Abstract

An alarm for use with positive-pressure lung ventilators is described. The device gives audible warning if the pressure in the patient circuit fails either to exceed or to fall below 15 cmH2O within a period of 20 seconds or if the batteries are running low. No external controls are provided and the alarm is activated when a probe connected to the breathing circuit is inserted into the alarm. The probe whistles if incorrectly connected during intermittent positive pressure ventilation. Battery life in clinical practice is longer than 6 months.

摘要

本文描述了一种用于正压肺通气机的警报器。如果患者回路中的压力在20秒内未能超过或低于15 cmH₂O，或者电池电量不足，该设备会发出可听警报。该警报器没有外部控制装置，当连接到呼吸回路的探头插入警报器时，警报器即被激活。在间歇正压通气期间，如果连接不正确，探头会发出啸声。在临床实践中，电池寿命超过6个月。
