Performance Procedures

Testing the Monitor  

Check the barometric pressure value in the CO

2

 module as follows:

1

Enter  the  Power-Up Defaults Menu (see ““Power-Up Defaults Menu” on 
page 5-3“for instructions on accessing this menu).

2

Select the Enter Diagnostic Mode? option.

3

From the popup menu, select Yes. The Diagnostic Menu displays.

4

Select the CO

 Test option.

5

Connect a FilterLine to the CO

2

 patient monitoring input connector. This 

activates the pump in the CO

2 

module.

6

Check the status line at the top of the screen. It will display "CO

2

 pressure in 

mmHg (ambient/cell) xxx/yyy" where xxx is the ambient pressure and yyy is the 
measured cell pressure. The values are displayed with a resolution of 2 mmHg 
(0.3 kPa) up to 475 mmHg (63.2 kPa) and a resolution of 1 mmHg (0.1 kPa) 
from 475 mmHg (63.2 kPa) to 825 mmHg (109.7 kPa). Check whether the 
ambient pressure (X1) matches (within the acceptable tolerance of ±12 mmHg) 
the reference value you have received. If so, proceed to the “Leakage Check”. If 
the value is not correct, calibrate as follows.

7

Select Set Barometric Pressure (mmHg). An adjustable value in mmHg is 
activated.

8

Select the value that matches the reference value received from a reliable local 
source, such as an airport, regional weather station or hospital weather station.

9

If the selected value is not with ±12mmHg (1.6 kPa) of the current measured 
ambient pressure, verify the reference value by getting another reading from a 
different source. If the ambient pressure displayed also differs from the new 
reference by more than ±12mmHg (1.6 kPa), the CO

2 

module should be 

replaced.

10

Confirm the barometric pressure setting by clicking on the adjusted value so that 
it is no longer highlighted.

11

Check that the ambient pressure displayed in the CO

2 

Pressure line at the top of 

the screen is the same as the value that you selected from the list in Step 8.
