干预措施:

组别:

A组(驱动压滴定PEEP+序贯肺复张)

样本量:

Group:

A group

Sample size:

干预措施:

PEEP递增法肺复张,设定PEEP5cmH2O开始,每5次呼吸增加PEEP5cmH2O,直到PEEP达到20cmH2O并维持呼吸10次,再反向操作使PEEP降到5cmH2O。 肺复张后进行PEEP 滴定,PEEP 从 20cmH2O 逐次递减到4cmH2O,每5次呼吸降低2cmH2O,与驱动压最低值相应的PEEP 值为最优PEEP值。以后每隔1小时肺复张一次方法同上。

干预措施代码:

a

Intervention:

Intervention: The PEEP incremental method for lung recruitment starts with PEEP 5 cmH2O, increasing PEEP 5 cmH2O every 5 breaths until PEEP reaches 20cmH2O and maintaining breathing 10 times. Then decrease PEEP to 5 cmH2O by the reversed operation. After lung recruitment, PEEP titration was performed. PEEP gradually decreased from 20 cmH2O to 4 cmH2O, and decreased by 2 cmH2O every 5 breaths. The PEEP value corresponding to the lowest driving pressure was the optimal PEEP value. The method of lung recruitment is the same as before every 1 hour in the future.
