After thoracotomy or sternotomy, lung and chest wall compliance will have a maximum decrease of what percentage after 6 days?

The significant reduction in lung and chest wall compliance following thoracotomy or sternotomy is essential for understanding the physiological implications of surgical procedures on the thoracic cavity. After a thoracotomy or sternotomy, damage to the thoracic structure, including the muscles and tissues surrounding the lungs, can cause alterations in their ability to expand and contract effectively.

Research indicates that after approximately six days following a thoracotomy or sternotomy, the maximum decrease in lung and chest wall compliance can reach around 30%. This decline is attributed to several factors, including pain, inflammation, and the accumulation of fluids in the pleural space, which can impede normal lung function and chest wall mechanics. Additionally, the surgical procedure itself may impact the integrity of the thoracic wall and the diaphragm, further contributing to reduced compliance.

Understanding this significant decrease in compliance is crucial for healthcare providers, as it emphasizes the importance of closely monitoring respiratory function and implementing appropriate interventions to enhance pulmonary rehabilitation and prevent complications associated with decreased lung function.
