观察了51例呼吸衰竭患者分别应BiPAP鼻罩式机械通气和经鼻气管插管机械通气的疗效,其中BiPAP组22例,经鼻气管插管组29例.两组患者治疗前血气PaO_2和PaCO_2相差不显著,提示病情程度基本相似,治疗后血气PaO_2和PaCO_2改善均十分明显,提示BiPAP除对Ⅰ型呼衰外,对Ⅱ型呼衰的治疗同样有一定疗效,特别适用于需行机械通气而又神志清醒不愿做经鼻气管插管的患者,以及经鼻气管插管行机械通气后血气仍有异常和有呼吸机依赖倾向者,但因BiPAP应用后血气改善和稳定需时相对较长,故对病情极度危重,昏迷或自主呼吸明显减弱者应用时需慎重.
Fifty-one patients with respiratory failure were treated with BiPAP nasal mechanical ventilation and mechanical ventilation through nasal endotracheal intubation, including 22 cases of BiPAP group and 29 cases of nasal endotracheal intubation group.The PaO_2 and PaCO_2 The difference was not significant, suggesting that the severity of the disease is similar to the treatment of blood PaO_2 and PaCO_2 improved significantly, suggesting that BiPAP in addition to type Ⅰ respiratory failure, the treatment of type Ⅱ respiratory failure also has some effect, especially for mechanical ventilation But consciously reluctant to do nasal endotracheal intubation patients, and nasopharyngeal intubation after mechanical ventilation is still abnormal blood gas and have a tendency to rely on ventilators, but after the application of BiPAP blood gas to improve and stabilize time-dependent Long, it is extremely critical illness, coma or spontaneous breathing significantly weaker persons need to be cautious.
