Diaphragm breathing and lip contraction exhalation

Diaphragm breathing refers to: when inhaling, relax the abdominal muscles, the diaphragm contracts, the position moves down, and the abdominal wall bulges; When exhaling, the abdominal muscles contract, the diaphragm relaxes, returns to its original position, and the abdomen sinks, increasing the expiratory tidal volume. When breathing, reduce the work of intercostal muscles and auxiliary breathing muscles as much as possible, and keep relaxed and rested. Increase tidal volume

Exhale with contracted lips: The patient takes a sitting position, holds his knees with both hands, and puts the tip of his tongue on the inner floor of mandibular teeth, close to the junction of hard palate and soft palate of maxilla. His tongue is slightly arched to increase the resistance of expiratory airflow, and his lips contract into a whistle. When inhaling, let the air enter through the nostrils, so that the air inhaled into the lungs can be absorbed, filtered, wetted and heated through the nasal mucosa, which can reduce the irritation to the throat and airway and prevent infection. Don't rush to exhale after each inhalation. Hold your breath for a while before exhaling. When exhaling, whistle with your lips closed, and let the gas slowly blow out the gas in your lungs through the narrowed mouth. Exhale for 4 ~ 6 seconds at a time, and then inhale gently through your nose. It is required to exhale for a long time and exhale as much gas as possible. The ratio of inspiratory time to expiratory time is 1∶2. Practice 3 ~ 4 times a day according to the above method, each time 15 ~ 30 minutes, the silent count 1 2 when inhaling, and the silent count 1 2, 3, 4 when exhaling, which can gradually prolong the expiratory time and reduce the respiratory frequency.
