Patient hazard - disregarding alarm signals
Alarms ignored by the operator can cause serious injury to the patient.
▪
Ensure that the volume of the alarms is high enough to be heard.
▪
If the audible signal of the alarms is interrupted, the patient must be
monitored continuously.
▪
The air flow to the water chamber must not be interrupted. An
interruption can prevent alarm signals from being triggered.
