The Life-support machine is one of the most important technological inventions of the 19th century. Over the centuries, after several generations of experiments and clinical explorations, it has been improved to the present. Throughout the history of human medicine, the evolution of the ventilator has gone through the following three stages: The establishment phase of a manual ventilation theory (before the ventilator was invented); Two negative pressure ventilation stages (the ventilator was invented at the beginning of manufacture); Three positive pressure ventilation phase (after the ventilator is gradually improved). 　 According to statistics, the current market share of manufacturers in the ventilator market is as follows: The following are the main manufacturers of ventilators: 1, Dräger Dräger is an international pioneer in medical and safety technology. Founded in Lübeck in 1889, Dräger has been a family-run company that has gone through the fifth generation, went global and was included in the DAX index. Its medical division's product portfolio covers anesthesia workstations, respiratory ventilation devices for intensive care and home therapy, emergency and transport breathing devices, infant thermal therapy devices , patient monitoring devices, IT solutions and gas management systems. Evita 2 dura is a high-end ventilator from Dräger, a simple and versatile ventilator for intensive care units. Highly sensitive flow rate triggering and an open breathing system provide the concept of “open ventilation†for patients and users. The color screen provides powerful ventilation monitoring. Self-breathing maintains a high functional residual volume, thereby reducing the risk of atelectasis and improving the ventilation/perfusion ratio so that the patient can breathe spontaneously at any time. Evita 2 dura is suitable for every patient.
