Brain-blood partition coefficients of 85Krypton at 37 C and 29.5 C.
To permit utilization of the Kety-Schmidt technique for measuring cerebral blood flow during hypothermia, the brain-blood partition coefficients for 85krypton at 37 C and 29.5 C were determined in a series of cats. At 37 C the partition coefficient for 85krypton was 1.092 +/- 0.009; it was 0.931 +/- 0.007 (SE) at 29.5 C. These values were significantly different from each other (P less than .001).
