Summary
Based on measurements of arterial CO2 tension in 132 adult patients, a curve was constructed relating fresh gas inflow and arterial CO2 tension for a modified Mapleson D system. In patients on controlled ventilation using a ventilating volume greater than the predicted respiratory minute volume, it was found that the arterial Pco2 can be predicted from the fresh gas inflow with an accuracy sufficient to be clinically useful.
Résumé
Nous basant sur la mesure du Pco2 artériel chez 132 adultes, nous avons établi une courbe de prédiction de la Paco2 par rapport au volume de gaz frais introduit dans un système Mapleson D modifié.
Chez ces malades sous respiration contrôlée avec des volumes de ventilation plus grands que les volumes-minute prédits, nous avons trouvé que les Paco2 peuvent être prédits avec assez de précision pour usage clinique à l’aide de notre courbe basée sur le volume de gaz frais administré.
