Abstract
In a method for operating a respiratory gas analysis device with at least one gas sensor, once a respiratory gas analysis has been carried out, the gas sensor is heated to a temperature that lies above a predefinable temperature threshold value.
Claims11
A method for operating a respiratory gas analysis device having at least one gas sensor, comprising:
- after carrying out a respiratory gas analysis, heating the gas sensor to a temperature above a specifiable temperature threshold value,
- wherein the heating includes:
- evaluating whether each termination criteria of at least one termination criteria is met in connection with the temperature of the gas sensor, a purge gas stream conducted over the gas sensor, or an electrical voltage applied across the gas sensor;
- and
- terminating the heating in response to each of the termination criteria being met.

A respiratory gas analysis device comprising:
- at least one gas sensor configured to carry out a respiratory gas analysis and, after the respiratory gas analysis, the respiratory gas analysis device is configured to heat the at least one gas sensor to a temperature above a specifiable temperature threshold value,
- wherein during the heating, the respiratory gas analysis device is configured to:
- evaluate whether each termination criteria of at least one termination criteria is met in connection with the temperature of the gas sensor, a purge gas stream conducted over the gas sensor, or an electrical voltage applied across the gas sensor;
- and
- terminate the heating in response to each of the termination criteria being met.
