The first set of valves is a one-way valve located between the reservoir bag and the base of the mask.This valve allows gas flow to enter the mask from the reservoir bag when the patient inhales and prevents gas flow from the mask flowing back into the reservoir bag during the patient's exhalation.The second set of valves is at the exhalation ports.The one-way valves placed there prevent room air from entering the mask during inhalation.They also allow the patient's exhaled gases to exit the mask during exhalation.
