Abstract: Positive end-expiratory pressure (PEEP) is a common method to maintain alveolar patency in patients undergoing mechanical ventilation. However, in patients undergoing tracheotomy, alveolar collapse often occurs due to bedridden, aspiration, and other factors. There is currently no effective means to provide PEEP support for such patients. The application of a high-flow oxygen inhalation device with a PEEP valve was designed to provide patients with continuously adjustable PEEP, which helps to improve the patient's oxygenation and maintain the lung's physiological functions.
