Abstract
An infant ventilator is described of the type that switches between an inspiration phase during which gas under pressure is applied through a mouthpiece to cause involuntary inspiration of the infant to which the mouthpiece is coupled, and an expiration phase during which the infant is allowed to exhale or voluntarily inhale through the mouthpiece while gas flows past the mouthpiece. An overpressure relief system is included to monitor the pressure in the patient circuit and react to pressures above an operator-selected level by halting inflow of gas into the patient circuit, exhausting patient pressure to the atomsphere, and producing an alarm.
