A water-insensitive ventilator alarm.

Abstract:

:Most of the low-pressure ventilator alarms available have the pressure registration unit connected to the patient circuit by a narrow bore plastic tube. Condensed water in this tube will stop the correct function of the alarm in a few hours if the tube is placed after a heated humidifier. The pressure registration should be as close to the patient's tracheal tube as possible to monitor the pressure of the airway and hence a ventilator alarm with the pressure sensing unit in the patient circuit is described. The alarm has proved to be reliable, insensitive to water and very easy to adjust to maximum sensitivity.
