Urine-blood carbon dioxide tension gradient in healthy dogs

1991

Shaw, D.H.

The urine-blood carbon dioxide tension (PCO2) gradient was measured in 10 healthy mature Beagles after alkalinization of the urine by administration of sodium bicarbonate. The mean (+/- SD) urine-blood PCO2, gradient was 65.92 +/- 14.42 mm of Hg, with range of 38.2 to 82.2 mm of Hg. Mean urine PCO2, was 110.21 +/- 14.19 mm of Hg, with range of 84.1 to 127.3 mm of Hg. Because urine-blood PCO2 gradient < 30.0 mm of Hg or urine PCO2 < 55 mm of Hg in people is diagnostic for a defect in distal nephron acidification, similar values might be applicable to diseases in dogs.
