Abstract
A resuscitation valve assembly includes a housing with an inlet port adapted to be connected to a pressurized breathable gas source, such as oxygen, an outlet port adapted to be connected to a patient's airway and an ambient air port. The inhalation chamber is connected to the pressurized gas source when a manually operated valve, within the housing, is open and is disconnected from the inhalation chamber when the valve is closed. An inhalation/exhalation check valve is disposed between the inhalation chamber, the outlet port and the ambient air port to conduct the high pressure gas through the outlet port and into the patient's airway, vent the patient's exhaled gas through the ambient air port and allow ambient air to flow through the outlet port in response to the patient's spontaneous breathing.
