Abstrakt: The effect of positive end expiratory pressure on the function of the Ayre's T-Piece System was studied using a simple lung model.Positive end expiratory pressure did not affect end tidal CO2during “controlled breathing” but caused an increase during “spontaneous breathing” when fresh gas flow was less than 3 times the minute volume. Gas dilution did not occur under any of the test conditions.
