warnings and Cautions on page 9.
WARNING: To avoid electric shock, always physically disconnect the NomoLine ISA CO2 and
all patient connections before cleaning.
CAUTION: To avoid permanent damage to the NomoLine ISA CO2, do not use undiluted
bleach (5% - 5.25% sodium hypochlorite) or any other cleaning solution not recommended.
Note: To prevent cleaning liquids and dust from entering the NomoLine capnography gas
analyzer through its sampling gas inlet connector, keep the sampling line fitted while
cleaning NomoLine ISA CO2.
The surfaces of the NomoLine ISA CO2 may be cleaned with the following solution(s):
• 70% ethyl alcohol
• 70% isopropyl alcohol
• Glutaraldehyde Solution
• Quaternary Ammonium Chloride Wipe
• 0.5% Sodium Hypochlorite/Water Solution
• Accelerated Hydrogen Peroxide
Maintenance
Once every year it is recommended to perform maintenance on NomoLine ISA CO2. A
NomoLine ISA CO2 Maintenance Kit containing all required components and instructions to
perform maintenance procedures is available through www.masimo.com.
Operational Check
1. Connect the NomoLine ISA CO2 cable to the host device connection port.
2. Connect a NomoLine sampling line to the NomoLine ISA CO2 input connector.
3. Power up the host device.
4. Check that the LEGI indicator shows a steady green light, indicating that
NomoLine ISA CO2 is ready for use.
Note: Without a sampling line connected, the LEGI Indicator does not illuminate.
5. Breathe briefly into the sampling line and check that a valid CO
2
waveform and
values are displayed on the host device screen.
6. Occlude (obstruct) the sampling line and wait for 10 seconds.
7. Check that an occlusion alarm is displayed and that the LEGI connector shows a
flashing red light.
