The test uses only the fluid in your blood, not the blood cells or the platelets that help yourblood clot. A lab technician will add acid to the liquid to unlock carbon dioxide from the bicarbonate. The amount of bicarbonate is measured by how fast the sample’s acidity changes. Reading ...
Determination of membrane potentials in human andAmphiuma red blood cells by means of a fluorescent probe 1. Changes in the fluorescent intensity of the dye, 3,3'-dihexyl-2,2'-oxacarbocyanine, added to suspensions of human and Amphiuma red blood cells were measured in parallel with changes in...
Attention is drawn to the steepening of the CO 2 dissociation curve of sea water in the range of physiological, low CO 2 pressures, attributable to buffering. Some general relationships between the slopes of the O 2 and CO 2 dissociation curves of blood, the effective solubility in sea ...
