目的 探讨无创正压通气 (NIPPV)对各种呼吸功能不全的疗效。方法 采用压力支持通气 +呼气末正压 (PSV +PEEP)模式行NIPPV ,观察不同原发病病人的通气效果和通气时间。结果 NIPPV治疗的有效率达 82 9% ,心脏术后呼吸功能不全通气时间最短 ,COPD和肾移植术后肺部感染时间最长。PaO2 、SaO2 升高 ,PaCO2 、HR、R降低 (P <0 0 5)。结论 NIPPV减少了有创通气的并发症和痛苦 ,但不能完全替代有创通气。
Objective To investigate the efficacy of non-invasive positive pressure ventilation (NIPPV) on various respiratory insufficiency. Methods NIPPV was performed with pressure support ventilation + positive end expiratory pressure (PSV + PEEP) mode to observe the ventilation effect and ventilation duration of patients with different primary diseases. Results The effective rate of NIPPV therapy was 82.9%, the duration of respiratory insufficiency after cardiac surgery was the shortest, and the duration of lung infection was the longest after COPD and renal transplantation. PaO2, SaO2 increased, PaCO2, HR, R decreased (P <0 05). Conclusion NIPPV reduces invasive ventilation complications and pain, but can not completely replace invasive ventilation.
