Abstract
An artificial respiration apparatus includes a frame having a positive pressure input port, a negative pressure input port, an atmospheric port and an output port. A switching member switches between a first state in which the positive pressure input port is connected to the output port while the negative pressure input port is connected to the atmospheric port, and a second state in which the positive pressure input port is connected to the atmospheric port while the negative pressure input port is connected to the output port. A drive unit successively drives the switching operation of the switching member such that the connection between the negative pressure input port and the atmospheric port slightly precedes the connection between the positive pressure input port and the output port.
