AUTOMATIC PEEP SELECTION FOR MECHANICAL VENTILATION

The present disclosure pertains to a system (10) configured to automatically set the positive end expiratory pressure (PEEP) during mechanical ventilation (800). The system uses a measured relationship between transpulmonary pressure and lung volume (804) to set PEEP (808) such that mechanically assisted breaths are delivered more effectively to open airways (e.g., tidal breaths will be deliveredto airways that consist of alveoli that have not contracted or collapsed at the end of expiration) (810). Furthermore, the system is configured to sense (18, 804) when the lungs may be either hyperextended and/or undergoing cyclic atelectasis in order to prevent trauma or injury to the lung's fibrous tissue. The system is configured to perform recruitment and/or continuous monitoring and adjustment of the PEEP setting to maintain an open lung. 本公开涉及一种被配置为在机械通气(800)期间自动设置呼气末正压(PEEP)的系统(10)。所述系统使用测量的跨肺压(804)与肺容量(808)之间的关系来设置PEEP，以便将机械辅助呼吸更有效地递送到开放气道(例如，潮气呼吸将被递送到包括在呼气未最终没有收缩或坍缩的肺泡的气道)(810)。此外，所述系统被配置为感测(18、804)何时肺可能过度扩张和
