Frequent coughing and deep breathing is a key strategy for preventing atelectasis after surgery. Atelectasis occurs when the alveoli in the lungs collapse, which can happen post-operatively due to factors such as shallow breathing, pain, or the effects of anesthesia. By encouraging patients to cough and take deep breaths, it helps to fully expand the lungs, clear secretions, and promote better ventilation.

Deep breathing exercises increase lung volume and help reopen collapsed areas of the lung. Coughing is important for clearing mucus that could obstruct air passages, allowing for improved airflow and gas exchange. This combination is fundamental in maintaining adequate pulmonary function and preventing complications like atelectasis, especially following surgeries that may impact respiratory function.

Other strategies, such as early mobilization and the use of incentive spirometry, can also support this approach, but the emphasis on deep breathing and coughing is particularly crucial in the immediate post-operative recovery phase.
