Web(B) An incompetent inspiratory valve causes some rebreathing, because exhaled gas flows into the inspiratory limb, which is small. On inspiration, end-tidal gas is re-inhaled, followed by fresh gas. The result is a long expiratory capnogram, a normal inspired CO 2, and a … WebIncompetent Inspiratory Valve -there's a decreased slope during inspiratory phase (widened beta angle). Part of the exhaled breath re-enters the inspiratory limb, so the patient re-breathes some of the previously exhaled CO2 on the next breath -the waveform may or may not reach zero depending on the FGF •Not returning to zero axis
