【摘要】：目的探討機械通氣狀態(tài)下不同參數(shù)變化對腹腔壓力的影響。方法選取慢性阻塞性肺疾病(COPD)伴呼吸衰竭行機械通氣的42例患者,當患者病情穩(wěn)定后,在同步間歇指令通氣(SIMV)+壓力支持通氣(PSV)的通氣模式下,觀察吸氣平臺時間(Tplat)、吸氣時間(Ti)、呼氣末正壓(PEEP)的變化對腹腔壓力的影響。結(jié)果在SIMV+PSV通氣模式下,Tplat、Ti的變化對腹腔壓力無明顯影響(P0.05)。SIMV+PEEP0與基線值比較差異無統(tǒng)計學意義(P0.05),隨著PEEP的增加,腹腔壓力隨之升高(P0.05)。結(jié)論機械通氣狀態(tài)下,呼氣末正壓的變化將會對腹腔壓力產(chǎn)生顯著影響。選擇合理的機械通氣參數(shù)至關重要。
[Abstract]:Objective to investigate the effect of different parameters on abdominal pressure during mechanical ventilation. Methods 42 patients with chronic obstructive pulmonary disease (COPD) complicated with respiratory failure underwent mechanical ventilation. When the patients were in stable condition, the patients were ventilated under the condition of synchronous intermittent mandatory ventilation (SIMV) pressure to support the ventilation of (PSV). To observe the effect of positive end expiratory pressure (PEEP) on abdominal pressure during inspiratory plateau time (Tplat),) and inspiratory time (Ti),). Results under SIMV PSV ventilation mode, the change of Tplat,Ti had no significant effect on abdominal pressure (P0.05). SIMV PEEP0 compared with baseline value no significant difference (P0.05), with the increase of PEEP, abdominal pressure increased (P0.05). Conclusion during mechanical ventilation, the change of positive end-expiratory pressure has a significant effect on abdominal pressure. It is very important to select reasonable mechanical ventilation parameters.
