Causes of respiratory alkalosis (7)
CNS-Lung-Metabolic-Meds:
Hypoxia
Parenchymal lung disease
Hyperventilation syndrome
Mechanical ventilation
CNS disorders
Metabolic disorders
Medications (salicylates, xanthines, catecholamines)
If respiratory alkalosis persists, how long before renal compensation?
What are the compensatory mechanisms? (2)
2-6 hours
Decrease H+ secretion (increases pH)
Increase HCO3 excretion (decrease bicarb)
By how much does plasma HCO3- decrease with the decrease in pCO2?
A 10 mmHg decrease in pCO2 causes a decrease of plasma HCO3- by 4 mEq/L
How much kcal/g in carbohydrates?
3.4 kcal/g
How much kcal/g in protein?
4 kcal/g
How much kcal/g in lipids?
9 kcal/g
