Pulmonary barotrauma is a well-known but rarely seen complication of mechanical intermittent positive pressure ventilation. It is thought to be related to raised pressures within alveoli which lead to their eventual rupture and the subsequent development of respiratory embarrassment. Mishaps related to faulty one-way valves in the self-inflating, bag-ventilation devices commonly used in cardiopulmonary resuscitation (CPR) can, although rarely, lead to severe barotrauma. In this report, we describe a case of pulmonary barotrauma that appeared to be related to the "locking" of the "Ambu" bag's one-way valve in the inspiratory position during routine CPR.
肺气压伤是机械间歇性正压通气一种广为人知但却罕见的并发症。它被认为与肺泡内压力升高有关，这会导致肺泡最终破裂以及随后出现呼吸窘迫。与心肺复苏（CPR）中常用的自动充气式气囊通气设备中单向阀故障相关的意外情况，虽然很少见，但可能导致严重的气压伤。在本报告中，我们描述了一例肺气压伤病例，该病例似乎与常规心肺复苏过程中“复苏球囊”单向阀“锁定”在吸气位置有关。
