摘要：
The invention relates to a device for determining two or more respiratory parameters relating to an individual and a method for determining two or more respiratory parameters relating to an individual by means of the device. The disclosed device and method may be used in an individual suffering from pulmonary gas exchange problems relating to gas exchange of oxygen and/or carbon dioxide, e.g. a patient with chronic obstructive pulmonary disease. The device and method may also be used in a healthy individual or in an animal, e.g. for research experiments. The device has detection means for oxygen and carbon dioxide contents in inspired and expired gas and blood. The device is controlled by a computer with functionality for entering oxygenation, carbon dioxide and acid-base values from one or more blood samples from arterial, venous, central venous or mixed venous blood samples, and with the parameter estimation based on equations of gas exchange of both oxygen and carbon dioxide and equations describing the acid-base chemistry of blood potentially including the competitive binding of oxygen and carbon dioxide to hemoglobin.
