无自主呼吸

为避免缺氧，对于有自主呼吸的患者，吸引时间不宜超过30s，无自主呼吸的患者，不宜超过20s。

The paper suggested that the suction time should be less than 30 seconds for patients with autonomous respiration and it should be less than 20 seconds for patients with apnea .

方法：对意识不清、呼吸微弱且不规则或深昏迷、无自主呼吸者立即行MV，根据血气分析结果调整呼吸机参数。

Methods : MV was promptly applied to the patients with symptoms of unconsciousness , deep coma , irregular breath and no autonomous respiration , and adjustment of MV parameter was made based on the blood gas analysis .

方法：31例无自主呼吸的患者，用高频喷射呼吸机持续、常频、控制呼吸，通气频率16～20次／min，持续通气时间12～72h。

Methods : Normal frequency ventilation of high frequency jet respirometer was used to control breath continuously for 31 cases without autonomous breath , the ventilation frequency : 16 ~ 20 times / min with continuous ventilation time 12 ~ 72 hours .

术后7例患者均带气管插管回病房，其中6例呼吸循环稳定，1例无自主呼吸需机械控制呼吸，血压不稳定需多巴胺持续泵注维持血压。

All of the seven cases were back to the ward with endotracheal intubation , six cases of seven were stability with respiratory and circulatory , but one case have no spontaneous breath and controled breath with ventilator , and maintained blood pressure with dopamine .
