Incompetent inspiratory valve
WebWhen the inspiratory unidirectional valve in the circle system is incompetent, exhaled gases enter the inspiratory limb of the circuit (Figure 2) and during the next inspira- tion, enter the lungs to produce prolonged CO 2 plateau. These events result in a characteristic capnogram com- prising an apparently shorter inspiratory phase and a ... WebThe expiratory unidirectional valve was noted to be fixed in the open position and thus allowing previously exhaled gases, high in CO2, to be rebreathed with each inspiration. The CO2 waveform returned to normal soon after the valve was removed, cleaned, dried, and replaced. Reference Pyles, ST, Berman LS, Modell JH.

WebIncompetent inspiratory or expiratory valves will reduce the efficiency of gas circulation and result in rebreathing and consequent carbon dioxide retention. Some machines are equipped with valves made of deformable rubber: As the rubber ages, these discs tend to harden in a semi-open position, again allowing the valve to become incompetent. 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
