Prepare to Measure AG AG and O2 Concentration Monitoring
8 - 6 046-004667-00 A7™ Operating Instructions
8.6 Prepare to Measure AG
1. Select the appropriate watertrap according to patient type and attach it to the watertrap
socket.
2. Connect one end of the gas sampling tube to the watertrap.
3. Connect the other end of the gas sampling tube to the patient via the airway adapter.
4. Connect the exhaust tube to the gas outlet on the module to scavenge the sample gas to
the waste gas disposal system.
FIGURE 8-4 Prepare to Measure AG
CAUTION:
Position the airway adapter properly so that the part connecting to the
gas sampling tube is pointing upwards. This prevents condensed water
from entering the gas sampling tube and causing an occlusion as a
result.
CAUTION: The watertrap collects water drops condensed in the sampling tube and
therefore prevents them from entering the module. If the collected
water reaches a certain amount, you should drain it to avoid airway
blockage.
CAUTION: The watertrap has a filter preventing bacterium, vapor and patient
secretions from entering the module. After long-term use, dust or other
substances may compromise the performance of the filter or even
block the airway. In this case, replace the watertrap. Replacing the
watertrap once a month is recommended.
WARNING: Do not use high volume watertraps with Infant patients. Otherwise, patient injury
could result.
WARNING: Make sure that all connections are reliable. Any leak in the system can result in
erroneous readings due to patient breathing gas mixed with ambient air.
