The purpose of this clinical trial is to use a digital recording device integrated with an incentive spirometer to record a patient's deep breathing lung training following abdominal surgery. Through this digital recording, it will be possible to effectively assess the daily frequency, duration, depth of deep breaths, and the volume of inhalation performed by the patient during their breathing exercises. This will transform the previously difficult-to-describe deep breathing training into a digital record, allowing healthcare professionals to quickly evaluate the patient's condition. Patients can also monitor their own respiratory function changes, leading to positive health promotion benefits, accelerating their postoperative recovery, and simultaneously reducing healthcare costs and improving medical quality.
