blood gas

n.
1. An analysis of the dissolved gases in blood plasma, including oxygen, nitrogen, and carbon dioxide.
2. Any of the gases that become dissolved in blood plasma.

blood gas

1 gas dissolved in the liquid part of the blood. Blood gases include oxygen, carbon dioxide, and nitrogen.
2 a laboratory test to determine oxygen, carbon dioxide, bicarbonate, and hydrogen ion (pH) concentrations in whole blood.

blood gas

A term that is variously defined as:
(1) Either of the major gases (CO2 and O2) in the blood.
(2) Blood gas analysis, see there.

blood gas

Clinical medicine
1. The major gases–CO2 and O2 in blood.
2. Blood gas analysis, see there.

gas

any elastic aeriform fluid in which the molecules are widely separated from each other and so have free paths.

alveolar gas
the gas in the alveoli of the lungs, where gaseous exchange with the capillary blood takes place. See also oxygen, carbon dioxide.
blood gas
gas bubble disease
a disease of fish in tanks in which the water is supersaturated with oxygen or nitrogen. Gas embolism develops in the gills. Air bubbles can be seen in the gills, eyes and under the skin and the fish show bizarre nervous behavior.
gas cap
a cap of gas above fluid or solid contents in a hollow viscus, e.g. in a static rumen. Seen radiologically in distended intestinal loops in paralytical ileus.
gas edema disease
gas exchange
gases move by simple diffusion in response to pressure differences; net diffusion occurs from areas of high pressure to areas of lower pressure irrespective of whether the gas is present as a gas or in solution or gases moving from gas to solution or vice versa. The rate of exchange of gases in body tissues, e.g. between alveolar space and erythrocyte, is influenced by many other factors, especially the diffusion distance and the solubility of the gas.
gas inhalation
irritant gases, e.g. manure gas, cause pulmonary edema.
laughing gas
nitrous oxide.
manure gas poisoning
see manure pit gas poisoning.
tear gas
a gas that produces severe lacrimation by irritating the conjunctivae. See lacrimator.
gas transport
relates to the efficiency of transport of gas, e.g. oxygen, by the patient as a whole. The efficiency of gas transport varies widely between normal individuals and between species, e.g. athletic breeds of horses and dogs have much faster gas transport systems than human athletes; the efficiency of gas transport in the individual depends largely on the rapidity of increase in minute ventilation, plus a similar rate of increase in cardiac output.
