monitoring
1. Select the appropriate airway adapter.
Use only accessories provided or recommended in Products and Accessories. Always
refer to the manufacturer's Directions for Use for instructions about operation,
cleaning, and replacement.
2. Connect the adapter, ventilator circuit, and CO
2
sensor according to the
manufacturer’s instructions.
3. Plug in the CO
2
sensor cable to the mainstream CO
2
connector on the Propaq left
side panel.
4. Set up the CO
2
channel and alarms. Follow the steps described on page 62.
WARNING Do not attempt to verify operation of the CO
2
sensor by blowing
through it directly. Always blow through an attached airway adapter. Otherwise, a
small amount of CO
2
from your breath may enter the CO
2
sensor housing and
cause a small shift in the measured CO
2
values. It may take 3-24 hours for the
sensor to return to proper calibration.
WARNING Do not clean and/or reuse a single-patient-use airway adapter. When
a single-patient-use airway adapter becomes occluded, replace it.
WARNING Prior to using an airway adapter, always look through the window
lumen and inspect the adapter for inadvertently lodged obstructions and for
window integrity.
WARNING If the sensor does not easily slide onto the adapter, do not attempt to
force these components together. They fit together in only one way. Take care not
to damage the glass windows.
WARNING After attaching the sensor to the adapter, check the adapter again for
proper placement of the sensor and for window integrity.
WARNING When attaching the airway adapter, position the adapter so the
sensor is on top to avoid fluid collection in the sensor airway slot. Any
concentration of fluids here can cause inaccurate CO
2
readings.
WARNING Always check to make sure there are no leaks in the breathing
circuit. Check all of the connections.
WARNING When disconnecting the CO
2
sensor from the tracheal or
endotracheal tube, check the sensor to determine how hot it is. If it is too hot for
patient comfort, do not allow it to come into contact with the patient.
