What will ionize almost completely in an aqueous solution?
What will ionize only to a small extent?
Weak acid or base
What are the buffer systems?
- "OBE": Open, Bicarbonate, Erythrocyte and Plasma
- "CNH": Closed, Nonbicarbonate, Hemoglobin/Organic phosphates/Inorganic phosphates/Plasma Proteins
How does the Henderson-Hasselbalch Equation look at pH?
- the biologic acid-base relationship by looking at one specific component of the system, namely the carbonic acid (H2CO3) to bicarbonate ion (HCO3) relationship
- it is expressed at have Bicarbonate (kidneys) in the numerator, and CO2 (lungs) in the denominator
What is the following blood gas: pH = 7.25, PaCO2 = 55, Bicarbonate = 20, BD = -4
Mixed Respiratory and Metabolic Acidosis
In respiratory acidosis (hypoventilation), what will the kidneys do?
restore pH by reabsorbing bicarbonate
In respiratory alkalosis (hyperventilation), what will the kidneys do?
eliminate Bicarbonate throuhg urine
In metabolic acidosis what will the lungs do?
In metabolic alkalosis what will the lungs do?
What is the normal Anion Gap range?
Is potassium (K+) taken into account when calculating anion gap?
no, too small
What does iatrogenic result from?
the use of diuretics, low-salt diets, and gastric drainage
