On/Off control of oxygen flow when using a resuscitator bag:For use with hyperinflation bag (not included) weighing 3 ounces to 4 pounds (90-1814 grams). The use of these sizes of bags typically range from neonatal, pediatric to adult care. The valves are intended to be used with a flowmeter (not included) which controls the flow of oxygen to the valve.On/off oxygen action is controlled by lifting/replacing the bag on the arm of the valve. Immediate oxygen flow is provided when bag is lifted from the arm (preventing personnel from having to turn oxygen on). Oxygen flow is stopped when bag is replaced.
