Neocoronal pneumonia, as the name implies, is the main part of the neocoronavirus attack, which can lead to pulmonary fibrosis.
The main function of the lungs is to ventilate. We breathe and exchange the oxygen in the air through the lungs into the blood and expel the carbon dioxide from the body. Once fibrosis occurs in the lungs, the entire lung becomes inelastic like wood, and the respiratory function is significantly weakened. In severe cases, various lung tissues are almost necrotic and eventually cannot breathe spontaneously and die. The ventilator is an effective method that can artificially replace the autonomous ventilation function. By delivering oxygen in vitro, the oxygen content in the blood is sufficient to maintain the vital activity needs of critical patients and to gain time for more clinical treatment methods.
The GFS131 flow sensor is an important component in the ventilator's air circuit system. It is responsible for converting the inhaled and exhaled gas flow into electrical signals, and sends it to the signal processing circuit to complete the detection and display of inhaled and exhaled tidal volume, minute ventilation, and flow rate. For the diagnosis and treatment of medical personnel.
The ventilator has four main parameters: tidal volume, pressure, flow, and time. For GFS131 ventilator flow sensor, the short response time and large range of flow range can basically adapt to all ventilator.
In clinical application, the peak of inspiratory flow is mostly between 40-100L / min, so the peak of inspiratory flow of conventional ventilator is basically about 240L / min.
In clinical treatment, the patient's expiratory time, inspiratory time, respiratory rate, etc., all have corresponding index requirements. This requires that the flow sensor must have a short response time in order to control the patient's total breathing frequency, thereby monitoring the patient's treatment status. Generally, the response time of ventilator flow is less than 100ms.
