Abstract
A carbon-dioxide sampling system for accurately monitoring carbon dioxide in exhaled breath. The system includes a ventilator. The ventilator is configured to ventilate a patient with respiratory gases. The ventilator includes a carbon-dioxide sampling control unit and a carbon-dioxide analyzer. The carbon-dioxide sampling control unit is configured to control the timing of sampling of carbon dioxide in the exhaled breath of a patient, and to control the timing of the analysis of exhaled gases by the carbon-dioxide analyzer.
