blood gases (redirected from capillary blood gases)
blood gas·es (blŭd gas'ĕz)
A clinical expression for the determination of the partial pressures of oxygen and carbon dioxide in blood.
blood gases normally refers to the oxygen and carbon dioxide that are dissolved in the arterial blood, following equilibration in the lungs between capillary blood and the gases in the alveoli. Measured as part of the assessment of lung function; expressed as partial pressures (or 'tensions') P O2 and P CO2. There is also a small amount of dissolved nitrogen, at a P N2 in equilibrium with alveolar nitrogen. See also hypoxia, hypercapnia, oxyhaemoglobin dissociation curve.
