Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The main questions it aims to answer are:
* The increase in atelectasis after induction of general anesthesia in supine and Trendelenburg position compared with baseline (spontaneous breathing)
* The eventual possibility of reversal of atelectasis caused by general anesthesia and Trendelenburg position by reverse Trendelenburg position and recruitment manœuvre.
Participants will be adult, autonomous and able to express their will, undergoing elective gynecological or urological surgery in the extended Trendelenburg position.

RANDOMIZED
PARALLEL
2. Induction, intubation and mechanical ventilation for 5 minutes.
3. 2nd measurement (T1-LYING): after induction.
4. Trendelenburg 30° and ventilatory constant parameters.
5. 3rd measurement (T2-TREND): after 5 minutes of Trendelenburg.
6. Division into 2 groups according to randomization:
I. Supine position and recruitment manoeuvre. 4th measurement after 5 minutes. (T3-RM) II. Either put in the Anti Trendelenburg position. 4th measurement after 5 minutes. (TREND Q3- REV)
7. Horizontal supine position and surgical incision.
