mechanical and pneumatic valve percentage predicted control for ventilator for anesthesia

摘要

the valve percentage predicted in subject, by means of its cyclical operation, alternating between phases of inspiration and expiration, when used in a ventilator for anesthesia.in particular, the valve can be operated mechanically or pneumatically through a tree of command through the pressure in a chamber of commandthis room being held and ensuring no losses of gas in the environment.
