CARESCAPE Respiratory Modules and Airway Gas Option to patient connection
(1) E-sCO, E-sCAiO or N-CAiO module
(2) Gas sample, gas sampling line connector on the water trap
(3) Gas
sampling line
(4) Gas sampling line connector on the airway adapter; place the connector upwards
(5) Airway adapter with sampling line connector
(6) Heat and moisture exchanger with filter (HMEF) (optional)
Take the gas sample as close to the patient’s airway as possible, as shown in the illustrations,
and connect the sampling line to the patient’s airway adapter.
Position the adapter’s sampling port upwards to prevent any condensed water from entering
the sampling line.
NOTES:
•
Make sure that you are using a water trap that is compatible with the module:
− CARESCAPE respiratory modules and Airway Gas Option: D-fend Pro or D-fend Pro+
− E-miniC: Mini D-fend
•
Empty the water trap container as soon as it is half full.
•
Place the airway adapter between the HME and Y-piece.
•
Place the airway adapter with all sampling ports upwards.
•
Always check the tightness of all connections.
•
For a comprehensive list of accessories, see the "Supplies and Accessories" catalog.
•
Make sure that the gas sampling line is properly connected to the water trap and the
water trap is properly connected to the airway gas module. Gas leaks in these
connections may dilute the gas sample from the patient circuit, thus resulting in
erroneous gas readings. During normal operation, all sampled gas flows out of the
sample gas outlet. Room air is used as reference gas for the oxygen measurement and it
is mixed with the sampled gas. The sampled gas is diluted by room air so that the fraction
of room air in the exhaust gas is about 20%.
•
Calibrate the airway gas module every six months in normal use and every two months in
continuous use.
