Cardiopulmonary function is the basis of human metabolism and is an important function that is indispensable for maintaining human life. The lungs have multiple functions, such as respiratory function, endocrine function, and metabolic function. Respiratory function is to exchange gases, absorb oxygen from the external environment, and expel carbon dioxide. The pulmonary function training machine is a medical device specially designed to help patients improve and enhance lung function. This type of equipment is usually used for respiratory rehabilitation, especially for patients with respiratory diseases such as chronic obstructive pulmonary disease, asthma, pulmonary fibrosis, and postoperative recovery.
