无创面罩双向气道正压机械通气(BiPAP)是一种新型无创型呼吸支持模式,患者自主呼吸不受限制不必经受气管插管,气管切开等苦痛,避免创伤大,并发症多,呼吸依赖等诸多弊端。BiPAP为双向气道正压通气,吸气相为高压,是影响潮气量大小的主要因素,呼气相为低压,即呼气终末加压(PEEP),
BiPAP is a new noninvasive respiratory support model with unrestricted spontaneous breathing in patients without the need for endotracheal intubation, tracheotomy and other pain, to avoid trauma, complications, respiratory dependence And many other drawbacks. BiPAP is bidirectional positive airway pressure, the inspiratory phase is high pressure, is the main factor affecting the tidal volume, the expiratory phase is low pressure, that is, end expiratory pressure (PEEP)
