title: [Continuous mass-spectrometric measurement of CO2 while using a modified Mapleson D-(Bain-)system (author's transl)].
abstract: In 21 patients undergoing abdominal surgery a modified Mapleson D-(Bain-)system was used under controlled ventilation. An average endexpiratory CO2 of 40 mm Hg was measured at a flow of 70 ml/kg kontinuierlich registrierten endexspiratoritimes these values were stable. In some patients without evident metabolic disturbances we found the CO2 values at borderline or even pathologic. So an increased flow rate of 100 ml/kg is recommended.
