干预措施:

在所有研究测量过程中,所有患者的呼吸机设置都是标准化的,潮气量(Vt)在6-8 mL/kg的理想体重范围内,呼吸频率保持在pH 7.35至7.45之间。将Fio2设置为获得94%至98%之间的Spo2值,并在所有研究方案中保持稳定性,呼吸机模式处于压力控制模式。 PEEP的EIT滴定,1、PEEP从基线增加到21cmH2O或15cmH2O 5分钟。如果基线PEEP高于10 cmH2O,并且根据医生的评估,患者耐受增加(例如,循环受损),则PEEP增加至21 cmH2O。否则,使用15 cmH2O的PEEP。2、PEEP从21(或15)cmH2O逐步降低到0cmH2O,每2分钟以3cmH2O为步长,FiO2增加到1以维持氧合。如果在PEEP下降过程中SpO2下降到88%以下,则停止PEEP的下降。3、PEEP的最佳选择:计算了两个基于EIT的参数。根据减量PEEP试验期间计算的区域顺应性曲线的下降来估计区域塌陷和过度扩张百分比,最佳PEEP定义为累积塌陷和过度扩张百分比曲线的交点,提供塌陷和过度扩张肺之间的最佳选择。EIT滴定PEEP(Positive end expiratory pressure ,呼气末正压)

干预措施代码:

Intervention:

During all study measurements, the ventilator settings of all patients were standardized, with tidal volume (Vt) ranging from 6-8 mL/kg ideal body weight and respiratory rate maintained between pH 7.35 and 7.45. Set Fio2 to obtain Spo2 values between 94% and 98% and maintain stability throughout all study protocols, with the ventilator mode in pressure control mode. EIT titration of PEEP,PEEP was increased to 21?cmH2O or 15?cmH2O for 5?min from baseline. PEEP was increased to 21?cmH2O, if the baseline PEEP was higher than 10?cmH2O and the patient tolerated the increase, as assessed by the physician (e.g., impaired circulation). Otherwise, PEEP of 15 cmH2O was used. 3. PEEP was stepwise decreased from 21 (or 15) cmH2O to 0 cmH2O in steps of 3 cmH2O every 2?min, and FiO2 was increased to 1 to maintain oxygenation. If SpO2 fell below 88% during the PEEP decrease, the decrease of PEEP was stopped. 3. Optimal PEEP selection: Two EIT-based parameters were calculated. Regional collapse and overdistension percentages were estimated based on the decrease of regional compliance curve calculated during the decremental PEEP trial , Optimal PEEP is defined the intercept point of cumulated collapse and overdistension percentage curves, providing the best compromise between collapsed and overdistended lung.
