The invention relates to a method and device for measuring blood gas parameters, preferably pH, pCO2, and pO2, in a blood sample, where the blood sample of a patient is fed into at least one measuring cell of an analyzer. In order to obtain accurate values for the blood gas parameters even in cases where the temperature of the patient deviates from normal temperature, the temperature of the patient or blood sample is measured upon sample withdrawal, and the measured temperature is transmitted to the analyzer or is recorded by the analyzer, and the temperature of the measuring cell of the analyzer is adjusted to the measured temperature by cooling or heating.

What is claimed is: 1. A method for measuring blood gas parameters in a blood sample from a patient, comprising: measuring the temperature of the patient or the temperature of the blood sample upon sample withdrawal, feeding the blood sample into at least one measuring cell of an analyzer for measuring blood gas parameters, transmitting the measured temperature to the analyzer, adjusting the temperature of the at least one measuring cell of the analyzer to the measured temperature, wherein the analyzer enables entry of the sample only after the measuring cell is adjusted to the measured temperature, and measuring a blood gas parameter. 2. The method according to claim 1, wherein the measuring cell is adjusted to the measured temperature before the blood sample is entered into the analyzer. 3. The method according to claim 1, wherein the patient temperature is measured by a temperature probe adapted to be capable of being placed in or on the patient. 4. The method according to claim 3 wherein the temperature data are transmitted automatically to the analyzer. 5. The method according to claim 1, wherein the temperature of the measuring cell of the analyzer is adjusted between 22�� C. to 40�� C. 6. A method according to claim 1, wherein the transmission of the measured temperature to the analyzer is performed via cable, via IF signal, or via RF signal. 7. A method according to claim 1, wherein the measured blood gas parameter is at least one of pH, pCO2 , and pO2. 8. A method for measuring blood gas parameters in a blood sample from a patient, comprising: measuring the temperature of the patient or the temperature of the blood sample upon sample withdrawal, feeding the blood sample into at least one measuring cell of an analyzer for measuring blood gas parameters, transmitting the measured temperature to the analyzer, adjusting the temperature of the at least one measuring cell of the analyzer to the measured temperature, wherein the temperature of the patient is continuously measured and the temperature of the measuring cell is continuaVy adjusted synchronously with the temperature of the patient, and measuring a blood gas parameter. 9. The method according to claim 8, wherein the measuring cell is adjusted to the measured temperature before the blood sample is entered into the analyzer. 10. The method according to claim 8, wherein the patient temperature is measured by a temperature probe adapted to be capable of being placed in or on the patient. 11. The method according to claim 8, wherein the temperature data are transmitted automatically to the analyzer. 12. The method according to claim 8, wherein the temperature of the measuring cell of the analyzer is adjusted between 22�� C. to 40�� C. 13. The method according to claim 8, wherein the transmission of the measured temperature to the analyzer is performed via cable, via IF signal, or via RF signal. 14. The method according to claim 8, wherein the measured blood gas parameter is at least one of pH, PCO2, and PO2. 15. A method for measuring blood gas parameters in a blood sample from a patient, comprising: providing an analyzer including at least one measuring cell, adjusting the temperature of the sample to the temperature of the patient or the temperature of the blood sample upon sample withdrawal, wherein the analyzer enables entry of the blood sample only upon the measuring cell reaching the temperature of the patient or sample, and measuring a blood gas parameter. 16. The method of claim 15 wherein the blood sample is placed into at least one measuring cell. 17. The method of claim 15 wherein the temperature of the patient or sample is transmitted to the analyzer.
