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.
The machine was tested in clinical studies for the treatment of a broad range of medical conditions related to Intravascular Volume Status, such as anemia, [4] congestive heart failure, [5] sepsis, [6] CFS, [7] Hyponatremia, [8] Syncope [9] and more.
[2] 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.

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.
the physiologic response to a decrease in kidney perfusion is an increase in sodium reabsorption to control hyponatremia, often caused by volume depletion or decrease in effective circulating volume (e.g. low output heart failure). above 2% [citation needed] or 3% [2] acute tubular necrosis or other kidney damage (postrenal disease)
In general, hyponatremia is usually asymptomatic until severe. [10] Typical laboratory findings for tea and toast syndrome include a low serum osmolality (hypotonicity) with normal urine osmolality since antidiuretic hormone levels are normal. A common laboratory finding for the tea and toast phenomenon is manifestation as hyponatremia.
In an adrenal crisis, hypotension occurs due to low cortisol and volume depletion. [9] Hypovolemia might be resistant to vasopressors and fluids if it is not identified. In secondary adrenal insufficiency, hyponatremia results from decreased kidney excretion of electrolyte-free water and the inability to suppress vasopressin . [ 5 ]
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 ]
