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.

The application discloses a ventilation mode control method and a breathing machine in the technical field of respiratory medical equipment, reconstructs pressure distribution in a breathing cycle, adopts a control strategy that inspiratory airway positive pressure is lower than expiratory airway positive pressure, actively reduces pressure to a lower release level to reduce inspiratory load when detecting patient inspiration, and smoothly restores pressure to a higher treatment pressure at the end of expiration to establish support for the next inspiration cycle. The method is realized in the breathing machine through cooperative control of a sensing unit, a processing unit and a pressure generating unit, solves the technical problem that the existing continuous positive airway pressure mode maintains constant high pressure in the whole breathing cycle, causes heavy load and poor comfort during patient inspiration and most of the expiration stage, and improves the overall comfort and long-term use compliance of treatment while ensuring equivalent airway support and treatment effect of the traditional mode.

A respiration device is for positive pressure ventilation and continuous positive airway pressure treatment for neonatal resuscitation. The respiration device includes a body part with a) a breathing gas inlet fluidly couplable to a breathing gas supply, b) a breathing gas outlet in fluid communication with the breathing gas inlet and fluidly couplable to a patient interface, c) a first outflow port, and d) a second outflow port for releasing breathing gas from the body part, the second outflow port being fluidly couplable to one or both an expiration valve and an expiratory branch of a ventilation machine; and a continuous positive airway pressure, CPAP, generator fluidly coupled between the breathing gas inlet and the breathing gas outlet to generate a positive end-expiratory pressure for CPAP treatment. The respiration device is operable in a CPAP mode for CPAP treatment and a positive pressure ventilation, PPV, mode for PPV treatment.

The present subject matter relates to a method of diagnosing and treating sleep apnea (SA) in a patient. The method may include determining whether the patient needs a polysomnography (PSG) by obtaining a biological sample from the patient to determine if the subject has a protein selected from the group consisting of B3GNT2, LDHA, and H6PD / G6PE. The expression of one of the proteins may be associated with the presence of SA in a patient. If the patient has a protein associated with the presence of SA, then the method includes conducting a Polysomnography (PSG) on the patient to further determine if the patient has SA. If the patient is further determined to have SA, the method may then include treating the patient with a treatment of SA selected from the group consisting of ENT multilevel surgery, continuous positive airway pressure (CPAP) therapy, and bariatric surgery.

The system further optimizes patient care through improved mask seal integrity, easier provider training, and cost savings for healthcare providers.

A continuous positive airway pressure device has a shell, a diversion sound-absorbing foam pad, a blower, and a partition. The shell has an inlet and an outlet. The diversion sound-absorbing foam pad is disposed inside the shell and forms an airflow passage extending tortuously inside the shell. The blower is disposed on the diversion sound-absorbing foam pad and fluidly communicates with the airflow passage and the outlet of the shell. The partition covers the blower and the diversion sound-absorbing foam pad and has a leading hole fluidly communicating with the airflow passage and the inlet of the shell. After air flows into an interior space of the shell, the air flows through the airflow passage being tortuous and then flows out from the shell, which lengthens flow path of the air, reduces noises generated during the air flowing, and helps the air to flow more fluently.
