Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Perioperative airway resistance and lung function are evaluated perioperatively in patients, who undergo surgical procedures in different postures and with or without gas insufflation into the peritoneal cavity.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Lung function, upper and lower airway resistance measurements are performed in patients in prone horizontal or head tilted down (40°) position. Half of the patients with head down position will have surgery in laparoscopic technique (including gas insufflation to achieve a pneumoperitoneum). Measurements are performed on the day prior to surgery, on the morning of surgery, 30 - 45 minutes, 2 hours, and 24 hours after extubation.
