Pressure control method for a ventilator, ventilator and storage medium
By dynamically identifying the inspiratory, expiratory, and transitional phases of the ventilator, and combining explicit physiological and implicit learning characteristics, the treatment pressure is adjusted in real time, solving the problem that traditional ventilators cannot respond to changes in the patient's respiratory status, thus improving patient comfort and treatment compliance.

AI Technical Summary
Traditional ventilators use a fixed pressure value throughout the sleep cycle, which cannot respond to changes in the patient's breathing status in real time. This causes patients to feel uncomfortable during the inhalation or exhalation phases and lacks precise feedback on fine-grained division of the breathing process and abnormal breathing events.
By acquiring respiratory airflow signals, the system dynamically identifies the inhalation, exhalation, and transition phases. Combining explicit physiological characteristics and implicit learning characteristics, the system adjusts the treatment pressure in real time, including pressure regulation during the transition phase, and monitors abnormal respiratory events in real time.
It improved the matching degree between ventilator treatment pressure and patient's respiratory status, enhanced patient ventilation comfort and treatment compliance, and strengthened the ability to respond to abnormal respiratory events.
