NOTE:
1 Replace the airway adapter, if excessive moisture or secretions are observed in the
tubing or if the CO

waveform changes unexpectedly without a change in patient
status.
2 To avoid infection, use only sterilized, disinfected or disposable airway adapters.
3 Inspect the airway adapters prior to use. Do not use it if airway adapter appears
damaged or broken. Observe airway adapter color coding for patient population.
4 Periodically check the flow sensor and tubing for excessive moisture or secretion
