Abstract
The method is accomplished by introducing the catheter (20) into the organ such that the sampling chamber (40) is disposed at a portion of the wall of the organ. The sampling chamber (40) is left in position at the wall of the organ for a time sufficient to allow the fluid or gas of interest to diffuse into the sampling chamber (40). The concentration of the liquid fluid or gaseous fluid of interest is analyzed. The pH of the wall of the organ may be calculated based on the concentration of the fluid or gas property of interest.
