Subsequently, there has been development of respirator and, respectively. Since the use of equipment and force people to air pressure into the lungs until you adjust to using high pressure compressed air (Pneumatic drive) as a push to ventilator works without electricity at all, it is the Bird mark 7 was developed to use electric electric power using the AC power or battery power to help in the operation of the machine, for example, Bennett MA-I, Servo 900 3 PV – Emerson, or is working – mixed (mixed power) is used for both wind pressure and power sharing. Computer equipment is a major factor that causes the respirator performance and capability to rise a lot.
