颈髓损伤后呼吸衰竭机械辅助呼吸模式比较

目的比较颈髓损伤后呼吸衰竭患者使用压力支持通气模式（PSV）与同步间歇指令通气模式（SIMV）的差异。方法观察34例患者在PsV与SIMV时血气分析、呼吸频率、心率、血压、患者主观舒适度的变化。结果在两种通气模式下，患者血压的变化无显著性差异（P〉0．05），血气pH值、PaO2、呼吸频率、心率、主观舒适度有非常显著性差异（P〈0．01），PaCO2有显著性差异（P〈0．05）。PSV模式优于SIMV模式。结论PSV模式较SIMV模式更适合颈髓损伤后呼吸功能不全时的治疗。

Comparison of pressure support ventilation or synchronized intermittent mandatory ventilation for respiratory failure after cervical spinal cord injured

ObjectiveTo observe the difference between pressure support ventilation(PSV) and synchronized intermittent mandatory ventilation(SIMV) in cervical spinal cord injury patients with respiratory failure.MethodsThe blood gas analysis,respiratory rate,heart rate,blood pressure and subjective feelings were observed in the same patient under different ventilation(PSV or SIMV).ResultsThere was no significant difference in blood pressure when patients underwent PSV and SIMV.Otherwise,There was significant difference in respiratory rate,heart rate,pH,PaO_2,PaCO_2 and subjective feelings when patients underwent PSV and SIMV,which showed that of PSV were better.ConclusionThe effect of PSV was better than that of SIMV on respiratory failure after cervical spinal cord injury.
