Question

What is the most common cause of post-operative hypoxemia?

1) Atelectasis
2) Pneumonia
3) Pulmonary embolism
4) Hypoventilation

Answer 1

Atelectasis is the most common cause of post-operative hypoxemia.

Step-by-step explanation:

The most common cause of post-operative hypoxemia is Atelectasis.

Atelectasis refers to the partial or complete collapse of a lung or a section (lobe) of a lung. After surgery, especially in those who have undergone abdominal or thoracic surgery, atelectasis can occur due to reduced lung volume and impaired clearance of secretions.

This can lead to a decrease in oxygen levels in the blood, resulting in hypoxemia. Atelectasis can be prevented or minimized by early mobilization, incentive spirometry, and deep breathing exercises.
