Hypoosmolar hyponatremia is a condition where hyponatremia is associated with a low plasma osmolality. [1] The term " hypotonic hyponatremia " is also sometimes used. [2] When the plasma osmolarity is low, the extracellular fluid volume status may be in one of three states: low volume, normal volume, or high volume.
Hyponatremia. Hyponatremia or hyponatraemia is a low concentration of sodium in the blood. [4] It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L ), with severe hyponatremia being below 120 mEq/L. [3] [8] Symptoms can be absent, mild or severe.
Hyponatremia, or low sodium, is the most commonly seen type of electrolyte imbalance. [7] [8] Treatment of electrolyte imbalance depends on the specific electrolyte involved and whether the levels are too high or too low. [3] The level of aggressiveness of treatment and choice of treatment may change depending on the severity of the disturbance ...
Moderate or severe hyponatremia, or hyponatremia with severe symptoms is treated by raising the serum sodium level by 1-2 mmol per liter per hour for the first few hours with a goal of raising levels less than 8-10 mmol per liter in the first 24 hours and 18 mmol per liter in the first 48 hours.

Hypoaldosteronism. Hypoaldosteronism is an endocrinological disorder characterized by decreased levels of the hormone aldosterone. Similarly, isolated hypoaldosteronism is the condition of having lowered aldosterone without corresponding changes in cortisol. [ 1] (. The two hormones are both produced by the adrenals .)
Isotonic hyponatremia. Isotonic hyponatremia is a form of hyponatremia with mOsm measured between 280 and 295. It can be associated with pseudohyponatremia, or with isotonic infusion of glucose or mannitol. [1]
The urine concentrations of sodium, chlorine and potassium may be used to investigate conditions such as abnormal blood electrolyte levels, acute kidney injury, metabolic alkalosis and hypovolemia. [1] [2] [3] Other electrolytes that can be measured in urine are calcium, phosphorus and magnesium. [4] Target. Lower limit.
An altered level of consciousness is any measure of arousal other than normal. Level of consciousness ( LOC) is a measurement of a person's arousability and responsiveness to stimuli from the environment. [1] A mildly depressed level of consciousness or alertness may be classed as lethargy; someone in this state can be aroused with little ...
