Definition
This is the best indicator for fluid balance
What is weight?
What is it considered when ph is normal but PaCO2 and HCO3 are not
what is fully compensated
Sodium range
135-145
This electrolyte is found mainly in intracellular fluid. It is key in maintaining cardiac function.
What is potassium?
An abnormal accumulation of interstitial fluid, or edema.
What is second spacing?
Dry mucous membranes, poor skin turgor, reported thirst, weak pulse, low BP
What is hypovolemia?
pH: 7.40
PaCO₂: 55 mmHg
HCO₃: 30 mEq/L
fully compensated respiratory acidosis
Potassium range
3.5-5
This is deposited in bone and plays a role in parathyroid hormone regulation
What is calcium?
Acids are excreted by this system
What is the kidneys/renal system?
Fluid leaking into the tissue, skin is cool and pale at site.
What is infiltration?
PaCO₂: 40 mmHg
HCO₃: 32 mEq/L
What is uncompensated metabolic alkalosis
Calcium range
8.5-10.5
Causes of this electrolyte imbalance include prolonged fasting, chronic alcoholism, and diarrhea
What is hypomagnesemia?
To determine acidosis or alkalosis, one would check this first.
What is pH?
Intravascular, interstitial, and transcellular fluids are this type of fluid.
What is extracellular fluid?
pH: 7.48
PaCO₂: 30 mmHg
HCO₃: 20 mEq/L
What is partially compensated metabolic alkalosis
Magnesium range
1.3-2.1
This can cause neurological deficits and in some cases seizures
what is hyponatremia?
A positive Chvostek's sign indicates this abnormality.
What is hypocalcemia?
Binds to proteins to get released into the cell
what is facilitated diffusion?
pH: 7.38
PaCO₂: 28 mmHg
HCO₃: 18 mEq/L
Fully compensated metabolic Acidosis
Normal pH
7.35-7.45
Sudden weight gain, tachycarcdia, distended jugular vein, edema, and crackles are signs of this.
What is hypovolemia
This red streak follows the vein and the skin is hot and inflammed.
What is phlebitis?
