LOINC. 5639-0, 5640-8, 15120-9, 56478-1. Blood alcohol content ( BAC ), also called blood alcohol concentration or blood alcohol level, is a measurement of alcohol intoxication used for legal or medical purposes. [ 1] BAC is expressed as mass of alcohol per volume of blood.
The concentration of alcohol in blood is measured via blood alcohol content (BAC). The amount and circumstances of consumption play a large role in determining the extent of intoxication; for example, eating a heavy meal before alcohol consumption causes alcohol to absorb more slowly. [ 1 ]
The blood alcohol content (BAC) for legal operation of a vehicle is typically measured as a percentage of a unit volume of blood. This percentage ranges from 0.00% in Romania and the United Arab Emirates; to 0.05% in Australia, South Africa, Germany, Scotland, and New Zealand (0.00% for underage individuals); to 0.08% in England and Wales , the ...
The patient should remain in the ice bath until their body temperature falls to 102.2 degrees. Then, they can be transported to the hospital. Preparing for heat illness in a warming world
Medical thermometer. Clinical thermometer. A medical/clinical mercury thermometer showing the temperature of 37.7 °C (99.9 °F) Purpose. Measures body temperature. A medical thermometer or clinical thermometer is a device used for measuring the body temperature of a human or other animal. The tip of the thermometer is inserted into the mouth ...
The physical limitation of the ability of a thermometer to measure low temperature is the freezing point of the liquid used. Ethanol freezes at −114.9 °C (−174.82 °F). If an alcohol thermometer utilizes a combination of ethanol, toluene, and pentane, its lower temperature range may be extended to measure temperatures down to as low as − ...
The major form of thyroid hormone in the blood is thyroxine (T 4), whose half-life of around one week [4] is longer than that of T 3. [5] In humans, the ratio of T 4 to T 3 released into the blood is approximately 14:1. [6] T 4 is converted to the active T 3 (three to four times more potent than T 4) within cells by deiodinases (5′-deiodinase).
In any case, the concentration of T 3 in the human blood plasma is about one-fortieth that of T 4. The half-life of T 3 is about 2.5 days. [3] The half-life of T 4 is about 6.5 days. [4] T 3 levels start to rise 45 minutes after administration and peak at about 2.5 hours.
