In medicine, the mean arterial pressure (MAP) is an average calculated blood pressure in an individual during a single cardiac cycle. [1] Although methods of estimating MAP vary, a common calculation is to take one-third of the pulse pressure (the difference between the systolic and diastolic pressures), and add that amount to the diastolic pressure.
Examples of uses of the BSA: Renal clearance usually divided by the BSA i.e. per 1.73 m² to gain an appreciation of the true glomerular filtration rate (GFR); The Quetelet index uses a somewhat modified form of the BSA; The cardiac index is a measure of cardiac output divided by the BSA, giving a better approximation of the effective cardiac ...
Nomograms, e.g. a moving circular slide to calculate body surface area or drug dosages. A common class of algorithms are embedded in guidelines on the choice of treatments produced by many national, state, financial and local healthcare organisations and provided as knowledge resources for day to day use and for induction of new physicians.
Intensive care training is provided as a fellowship and is awarded as a Sub-Specialty certificate of Critical Care (Cert. Critical Care) which is awarded by the Colleges of Medicine of South Africa. Candidates are eligible to enter sub specialty training after completing specialty training in Anaesthetics, Surgery, Internal Medicine, Obstetrics ...
For example, gentamicin is an antibiotic that can be nephrotoxic (kidney damaging) and ototoxic (hearing damaging); measurement of gentamicin through concentrations in a patient's plasma and calculation of the AUC is used to guide the dosage of this drug. [3] AUC becomes useful for knowing the average concentration over a time interval, AUC/t.
Intensive care unit ICU patients often require mechanical ventilation if they have lost the ability to breathe normally.. An intensive care unit (ICU), also known as an intensive therapy unit or intensive treatment unit (ITU) or critical care unit (CCU), is a special department of a hospital or health care facility that provides intensive care medicine.
The calculation of the arterial and venous oxygen concentration of the blood is a straightforward process. Almost all oxygen in the blood is bound to hemoglobin molecules in the red blood cells. Measuring the content of hemoglobin in the blood and the percentage of saturation of hemoglobin (the oxygen saturation of the blood) is a simple ...
Minimum alveolar concentration or MAC is the concentration, often expressed as a percentage by volume, of a vapour in the alveoli of the lungs that is needed to prevent movement (motor response) in 50% of subjects in response to surgical (pain) stimulus.
