During intubation, exhalation is done passively as the patient breathes out through the endotracheal tube. The endotracheal tube is inserted into the patient's trachea, allowing air to flow in and out of the lungs. The exhaled air then travels up the tube and is released into the atmosphere. The process of exhalation is a natural function of the respiratory system, and the endotracheal tube simply provides a pathway for the air to exit the lungs. **

Obstructed exhalation in sleep apnea is caused by the collapse of the upper airway during sleep. This collapse can be due to a variety of factors, including excess weight or obesity, anatomical abnormalities in the airway, or relaxation of the muscles in the throat. When the airway collapses, it becomes difficult for air to flow out during exhalation, leading to obstructed breathing and disrupted sleep. This can result in symptoms such as snoring, gasping for air, and daytime fatigue. **
