History of Artificial Ventilation | Winner-medi.com

 Ventilation, used to deliver supplemental oxygenation to respiratory-failing patients, is a crucial procedure. It was described ages ago, and since that time, techniques and devices used are continuously improving. Claudius Galenus was among the first to talk about lungs and ventilation almost 2000 years ago and since then, several scientists and philosophers have tried to understand this concept. At the middle of the 20th century, several unidirectional valves were developed with different characteristics. Many different manual ventilation methods were described and used including mouth-to-mouth and mouth-to-nose but the bag-valve-mask (BVM) technique remains the commonly used one in emergency situations and in prehospital settings. The original bag-valve-mask concept was developed in 1953 by the German doctor Holger Hesse and his partner Danish anesthetist Henning Ruben, following their initial work on a suction pump. Their resuscitator, named “Ambu”(Artificial Manual Breathing Unit), was manufactured and marketed in 1956 by their company.  Ambu now is the largest company who produces manual resuscitator especially the disposable ambu bag. Xiamen Winner is the leading manufacturer of ambu bag including reusable and disposable manual resuscitation bag in domestic China. These products have been exported to more than 80 countries and always receive favorable feedback.
