A manifold to measure exhaled tidal volume during high-frequency jet ventilation.
A simple manifold is described that enables accurate measurement of tidal volume and exhaled minute volume during high-frequency jet ventilation. The system was tested at zero end-expiratory pressure and during continuous positive airway pressure of up to 15 cm H2O, at jet drive pressures of up to 40 psig.
