In addition, psychological factors and / or lack of relevant breathing training of patients can easily cause respiratory complications such as respiratory tract infection, atelectasis and pleural effusion in patients undergoing thoracic surgery under general anesthesia, resulting in decreased respiratory function and affecting the effect of the operation. Therefore, after undergoing cardiothoracic surgery, patients need to use respiratory exercise care devices for auxiliary training to improve the patient's recovery effect.
