目的探讨压力调节容量控制通气在治疗小儿呼吸衰竭的应用效果。方法 34例呼吸衰竭小儿,给予压力调节容量控制通气,初调节参数:Vt。结果均上机时间38.4h,治愈24例,死亡5例,放弃5例。结论压力调节容量控制通气治疗小儿急性呼吸衰竭有较好的疗效。同步性能完好,可减少或避免应用镇静剂或肌肉松弛剂,缩短上机时间。潮气量恒定,可保障自主呼吸不稳定患儿的通气安全,避免频繁调整吸气压力。吸气流速波为减速波,可减小吸气阻力,降低吸气峰压,减少气压伤。
Objective To investigate the effect of pressure-controlled volume-controlled ventilation on pediatric respiratory failure. Methods 34 cases of respiratory failure in children, given pressure regulation volume control ventilation, initial adjustment parameters: Vt. Results were on the machine time 38.4h, 24 cases were cured, 5 died, give up 5 cases. Conclusions Pressure-controlled volume-controlled ventilation has a good effect in the treatment of pediatric acute respiratory failure. Synchronization performance intact, can reduce or avoid the application of sedatives or muscle relaxants, shorten the machine time. Tidal volume constant, can protect children with spontaneous breathing unstable ventilation safety, to avoid frequent adjustment of inspiratory pressure. Inspiratory flow wave deceleration wave, can reduce the inspiratory resistance, reduce peak inspiratory pressure, reduce pressure injury.
