title: [The development of a CPU controlled COPD recovery training ventilator].
abstract: A COPD recovery training ventilator controlled by micro-computer is described. The paper include the design principles of emphasizing on the expiration help and reducing the FRC, stimulating phrenic nerve to strengthen inspiration and to lay up strength, stimulating abdominal muscle or pressing on abdomen to enhance expiration and make diaphragm relaxing thoroughly, four period synchronizing control mode and the hard and soft construction.
