目的　探讨肺结核呼吸衰竭的机械通气策略。方法　对 5 2例肺结核呼吸衰竭行肺保护性通气策略的机械通气治疗 ,观察疗效及并发症。结果　呼吸衰竭治愈 4 9例 ,死亡 3例 ,治愈率94 .2 % ,无明显并发症。结论　肺保护性机械通气对结核性呼衰治疗是安全的 ,且疗效显著 Objective To investigate the mechanical ventilation strategy of respiratory failure in pulmonary tuberculosis. Methods 52 cases of pulmonary tuberculosis respiratory failure lung protective ventilation strategy of mechanical ventilation treatment, efficacy and complications were observed. Results Respiratory failure cured 49 cases, 3 died, the cure rate was 94.2%, no obvious complications. Conclusion Lung protective mechanical ventilation is safe for treatment of tuberculosis respiratory failure, and the curative effect is remarkable
