Abstract
Embodiments are directed to a ventilation device and method to be used on a patient during CPR. In one embodiment, the ventilation device comprises a housing having at least one opening for interfacing with a patient's airway, at least one valve configured to permit outflow of respiratory gases/air from the airway to ambient, a release mechanism for opening and closing an inlet passage to permit inflow of respiratory gases/air to the airway, and a control device for controlling the opening/closing of the inlet passage.
Claims17
A ventilation device, comprising;
- a housing having at least one outlet passage and at least one inlet passage;
- at least one valve provided at the outlet passage configured to allow gas to flow out of the housing to ambient while inhibiting gas from entering through the outlet passage;
- at least one release mechanism provided at the inlet passage configured open and close to control inflow of gas through the inlet passage;
- and
- a control device operable to control the opening and closing of the release mechanism.
A method of providing ventilation to a patient's airway, comprising:
- positioning a ventilation device so that the ventilation device interfaces with the patient's airway;
- opening a valve to allow gas to flow out of the patient's airway while inhibiting gas from flowing into the patient's airways;
- and
- selectively opening and closing an inlet to control gas flow into the patient's airway.
