This application relates to a continuous positive airway pressure (CPAP) device and a method for controlling ventilation pressure. The minimum operating pressure is determined by acquiring a preset treatment pressure and a target pressure drop. The device monitors the patient's respiratory phase transitions in real time and employs different pressure regulation strategies for the inspiratory and expiratory phases. During the inspiratory phase, the ventilation pressure is smoothly adjusted from the preset treatment pressure to the minimum operating pressure and maintained to reduce inspiratory effort. During the expiratory phase, the ventilation pressure is gradually increased from the minimum operating pressure to ensure that the ventilation pressure returns to the preset treatment pressure at the end of the expiratory phase, maintaining airway support and avoiding the risks of airway closure and central apnea. This application improves patient comfort during CPAP therapy, enhances treatment compliance, and simultaneously ensures airway support while reducing the risks of airway closure and central apnea.
