What is a common indication for the use of deep breathing exercises?

Deep breathing exercises are commonly employed to prevent atelectasis, which is the collapse of part or all of a lung. When patients are unable to take deep breaths—often due to factors like pain, intubation, or post-operative conditions—they may not fully expand their alveoli. This can lead to the accumulation of secretions and a higher risk of infection, as well as impede gas exchange in the lungs.

By encouraging deep breathing, patients can effectively expand their lung capacity, mobilize secretions, and maintain optimal respiratory function. This is particularly important after surgeries or in individuals with conditions that limit normal breathing patterns. Enhanced lung expansion through these exercises reduces the likelihood of atelectasis developing, promoting better overall lung health and recovery.

Other options, while related to general health, do not directly connect to the primary purpose of deep breathing exercises in a medical context. For instance, promoting relaxation is a beneficial effect but not the primary clinical focus. Increasing blood pressure contradicts the usual calming and stabilizing effects of deep breathing. Enhancing digestion is relevant in a broader wellness sense, but it is not the main intent of deep breathing practices, especially in a clinical or therapeutic setting.
