无创正压通气(NPPV)是指通过鼻罩、口鼻面罩或全面罩等无创性方式,将患者与呼吸机相连进行的正压辅助通气~[1]。经过三十多年的发展,NPPV在治疗阻塞性睡眠呼吸暂停综合征、心源性肺水肿和各种原因导致的急慢性呼吸衰竭中取得很大的成功,与有创正压通气(IPPV)相比,NPPV具有相关性肺炎发生率低,并可保留上呼吸道的生理性温湿化功能,维持 Noninvasive Positive Pressure Ventilation (NPPV) refers to positive pressure assisted ventilation by connecting a patient to a ventilator through a non-invasive means such as a nasal mask, oronasal mask, or full mask. After more than three decades of development, NPPV has achieved great success in the treatment of obstructive sleep apnea syndrome, cardiogenic pulmonary edema, acute and chronic respiratory failure due to various causes, and is associated with invasive positive pressure ventilation (IPPV) In contrast, NPPV was associated with a low incidence of pneumonia and retained the physiologic warm-humid function of the upper respiratory tract, maintaining
