An ECG in a person with a potassium level of 1.1 meq/L showing the classical changes of ST segment depression, inverted T waves, large U waves, and a slightly prolonged PR interval. Hypokalemia is a low level of potassium (K +) in the blood serum. [1] Mild low potassium does not typically cause symptoms. [3]
Exercise can cause a release of potassium into bloodstream by increasing the number of potassium channels in the cell membrane. The degree of potassium elevation varies with the degree of exercise, which range from 0.3 meq/L in light exercise to 2 meq/L in heavy exercise, with or without accompanying ECG changes or lactic acidosis.
An equivalent (symbol: officially equiv; [1] unofficially but often Eq[2]) is the amount of a substance that reacts with (or is equivalent to) an arbitrary amount (typically one mole) of another substance in a given chemical reaction. It is an archaic quantity that was used in chemistry and the biological sciences (see Equivalent weight § In ...
“It appears that maintaining normal potassium levels (> 3.6 mEQ/L) is all that is needed and that there is no benefit for trying to maintain that higher level at 4.5 mEQ/L,” Drury noted.
“Potassium (along with other electrolytes such as calcium and sodium and magnesium) are involved in the electrical functions of cardiac cells and the ‘normal range’ between 3.5 and 4.5 mEq/L ...
Potassium resides mainly inside the cells of the body, so its concentration in the blood can range anywhere from 3.5 mEq/L to 5 mEq/L. [9] The kidneys are responsible for excreting the majority of potassium from the body. [9] This means their function is crucial for maintaining a proper balance of potassium in the blood stream.
The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. The equivalent weight of an element is the mass of a mole of the element divided by the element's usual valence. That is, in grams, the atomic weight of the element divided by the usual ...
v. t. e. Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry ...
