A blood gas test or blood gas analysis tests blood to measure blood gas tension values, it also measures blood pH, and the level and base excess of bicarbonate.The source of the blood is reflected in the name of each test; arterial blood gases come from arteries, venous blood gases come from veins and capillary blood gases come from capillaries.

This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic ...
Inadequate supply occurs, for example, with hypoperfusion as occurs in hemorrhagic shock. A rise in lactate out of proportion to the level of pyruvate, e.g., in mixed venous blood, is termed "excess lactate", and is an indicator of anaerobic glycolysis occurring in muscle cells, as seen during strenuous exercise. Once oxygenation is restored ...
An arterial blood gas (ABG) test, or arterial blood gas analysis (ABGA) measures the amounts of arterial gases, such as oxygen and carbon dioxide. An ABG test requires that a small volume of blood be drawn from the radial artery with a syringe and a thin needle , [ 1 ] but sometimes the femoral artery in the groin or another site is used.

Blood gas tension refers to the partial pressure of gases in blood. [1] There are several significant purposes for measuring gas tension. [ 2 ] The most common gas tensions measured are oxygen tension (P x O 2 ), carbon dioxide tension (P x CO 2 ) and carbon monoxide tension (P x CO). [ 3 ]
Full hematological adaptation to high altitude is achieved when the increase of red blood cells reaches a plateau and stops. The length of full hematological adaptation can be approximated by multiplying the altitude in kilometres by 11.4 days. For example, to adapt to 4,000 metres (13,000 ft) of altitude would require 45.6 days. [27]
3] is the concentration of bicarbonate in the blood [H 2 CO 3] is the concentration of carbonic acid in the blood; When describing arterial blood gas, the Henderson–Hasselbalch equation is usually quoted in terms of pCO 2, the partial pressure of carbon dioxide, rather than H 2 CO 3 concentration.
