Brief summary: This study aims to compared the effects in driving pressure of an open-lung strategy with a positive end-expiratory pressure (PEEP) titrated to best driving pressure (DP) after a RM versus the recommended protective PEEP of 5 cmH2O without a recruitment manuever in non-obese patients undergoing cardiac surgery.


Eligibility criteria: Inclusion Criteria:

* Non-obese patients scheduled for cardiac surgery (CABG and valve replacement)

Exclusion Criteria:

* i) age \<18yr or \>80yr, ii) pregnancy or breast-feeding status, and iii) patients with previous known respiratory disease, iv) Body mass index \>35 kg/m2, v) emergency surgery and vi) hemodynamic instability at entry (need of vasopressors or ionotropes at entry or a ventricular assist device.

Primary outcomes:
measure: driving pressure
timeFrame: intraoperative
Secondary outcomes:
measure: Postoperative pulmonary complications
timeFrame: 72 first postoperative hours
Other outcomes:
