7.1.7 Measure breathing
circuit resistance
The breathing circuit resistance is calculated from the amount of resistance
created when 60 l/min is flowing through the circuit. It is calculated and
displayed on the bottom of the screen. It represents the resistance of 1/2 of
the breathing circuit.
7.1.8 Air inspiratory
flow sensor
calibration check
This check verifies that the Air Flow Sensor is functioning and compares the
flow and temperature measurements with the total flow sensor at 30 l/min.
Total flow and Air flow must be within 15% and temperature must be within
9° C.
Failure can be due to lack of flow as well as flow or temperature differences.
Use the EC Service Application (Section 8.5) to simulate the test and isolate
the problem.
If this check fails, all ventilator functions will still be available. The message
FlAir Control Error
will be displayed.
7.1.9 O
2
inspiratory
flow sensor
calibration check
This check verifies that the O
2
Flow Sensor is functioning and compares the
flow and temperature measurements with the total flow sensor at 30 l/min.
Total flow and O2 flow must be within 15% and temperature must be within
9°C.
Failure can be due to lack of flow as well as flow or temperature differences.
Use the EC Service Application (Section 8.5) to simulate the test and isolate
the problem.
If this check fails, all ventilator functions will still be available. The message
FlO2 Control Error
will be displayed.
7.1.10 O
2
sensor test
and calibration
This test/calibration will only be performed if both Air and O
2
are connected.
The O
2
offset is calibrated while flowing 30 l/min of Air, and the O
2
gain is
calibrated with 30 l/min of O
2
. The test will FFFFaa
a
aiiiillll if either Air or O2 fail to
achieve 30 l/min flow.
Calibration is verified by flowing 15 l/min Air and 15 l/min O
2
and comparing
the sensor output to the calculated valve (approximately 60.5%). The test will
FFFFaa
a
aiiiillll if O2 sensor is not within 5% of the calculated value.
If this check fails, all ventilator functions will still be available.
Note: This test is performed before the O
2
inspiratory flow sensor calibration
check.
