Single-breath CO diffusing capacity influenced by initial alveolar partial pressure of CO

The purpose of this study was to assess the influence of incorrect determinations of the initial alveolar partial pressure of carbon monoxide (CO) at the beginning of breath holding (PIAco) on the pulmonary CO diffusing capacity of the lung (DLco). Single-breath maneuvers were performed on 14 anesth...

Description
Summary:The purpose of this study was to assess the influence of incorrect determinations of the initial alveolar partial pressure of carbon monoxide (CO) at the beginning of breath holding (PIAco) on the pulmonary CO diffusing capacity of the lung (DLco). Single-breath maneuvers were performed on 14 anesthetized and artificially ventilated rabbits, using 0.2% CO in nitrogen as the indicator gas mixture.
