[Postoperative weaning from mechanical ventilation in adults]
Abstract:
Pulmonary complications remain the most frequent of postoperative complications (32-60), especially after upper abdominal surgery (14-41). Chronic respiratory insufficiency (80) also continues to be a major risk factor, in spite of the progress made in both anesthesiology and postoperative care. In the immediate postoperative period, weaning from mechanical ventilation is one of the most dangerous phases of anesthesia (84). We discuss the importance of weaning procedures, in particular, in patients with a high risk of pulmonary complications.

Tracheostomy Decannulation
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
Endotracheal Tube Extubation
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.

Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...

Ventilatory Modes
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.
Full Support Modes
Full support modes include controlled mechanical ventilation, continuous mandatory...
