K. Oxygen Module Operation
Note: To perform this test it is necessary that the Vision unit being tested have at least 11.8 / 12.4 / 13.4 software. If
your Vision unit has earlier software, it is mandatory that it be upgraded before performing this test.
Note: See Figure 8-8 for assistance in connecting oxygen analyzer.
WARNING: Oxygen supports combustion. Do not use oxygen while smoking or in the presence of an open
flame.
WARNING: Never use the analyzer to measure gas with a high oxygen content following use on air with an oil
vapor content. The oil vapor will contaminate the tubing and may result in a fire on contact with
high oxygen levels.
Oxygen Module Test Procedure
Step 1
Prior to performing this test, a visual inspection should be made of the internal components
of the oxygen delivery system including tubing, to ensure that there are no faulty items.
Step 1A Connect the 6 foot smooth inner lumen tubing from the outlet of the Vision, to the Whisper Swivel,
then to a pressure pick-off port (O
tubing (approximately 6 inches) may be needed between the pressure pick-off port and the test lung.
Connect the oxygen analyzer cell in the patient circuit.
Put the pressure tubing from the pick-off port to the unit's patient pressure connection.
Or, Using a "T" connector, connect the pressure pick-off port, the unit's patient pressure connection
and the oxygen analyzer inlet together, whichever applies.
Set the test lung to have a compliance of 0.04 and a parabolic resistance of 20.
Step 2 Turn on the Vision unit.
Step 3 On the unit, press Parameters and set the following unit parameters.
IPAP = 20 cm H
EPAP = 4 cm H
RATE = 15 BPM
Timed Insp. = 1.0 sec
IPAP Risetime = .05 sec
O % = 21%
