Lung Collapse
Conditions
Brief summary
The aim of this study was to compare the effects of adding a recruitment maneuver (RM) to low tidal volume (VT) ventilation, with or without an individualized post-RM positive end-expiratory pressure (PEEP) setting in lung-healthy patients during anesthesia.
Interventions
PEEP titration trial for best Cdyn after the alveolar recruitment maneuver
Fixed standard PEEP after the alveolar recruitment maneuver

Eligibility
Inclusion criteria
* ASA physical status I-III undergoing elective major abdominal surgery including pancreatic-duodenectomy, gastrectomy and liver resection
Exclusion criteria
* i) laparoscopic surgery, ii) patients with previous respiratory disease.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| driving pressure | intraoperative | The driving pressure is a physiological ventilatory parameter measured as platteau pressure minus PEEP. This parameter may be associated with postoperative pulmonary complications |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| ventilatory efficiency | intraoperative | Ventilatory efficiency measured with volumetric capnography which includes dead space and tidal elimination of carbon dioxide. |
