ABSTRACT:
An improved artificial ventilator is capable of selection or setting of any arbitrary pattern or waveform of the flow rate of inspiration gas. The flow rate of inspiration gas is controlled through an inspiration valve according to an input representative of a flow rate pattern of an inspiration gas with the aid of a micro-computer, whereby a desired flow pattern of inspiration gas is optionally set.
