Web1 If either of unidirectional valves becomes incompetent, exhaled gas enters inspiratory limb. During the next inspiratory cycle, inspired gas will have a higher concentration of CO 2, hence producing a higher baseline inspiratory CO 2 2 Rebreathing CO 2 also occurs when CO 2 absorbent is depleted.
