Engaging in deep breathing exercises aids in expanding the lungs and promoting a more efficient distribution of air across all regions of the respiratory system. The patient can either sit in a chair or maintain an upright position in bed, inhaling deeply while pushing the abdomen outward to maximize the intake of air into the lungs. Subsequently, the abdomen is contracted, and the patient exhales. These deep breathing exercises are typically performed multiple times throughout the day, but for short durations.
