Abstract
A system is disclosed to prevent the build up of pressure within a patient circuit when an oxygen flush is activated in a ventilator powered anesthesia system. In the event the user activates the oxygen flush at a time that the ventilator is in the inhalation cycle providing a breath to the patient, a valve is automatically opened to vent the patient circuit to the atmosphere, thereby preventing that additional oxygen flow to the patient circuit from resulting in an undesirable pressure build up that could affect the lungs of the patient.
