微型呼吸机在院前长途转运呼吸衰竭患者中的应用
Application of micro-ventilator in patients with respiratory failure in long-distance pre-hospital transport
目的 探讨微型呼吸机机械通气转送呼吸衰竭患者的可行性及注意点,以提高转送成功率.方法 对56例呼吸衰竭患者应用大容量氧气筒并联微型呼吸机的氧源进行机械通气长途转运,观察其转运效果.结果 中枢性呼衰中pH值运送前为(6.98±0.03),运送后为(7.36±0.03),运送前后比较差异有统计学意义(t =2.57,P<0.05),转运前后其他血气分析结果明显缓解(P<0.05),PaO2正常,无明显酸碱平衡失调及高碳酸血症,转送成功率100%.结论 利用院内大容量氧气筒作用为微型呼吸机的氧源来进行机械通气转运呼吸衰竭患者可行,值得推广使用.
更多Objective To explore the feasibility and key points of micro-ventilator mechanical ventilation in patients with respiratory failure in long-distance transfer,in order to improve the success rate of transfer.Methods Large-capacity oxygen tank paralleled with micro-ventilator oxygen were used in 56 cases of respiratory failure patients in long-distance transfer,the effect of transfer was observed.Results Average pH value of central respiratory failure was (6.98 ± 0.03 ) before the transfer and (7.36 ± 0.03 ) after the transfer.The difference was statistically significant ( t =2.57,P < 0.05 ).The results of other blood-gas analysis had significant change before and after the transfer ( P < 0.05 ).PaO2 was normal.Neither acid-base balance disorder nor hypercapnia was found.Success rate of transfer was 100%.Conclusions It is feasible to use large-capacity oxygen tank as the source of oxygen for micro-ventilator mechanical ventilation in patients with respiratory failure.The method is worth extending in clinical application.
