About this task

Overview

The Pneumatic Patient Alert System is a stand-alone system that allows the patient to alert the operator even when the console volume is turned down. Patient-to-Operator contact is accomplished when the patient compresses a hand-held squeeze bulb that activates an audible and visual alarm near the operator. Either a pulse or steady audible tone can be selected at the control box. The operator must reset the control box to stop the alarms. Follow the procedure below to verify proper functioning of the Pneumatic Patient Alert System.

Procedure
