ABSTRACT:
The invention is directed to a multi-stage mouth-to-mouth resuscitation valve in combination with a first valve to allow exhaled breath from a mouth of an operator to pass through the first valve to a mouth of a victim. The first valve is capable of assuming a position where exhaled breath of the victim can escape from the multi-stage resuscitation valve.
A second valve is provided to ensure that exhaled breath of a victim which may leak by the first valve does not reach the mouth of the operator. The second valve is positioned between the first valve and the mouth of operator.
