How does a nonrebreathing mask work? A one-way valve located between the reservoir bag and the base of the mask allows gas from the reservoir bag to enter the mask on inhalation but prevents gas in the mask from flowing back into the reservoir bag during exhalation. O It has a reservoir bag that must remain inflated during both inspiration and expiration. The nurse adjusts the oxygen flow to ensure that the bag does not collapse during inhalation. The mask is constructed in a way that allows a constant flow of room air blended with a fixed flow of oxygen. Excess gas leaves the mask through the two exhalation ports, carrying with it the exhaled carbon dioxide.

Vital capacity is defined as the: Group of answer choices maximum volume of air that can be moved into and out of the lungs during forced respiration. volume of air that can be forcibly exhaled after a normal inspiration. volume of air that can be forcibly exhaled at the end of a normal expiration. total volume of air contained in the respiratory passages.
