  • 1. ACID/BASE BALANCE INDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com www.indiandentalacademy.com
  • 2. ACIDS, BASES AND SALTS CHEMICAL COMPOUNDS CAN BE PROTON DONORS OR ACCEPTORS PROTON DONORS ARE ACIDS PROTON ACCEPTORS ARE BASES ACIDS AND BASES REACT TO NEUTRALIZE EACH OTHER FORMING SALTS www.indiandentalacademy.com
  • 3. ACID/BASE REACTIONS HCl + NaOH NaCl + H2O ACID + BASE SALT + WATER www.indiandentalacademy.com
  • 4. ACID/BASE BALANCE AND THE BLOOD [OH -] [H+] Acidic Alkaline (Basic) Neutral pH 0 Venous Blood Acidosis 6.8 7 7.4 Normal 7.35-7.45 www.indiandentalacademy.com 14 Arterial Blood Alkalosis 8.0
  • 5. CHEMICAL BUFFER SYSTEMS Unbuffered Salt Solution Na+ Add HCl ClCl- Protons taken up as Carbonic Acid H2CO3: HCO3- Buffer HCO3H+ H+ Na+ Cl- H2CO3 All protons are free H2CO3 Add HCl HCO3www.indiandentalacademy.com + H+
  • 6. CHEMICAL BUFFER SYSTEMS Weak acid/salt systems act as a “sponge” for protons As acidity tends to increase they take protons up As acidity tends to decrease they release protons www.indiandentalacademy.com
  • 7. CHEMICAL BUFFER SYSTEMS Carbonic acid/Bicarbonate: Primary buffer against non-carbonic acid changes Proteins: Primary ICF buffer, also ECF Hemoglobin: Primary buffer against carbonic acid changes Phosphate: Urinary buffer, also ICF www.indiandentalacademy.com
  • 8. ROLE OF RESPIRATORY SYSTEM IN ACID/BASE BALANCE Alterations in ventilation alter the rate of excretion of carbon dioxide Alterations in the rate of carbon dioxide excretion cause alterations in pH through carbonic acid This way the respiratory system can help control non-respiratory acidosis and alkalosis www.indiandentalacademy.com
  • 9. Sources of acidosis Metabolic: Severe diarrhea, Diabetes mellitus, strenuous exercise, uremia Respiratory: hypoventilation www.indiandentalacademy.com
  • 10. Sources of alkalosis Metabolic: Vomiting, ingestion of alkaline drugs Respiratory: hyperventilation www.indiandentalacademy.com
  • 11. Renal regulation of blood acidity Proton excretion Bicarbonate excretion Ammonia secretion www.indiandentalacademy.com
