Ventilator is a device that can replace, control or change normal physiological respiration of human beings, increase lung ventilation, improve respiratory function and save heart reserve capacity. Generally can be divided into non-invasive and invasive two categories. General patients can use non-invasive breathing machine, connected to the nose and mouth through the mask. If the therapeutic effect still cannot be achieved, invasive ventilator should be adopted, tracheal catheter should be inserted into the patient's airway through oral cavity or nasal cavity, or tracheal incision should be used for intubation to achieve therapeutic effect.
For the treatment of pneumonia, breathing machine is one of the most effective therapies in the absence of specific drugs. Wearing breathing machine can effectively improve blood oxygen of patients with pneumonia and reduce mortality. Academician Zhong Nanshan once pointed out in CCTV connection that nasal high-flow oxygen therapy and mechanical ventilation are currently one of the main methods for the treatment of pneumonia. According to the Associated Press, the Society of Critical Care Medicine estimates that 960,000 patients may need breathing machines during the pneumonia epidemic. In this new pneumonia epidemic,
"severe patients usually have respiratory failure symptoms. Respiratory failure will lead to anoxia, thus causing multiple organ failure. People will soon die. Through the use of external non-invasive and invasive breathing machines to assist breathing and ensure oxygen supply to brain and organs, we can survive the respiratory failure before carrying out subsequent treatment and observation. Ventilators help. " Zhao Weiguo said. Ma Xin, vice president of Huashan Hospital affiliated to Fudan University, said that the lungs of patients with new pneumonia would be obviously damaged, and the significance of breathing machine and artificial lung is very important at this time. "With the support of a ventilator, the patient's lungs can recover very well, which is of great significance to rescue critically ill patients and reduce the mortality rate.
