Using the RespSense II Monitor
c. Release gas for 1 – 3 seconds (until the ball rises to the top of the column) and then
turn off the gas valve. This equals one exhale. The ball should return to the bottom of
the column when the gas valve is turned off. Repeat 2 – 3 times.
d. Verify the EtCO
2
reading on the display. A reading of 33 – 43 mmHg (4.4 – 5.7 kPa) is
considered normal. This should agree with the device accuracy claims found in the
section.
CAUTION:
If the EtCO
2
value is out of normal range (4.4 – 5.7 Vol%/kPa or 33 –
43 mmHg) an internal air leak is possible. Replace the single-use, disposable
moisture trap and perform the calibration procedure. If the problem persists, contact
Nonin Technical Service.
