Performance Procedures

Testing the Monitor  

The following table lists the CO

2 

tests and summarizes how to document the test results.

Barometric Pressure Check

X1 = difference between the reference 
pressure and the measured ambient 
pressure displayed on the monitor
(-12 mmHg < X1 < +12 mmHg)

PCO

2

: P/X1/X2/X3/X4/X5/X6/X7

or

PCO

2

: F/X1/X2/X3/X4/X5/X6/X7

P = passed, F = failed

X1: xx (two digits)

X2: x.x

X3: x.x

X4: xxx

X5: x.x

X6: x.x

X7: x.x

Leakage Check parts 1 and 2

X2 = value of part 1 leakage check on 
flowmeter (X2 </= 4.0 ml/min)

X3 = value of part 2 leakage check on 
flowmeter (X3</= 4.0 ml/min)

Pump Check

X4 > 120 mmHg below the ambient 
pressure

Flow Rate Check

X5 = CO

2

 flow rate (42.5 ml/min <X5 

<65 ml/min).

CO

2

 Gas Measurement Calibration 

Check

X6 = difference between measured 
CO

2

 value and calculated value, based 

on 5% CO

2

 cal. gas (X7<2.6 mmHg, 

or 0.35 kPa)

Calibration Verification

X7 = difference between measured 
CO

2

 value and calculated value, based 

on 10% CO

2

 cal. gas.
