Monitoring
1. Select the appropriate airway adapter.
Use only accessories provided or recommended in the Welch Allyn Products and
Accessories booklet. 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.
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.
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.
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.
After attaching the sensor to the adapter, check the adapter again for proper
placement of the sensor and for window integrity.
