Blood gas test

Index Blood gas test

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. [1]

Acidosis

Acidosis is a process causing increased acidity in the blood and other body tissues (i.e., an increased hydrogen ion concentration).

Arterial blood

Arterial blood is the oxygenated blood in the circulatory system found in the pulmonary vein, the left chambers of the heart, and in the arteries.

Arterial blood gas test

An arterial-blood gas (ABG) test measures the amounts of arterial gases, such as oxygen and carbon dioxide.

Artery

An artery (plural arteries) is a blood vessel that takes blood away from the heart to all parts of the body (tissues, lungs, etc).

Base excess

In physiology, base excess and base deficit refer to an excess or deficit, respectively, in the amount of base present in the blood.

Bicarbonate

In inorganic chemistry, bicarbonate (IUPAC-recommended nomenclature: hydrogencarbonate) is an intermediate form in the deprotonation of carbonic acid.

Blood

Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.

Blood gas tension

Blood gas tension refers to the partial pressure of gases in blood.

Blood lancet

A blood lancet, or simply lancet, is a small medical implement used for capillary blood sampling.

Blood test

A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick.

Capillary

A capillary is a small blood vessel from 5 to 10 micrometres (µm) in diameter, and having a wall one endothelial cell thick.

Capillary action

Capillary action (sometimes capillarity, capillary motion, capillary effect, or wicking) is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity.

Diabetic ketoacidosis

Diabetic ketoacidosis (DKA) is a potentially life-threatening complication of diabetes mellitus.

New!!: Blood gas test and Diabetic ketoacidosis · See more »

Lactic acidosis

Lactic acidosis is a medical condition characterized by the buildup of lactate (especially L-lactate) in the body, which results in an excessively low pH in the bloodstream.

New!!: Blood gas test and Lactic acidosis · See more »

Medical diagnosis

Medical diagnosis (abbreviated Dx or DS) is the process of determining which disease or condition explains a person's symptoms and signs.

New!!: Blood gas test and Medical diagnosis · See more »

Metabolic acidosis

Metabolic acidosis is a condition that occurs when the body produces excessive quantities of acid or when the kidneys are not removing enough acid from the body.

Neonatal encephalopathy

Neonatal encephalopathy (NE), also known as neonatal hypoxic-ischemic encephalopathy (neonatal HIE or NHIE), is defined by signs and symptoms of abnormal neurological function in the first few days of life in an infant born at term.

Oxygen saturation

Oxygen saturation (symbol SO2) is a relative measure of the concentration of oxygen that is dissolved or carried in a given medium as a proportion of the maximal concentration that can be dissolved in that medium.

New!!: Blood gas test and Oxygen saturation · See more »

Partial pressure

In a mixture of gases, each gas has a partial pressure which is the hypothetical pressure of that gas if it alone occupied the entire volume of the original mixture at the same temperature.

New!!: Blood gas test and Partial pressure · See more »

PCO2

The pCO2, PCO2, p_\ceor P_\ce is the partial pressure of carbon dioxide (CO2), often used in reference to blood, but also used in oceanography to describe the partial pressure of CO2 in the Ocean, and in life support systems engineering and underwater diving to describe the partial pressure in a breathing gas.

Radial artery puncture

Radial artery puncture is a medical procedure performed to obtain a sample of arterial blood for gas analysis.

Respiration (physiology)

In physiology, respiration is defined as the movement of oxygen from the outside environment to the cells within tissues, and the transport of carbon dioxide in the opposite direction.

New!!: Blood gas test and Respiration (physiology) · See more »

Respiratory acidosis

Respiratory acidosis is a medical emergency in which decreased ventilation (hypoventilation) increases the concentration of carbon dioxide in the blood and decreases the blood's pH (a condition generally called acidosis).

New!!: Blood gas test and Respiratory acidosis · See more »

Respiratory alkalosis

Respiratory alkalosis is a medical condition in which increased respiration elevates the blood pH beyond the normal range (7.35–7.45) with a concurrent reduction in arterial levels of carbon dioxide.

New!!: Blood gas test and Respiratory alkalosis · See more »

Vein

Veins are blood vessels that carry blood toward the heart.

Venipuncture

In medicine, venipuncture or venepuncture is the process of obtaining intravenous access for the purpose of intravenous therapy or for blood sampling of venous blood.

New!!: Blood gas test and Venipuncture · See more »

Venous blood

Venous blood is deoxygenated blood which travels from the peripheral vessels, through the venous system into the right atrium of the heart.
