Respiratory Alkalosis
by Stephanie Hand
1. Pathophysiology
1.1. Metabolism of fats & Carbs = c02
1.2. Chemoreceptors in brain & periphery control H+ ions
1.2.1. senses increase
1.2.2. Tachypnea to "blow off" c02/H+
1.2.3. Hyperventilation continued = hypocapnia
1.3. Lungs blow off C02
1.3.1. Renal system eliminates bicarb (HC03) in alkaline urine
1.3.2. by doing this they save H+ ions in the body
1.4. Hypocapnia
1.4.1. Decreased serum K+ and P04- (intracellular shifts)
1.4.1.1. hypocalcemia
1.4.1.1.1. Decreased plasma membrane stabilit (increased /permeability)
1.4.1.2. hyponatremia
1.4.1.2.1. Hypoosmololity
1.4.1.3. hypophosphatemia
1.4.1.3.1. cellular use of Po4- for ATP formation
1.4.1.3.2. increased permeability
1.4.1.3.3. Decreased energy metabolism
1.4.1.3.4. decreased oxygenation to tissues
1.4.1.3.5. decreased platelet- risk for hemorrhage increased
1.5. If chronic: renal compensation keeps pH normal
2. Symptoms
2.1. Lethargy & Confusion
2.2. Anxiety
2.3. Nausea/vomiting
2.4. Hyperventilation
2.5. Seizures
2.6. Tachycardia
2.7. arhythmias
2.8. Numbness/tingling extremities
2.9. Tetany
2.10. Weakness
3. Definitions: Increased respiration's, decreased C02 levels, Increased blood pH levels
4. Causes
4.1. Hyperventilation
4.1.1. Panic disorder
4.1.1.1. Anxiety
4.2. Liver disease
4.3. Compensation for renal failure
4.4. Asthma
4.5. Mechanical ventilation
4.6. Hypermetabolism
4.6.1. Fever
4.6.2. Hyperthyroidism
