What is the primary expected outcome of deep-breathing exercises following a thoracotomy?

The primary expected outcome of deep-breathing exercises following a thoracotomy is the expansion of the alveoli. After this type of surgery, patients can experience reduced lung volumes and atelectasis (collapse of lung tissue) due to pain, restricted movement, or shallow breathing patterns. Deep-breathing exercises help to promote ventilation, allowing air to reach the alveoli more effectively. This is crucial for improving gas exchange and preventing complications such as pneumonia or further lung collapse.

Through these exercises, the patient's thoracic cavity can expand more fully, leading to increased air entry and the re-inflation of collapsed alveoli. Encouraging this expansion not only enhances oxygenation but also aids in the clearing of secretions, further supporting recovery after surgery. Thus, helping the alveoli to open up is fundamental in optimizing pulmonary function following a thoracotomy.
