Final answer:
Pursed-lip breathing involves inhaling through the nose and exhaling through pursed lips. Deep breathing involves using the diaphragm to take deep breaths.
Step-by-step explanation:
Pursed-lip breathing and deep breathing are two techniques used to help improve breathing efficiency and manage respiratory conditions. Pursed-lip breathing involves inhaling through the nose and exhaling through pursed lips, creating a slight backpressure that helps keep the airways open and increases the time for air exchange in the lungs. This technique can be taught by instructing the patient to take a slow, deep breath in through their nose, and then exhale gently through pursed lips, as if blowing out a candle.
Deep breathing, also known as diaphragmatic breathing, involves using the diaphragm to take deep breaths, fully expanding the lungs. This technique can be taught by instructing the patient to place one hand on their abdomen and take a slow breath in, feeling their abdomen rise as they fill their lungs with air, and then exhaling slowly and fully. Both techniques can be beneficial in improving lung function, reducing shortness of breath, and promoting relaxation.
