Lung ventilation

Lung ventilation refers to the amount of gas in and out of the lungs per unit time. Generally refers to the dynamic capacity of the lungs, which reflects the ventilation function of the lungs. Lung ventilation can be divided into minute ventilation, maximum ventilation, ineffective cavity volume, and alveolar volume. The minute ventilation refers to the product of the tidal volume and the respiration frequency of the volume of air inhaled or exhaled by the lungs per minute. It is often seen clinically that some patients with shallow breathing will experience hypoventilation and hypoxia. When rescuing a patient whose breathing has stopped suddenly, artificial ventilation is used to expand and contract the chest of the patient to maintain lung ventilation. But pay attention not to use too much force to prevent damage to the ribs, but also pay attention to the amplitude, so that alveolar ventilation achieves sufficient results.
