Conditions

Patients at high risk for postoperative plumonary complications

Interventions

For patients with EIT and heterogeneous ventilation distribution (phenotype 1, phenotype 3) , PEEP setting is performed using EIT-guided ventilation distribution as an index.

Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: Patients over 18 years of age who have undergone surgical procedures Patients under ventilatory management upon return to the ICU after surgery Patients at high risk for postoperative pulmonary complications Heterogeneous ventilation distribution (phenotype 1 DFV<0.5 or phenotype 3 DFV>=0.6) within 12 hours after ICU admission

Exclusion criteria

Exclusion criteria: Patients with spinal or pelvic instability due to fractures. Patients with implantable cardioverter-defibrillators or implantable pacemakers. Patients with preoperative skin lesions, such as blisters, between the 4th and 5th ribs where the EIT belt is worn. Patients with do-not-resuscitate (DNR) orders. Patients on home ventilatory management before surgery. Patients undergoing tracheostomy. Patients with low cardiac function before surgery (left ventricular ejection fraction of 40% or less, or NYHA III or higher by echocardiography). Patients with preoperative chest CT scan or chest x-ray showing a bra or other contraindication to the recruitment maneuver. Patients with a persistent air leak from the thoracic drain or suspected intraoperative lung injury, contraindicating the recruitment maneuver. Patients with an artificial heart. Patients with extracorporeal membrane oxygenation (ECMO) support (either veno-venous (VV) or veno-arterial (VA)). Patients with a history of neuromuscular disease. Pregnant women.
