Abstract

The invention discloses an alveolar ventilation monitoring system based on a non-invasive ventilator and a control method. The system comprises a breathing machine body, a user breathing end, an MCU and a display screen, wherein an air pressure electric adjusting module is arranged in the breathing machine body, and a differential pressure type flow sensor and a first pressure sensor are arrangedat the output end of the air pressure electric adjusting module; the air pressure electric adjusting module, the differential pressure type flow sensor and the first pressure sensor are all electrically connected with the MCU; and the differential pressure type flow sensor and the first pressure sensor acquire the gas flow and pressure output by the air pressure electric adjusting module respectively, and the MCU acquires detection data of the differential pressure type flow sensor and the first pressure sensor and displays the detection data through the display screen. The breathing state ofa patient can be monitored, the airflow pressure is intelligently compensated and adjusted according to the breathing state of the patient, the patient is helped to keep the optimal breathing state, and a powerful guarantee is provided for lung treatment of the patient.

Description

technical field [0001] The invention belongs to the technical field of medical ventilator systems, in particular to an alveolar ventilation monitoring system and control method based on a noninvasive ventilator. Background technique [0002] In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. Ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. [0003] Common signs of coronavirus include respiratory symptoms, fever, cough, shortness of breath and difficulty breathing. In more severe cases, infection can lead to pneumonia, severe acute respiratory s...
