  2. Electrolyte imbalance - Wikipedia

    en.wikipedia.org/wiki/Electrolyte_imbalance

    If a person has high total body water (such as due to heart failure or kidney disease) they may be placed on fluid restriction, salt restriction, and treated with a diuretic. [3] If a person has a normal volume of total body water, they may be placed on fluid restriction alone. [3]

  3. Fractional excretion of sodium - Wikipedia

    en.wikipedia.org/wiki/Fractional_excretion_of_sodium

    Fractional excretion of other substances can be measured to determine kidney clearance including urea, uric acid, and lithium. These can be used in patients undergoing diuretic therapy, since diuretics induce a natriuresis. Thus, the urinary sodium concentration and FE Na may be higher in patients receiving diuretics in spite of prerenal ...

  4. Error correction model - Wikipedia

    en.wikipedia.org/wiki/Error_correction_model

    Several methods are known in the literature for estimating a refined dynamic model as described above. Among these are the Engle and Granger 2-step approach, estimating their ECM in one step and the vector-based VECM using Johansen's method.

  5. Fluid balance - Wikipedia

    en.wikipedia.org/wiki/Fluid_balance

    If fluid loss is greater than fluid gain (for example if the patient vomits and has diarrhea), the patient is said to be in negative fluid balance. In this case, fluid is often given intravenously to compensate for the loss. On the other hand, a positive fluid balance (where fluid gain is greater than fluid loss) might suggest a problem with ...

  6. Renal compensation - Wikipedia

    en.wikipedia.org/wiki/Renal_compensation

    Kidneys within the human body, where renal compensation takes place. Renal compensation is a mechanism by which the kidneys can regulate the plasma pH.It is slower than respiratory compensation, but has a greater ability to restore normal values.

  7. Intravascular volume status - Wikipedia

    en.wikipedia.org/wiki/Intravascular_volume_status

    Renal causes include overuse of diuretics, or trauma or disease of the kidney. Extrarenal causes include bleeding, burns, and any causes of edema (e.g. congestive heart failure, liver failure). [citation needed] Intravascular volume depletion is divided into three types based on the blood sodium level:

    en.wikipedia.org/wiki/Non-random_two-liquid_model

    VLE of the mixture of chloroform and methanol plus NRTL fit and extrapolation to different pressures. The non-random two-liquid model [1] (abbreviated NRTL model) is an activity coefficient model introduced by Renon and Prausnitz in 1968 that correlates the activity coefficients of a compound with its mole fractions in the liquid phase concerned.

  9. Calcium pump - Wikipedia

    en.wikipedia.org/wiki/Calcium_pump

    Calcium pumps are a family of ion transporters found in the cell membrane of all animal cells. They are responsible for the active transport of calcium out of the cell for the maintenance of the steep Ca 2+ electrochemical gradient across the cell membrane.
