Primary Outcome Measures

Name	Time	Method
The correlation between recruited volume (Vrec) and RI ratio by both single-breath method and EIT. The correlation of LUS and Vrec. After performing R/I ratio, and recruitment maneuver Perform the R/I ratio using the ventilator technique and record parameters/data from EIT. To calculate the correlation, statistically analyze the values from EIT and from the ventilator.

Secondary Outcome Measures

Name	Time	Method
Identify lung recruitability by EIT End of R/I measurement and and of RM Define the high recruiter (good response to RM) by the EIT technique and fine sensitivity, specitivity, and AUC compare to R/I ratio by single breath from ventilator
