目的观察呼吸机无创通气治疗矽肺合并Ⅱ型呼吸衰竭患者pH值、PaO2、PaCO2、SaO2的变化,以评价该治疗方法的效果。方法选择两年来进行面罩无创双水平气道正压机械通气辅助治疗的11例矽肺合并Ⅱ型呼吸衰竭患者,应用美国Espironis(伟康)公司生产的S/T型双水平气道正压(BiPAP)呼吸机,每日上机一二次,每日6h或以上,5d为1个疗程。5d天后复查动脉血气情况。结果11例患者在无创通气后各项指标均有明显变化。结论呼吸机无创通气治疗矽肺合并Ⅱ型呼吸衰竭效果确切。
Objective To observe the changes of pH, PaO2, PaCO2 and SaO2 in patients with silicosis and type Ⅱ respiratory failure treated by ventilator non-invasive ventilation to evaluate the effect of this treatment. Methods Eleven patients with silicosis and type Ⅱ respiratory failure who underwent noninvasive and bi-level positive airway pressure mechanical ventilation for two years were enrolled in this study. The patients were treated with bi-level positive airway pressure (BiPAP) by American Espironis Company Ventilator, on the machine one or two times a day, daily 6h or more, 5d for a course of treatment. 5d days after the review of arterial blood gas situation. Results All the 11 patients showed significant changes after noninvasive ventilation. Conclusion Ventilator noninvasive ventilation is effective in treating silicosis with type Ⅱ respiratory failure.
