1.3.11.5 Use of Neonatal Airway Adapter
The neonatal airway adapter should be used when monitoring patients with endotracheal
tube diameters less than or equal to 4.0 mm.
1.
Verify the windows are clean and dry. Clean or replace the adapter if necessary.
2.
Snap the airway adapter into the Capnostat® sensor. Align the line on the bottom of the
airway adapter with the line on the bottom of the Capnostat®. Press the sensor and
airway adapter together until they “click”.
3.
If necessary, perform an adapter calibration. See “Adapter Calibration” on page 44.
4.
Place the Capnostat® / airway adapter assembly between the elbow and the ventilator
circuit wye.
NOTE: Position the airway adapter with it’s windows in a vertical
and NOT a horizontal position. This helps keep patient
secretions from “pooling” on the windows.
To prevent “rain-out” and moisture from draining into the
airway adapter, DO NOT place the airway adapter in a
gravity dependent position.
FIGURE 1-21 Pediatric Airway Adapter
For routine maintenance of airway adapter, separate the system between the endotracheal
tube and the airway adapter. Lavage and suctioning of the airway can then be performed
without fluids and mucous accumulating on the neonatal airway adapter window.
5. Check that the connections have been made correctly by verifying a proper CO
2
waveform (capnogram) on the monitor display.
NOTE: The CO
2
waveform is displayed by choosing CO
2
as
Waveform 2 or 3 and the Resp Source in the Setup menu.
6. The sensor cable should face away from the patient. To secure the sensor cable safely
out of the way, attach the sensor cable holding clips to the airway tubing, then connect
the sensor cable to the clips.
