Oxygen Module (OM) Test
This test requires that the ventilator under test have software version 11.8 or
above installed.
WARNING:
Oxygen supports combustion: Do not use oxygen while smoking or in presence
of an open flame.
WARNING:
Never use the oxygen analyzer to measure gas with a high oxygen content
after using the analyzer to measure gas with any oil vapor content. Oil vapor
contaminates tubing and can cause fire on contact with high concentrations
of oxygen.
1. Inspect the internal components of the oxygen delivery system to
verify that no damage is visible.
2. Figure 7-9 shows the test setup for the OM test.
