摘要
There is disclosed a squeeze bag resuscitating device having an inhalation-exhalation valve with a gas supply to the squeeze bag that includes a proportionating valve which receives separate supplies of air and oxygen and which has a fixedly adjustable proportionating control member whereby the proportons of oxygen in the gas mixture can be fixedly adjusted to any of a plurality of preselected values. In a preferred embodiment, the proportionating valve is detachably mounted on the resuscitating device and can be interchanged with a demand valve such as that described in my prior U.S. Pat. No. 3,795,257.
