简要总结
In children under 6 years of age undergoing regular surgery during general anesthesia, the intratidal compliance profile is evaluated when different tidal volumes are applied at different positive end expiratory pressures.
Then determine the most appropriate combination of positive end-tidal pressure and tidal volume.

结局指标
主要结局
Intratidal compliance profiles in each ventilator settings
时间窗: During general anesthesia (up to about 50 min-1 hr after induction of anesthesia)
The investigators will determine Intratidal compliance profile using the changes in compliance over time --\> I, merely increasing compliance profile; IH, increasing turning into horizontal compliance profile; D, merely decreasing compliance profile; HD, horizontal turning into decreasing compliance profile; IHD, increasing turning into horizontal and further turning into decreasing compliance profile If compliance profile is I, the PEEP is low. On the other hand, compliance profile is D, PEEP level is considered to be high.
次要结局
- Driving pressure(During general anesthesia (up to about 50 min-1 hr after induction of anesthesia))
- Respiratory compliance(During general anesthesia (up to about 50 min-1 hr after induction of anesthesia))
- Blood pressure(During general anesthesia (up to about 50 min-1 hr after induction of anesthesia))
