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 ...
out by taking a quantity of acid, for example lactic acid into the syringe, coupling the syringe and vial, depressing the plunger to add the acid to the blood sample, shaking the coupled assembly and allowing the plunger to rise under the pressure of the carbon dioxide released in the vial...
In this system, carbon dioxide diffuses into the red blood cells. Carbonic anhydrase (CA) within the red blood cells quickly converts the carbon dioxide into carbonic acid (H2CO3)(H2CO3). Carbonic acid is an unstable intermediate molecule that immediately dissociates into bicarbonate ions (HCO...
Figure 1. Most of carbon dioxide is transported in the blood as bicarbonate anions, which are formed from the catalysis of carbon dioxide and water by carbonic anhydrase to form carbonic acid. The carbon dioxide-hemoglobin dissociation curve The various forms of carbon dioxide in the blood cre...
roomtemperature, it's a gas with no taste or smell. CO2 can also be found in solid form, commonly known as dry ice. Humans naturally breathe in some carbon dioxide that's in the atmosphere. The functioning cells in your body also create carbon dioxide, and you breathe it out when you...

Method for assaying CO2 and HCO3- in biological fluids, esp. whole blood, plasma or serum, comprises adding phosphoenalpyruvate (I) and an enzyme catalyst (II) (phosphoenolpyruvate carboxylase (pref.) or phosphoenolpyruvate carboxybinase) so that (I) and HCO3- react to form oxalacetate (III)...

The carbon dioxide transfer rate in blood near venous conditions was about twice that of inert gas, a rate significantly greater than predicted by the local equilibrium theory. It should be possible to apply these theoretical methods to predict exchange rates with blood flowing in systems of other...
In the first place it is evident that the bloods of the more highly developed marine invertebrates, such as the active Crustacia and the Cephalopods, are specially adapted for the carriage of carbon dioxide. The quantity of carbon dioxide taken up by the blood of Maia, Palinurus, or Octopus...
