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.
CONSUMABLE
SAMPLING
A sidestream gas analyzer continuously removes a gas sample flow from the respiratory
circuit, for example a nasal cannula, a respiratory mask or the Y-piece of an intubated
patient. The gas sample is fed through a sampling line to the gas analyzer. The sampled
gas is usually warm and humid, and cools down in contact with the wall of the sampling
line. Water therefore condenses in form of droplets on the inner wall of the sampling line.
These droplets could potentially occlude the sampling line and interfere with the gas
measurement.
THE NOMOLINE FAMILY
To overcome the shortfalls of current gas sampling solutions, the Nomoline Family
sampling lines have been developed for the ISA sidestream gas analyzers.
Unlike traditional solutions that remove water vapor and collect water in a container, the
Nomoline Family sampling lines incorporates a unique water separation (NO Moisture)
section, which removes condensed water. The NOMO section also has a bacteria filter
which protects the gas analyzer form water intrusion and cross contamination.
The Nomoline Family sampling lines are specially designed for 50 ml/min low sample flow
applications. The Nomoline Family sample lines have a very low dead space that results
in an ultra-fast rise time, making measurements of CO

possible even at high respiratory rates. ISA sidestream gas analyzers are therefore
suitable for adult, pediatric and infant patients.
The Nomoline Family sampling lines are available in the following versions:
(The Nomoline Family sampling lines; Nomoline with male Luer Lock connector, Nomoline
Airway Adapter Set with integrated airway adapter and the Nomoline Adapter with female
Luer Lock connector.)
