standard bicarbonate


Also found in: Dictionary, Thesaurus, Legal, Encyclopedia.

stan·dard bi·car·bon·ate

the plasma bicarbonate concentration of a sample of whole blood that has been equilibrated at 37°C with a carbon dioxide pressure of 40 mm Hg and an oxygen pressure that exceeds 100 mm Hg; abnormally high or low values indicate metabolic alkalosis or acidosis, respectively.

standard bicarbonate

the bicarbonate ion concentration of plasma separated anaerobically from whole blood that has been saturated with oxygen and equilibrated at carbon dioxide pressure of 40 torr at 100° F (38° C). It is a measure of the metabolic disturbance of acid-base balance in a sample of blood after the correction of any respiratory disturbance.

stan·dard bi·car·bo·nate

(stan'dărd bī-kahr'bŏn-āt)
The plasma bicarbonate concentration of a sample of whole blood that has been equilibrated at 37°C with a carbon dioxide pressure of 40 mmHg and an oxygen pressure greater than 100 mm Hg; abnormally high or low values indicate metabolic alkalosis or acidosis, respectively.

standard

something established as a measure or model to which other similar things should conform.

bacteriological standard of meat
the standard bacterial count of meat beyond which local legislation forbids the sale or use of meat. The international standard is for <107 of="" meat="" and="" that="">Salmonella spp. should not be present in more than one of five 25 g samples, all held at 95°F (35°C) or 68°F (20°C) for chilled meat.
standard bicarbonate
in blood gas analysis this is the plasma level of bicarbonate, under specified conditions, which eliminates the influence of respiration on the values obtained.
standard deviation
a measure of the dispersal of a random variable; the square root of the average squared deviation from the mean. For data that have a normal distribution about 68% of the data points fall within one standard deviation from the mean and 95% fall within two standard deviations. Symbol is σ.
standard error
the standard deviation of an estimate.
standard error of mean
the sampling variability of the mean.
standard international (SI) units
see Table 3.
standard population
a population not yet divided into classes; the population against which each of its constituent classes can be compared.
standard Salmonella pullorum strains
strains that contain only small amounts of 122 antigen.
