Acid Bases Part3 RESP 132
RESP 132 Aicd - Bases
The loss of cholride, potassium, and fluid volume may cause?
Its this organ's job to reabsorb sodium because sodium has a major role in maintaing fluid balance.
is a mothod in which sodium is reasbsorbed out from the renal tubule cell into the blood.
Primary Active Transport
Done by the kidney, allows for exchange of Na+(reabsorption of Na+)
Secondary active secretions of H+ and K+
Compensaory responce is hypoventilation (CO2 retained) when this is happening.
The correction of this disorder is restoring normal fluid volume and electolyte % (esp. K+ and Cl- levels). Treat w/KCL(hypokalemia), dilute HCl- or NH4Cl- in sever cases
is defined as the plasma concentration of HCO3 in mEq/L that would exist ( at body temperature) with a normal PCO2 od 40mmHg.
Standard Bicarbonate eliminates the effect of dissolved ____________ levels (hydration RXN) thereby allows one to assess strictly the metabolis component of acid-base balance.
CO2 on HCO3-
indicator of metabolic acid-base disturbances. Helps fine tune analysis when compensation or mixed disorders occur. done by equilibrating blood sample in the las to a PCO2 of 40mmHg at BT 37 degrees
Base Excess ( Base Deficit)
Positive BE > +2 indicates?
gain of base or loss of acid
Negative BE < -2 indicates?
a loos of base or gain of acid
A change in BE/BD shows __________, it could be primary or it could be compensation.
In acute respiratory acidosis, the BE/BD would be ________. This idicates that the pH change is purely respiratory.
In compensated respiratory acidosis, the BE will ________.
This is determined by multiplying the extracellular fluid volume by the base deficit in mEq/L from ABG
Total Body deficit
To estimate an individual's extracellular fluid volume in leters you need to?
Take 1/4 of the body weight in kg.
Normally NaHCO3- is administered only in the case of severe__________.
This is defined as a base deficit of a 10mEq/L and one of the follow inf exist: a pH <7.20 or a pH between 7.20 and 7.25 with an unstable cardiovascular system.
Severe metabolic acidosis
if the base deficit is 10mEq/L and the pH is > 7.25 do you give NaHCO3-?
This is due to a change in both metabolic and respiratory parameters changing in opposite directions.
Mixed acid-Base (ex. Acidosis: CO2 increases HCO3 decreases)
both resp. and meta. exist. both promoting the same acid-base disturbance.
