Abstract
Methods and apparatus for determining the difference between a regional CO,partial pressure of a selected body organ of a mammalian subject, such as the gut, and a systemic CO,partial pressure of the subject. The regional CO,partial pressure value is tonometrically obtained at body temperature using a gaseous sampling medium. A systemic CO,partial pressure value is obtained from the blood. The systemic CO,partial pressure value can be that for the body temperature or for a standard temperature. If the systemic CO,partial pressure value is that for the body temperature, the regional CO,partial pressure value is compared to the systemic CO,partial pressure value and the difference therebetween is provided as a CO,partial pressure gap measurement. If the systemic CO,partial pressure value is that for a standard temperature, one of the regional CO,partial pressure value or the systemic CO,partial pressure value is corrected for the difference between the body temperature and the standard temperature so that both the partial pressure values comprise CO,partial pressure values at a common temperature. The values are thereafter compared to provide a CO,partial pressure gap measurement. An end tidal CO,partial pressure value may be used as the systemic CO,partial pressure value.
