Automatic Oxygen Administration After Major Abdominal and Thoracic Surgery (FreeO2PostOp)
Automatic Oxygen Administration in Early and Late Postoperative Hypoxaemia Prevention After Major Abdominal and Thoracic Surgery
The aim of the study is to assess the use feasibility of the FreeO2 system so as to deliver automatically oxygen in the post anesthesia care unit in a patient population admitted for major abdominal and thoracic surgery.
The investigators' hypothesis is that FreeO2 system will provide a better control of the oxygen saturation and reduce postoperative hypoxaemia.
