| Acid Base Balance1 | Connie Karvas, MSN, CFNP |
| Acid Base Balance2 | Regulation of Hydrogen ion concentration, Indicated by symbol "pH," power of hydrogen(H+), A solution is acidic, neutral or alkaline depending on number of hydrogen ions, Normal pH is 7.35-7.45, pH of 7.1 is acidic, pH of 7.5 is alkaline |
| Acid Base Balance3 | Acid-donate hydrogen ions (H+) donor, Base- accepts hydrogen ions-acceptor; forms hydroxyl ions (OH-) |
| Points to Make1 | Acid-Base Balance-H+ ion concentration of body fluids, Acid-any compound that donates H+ ions, Base-H+ ion acceptor, Cations-positively charged ions-H+, K+, Na+, Anions-negatively charged ions-Cl-, HCO3, Neutral- when positive and negative ions combine and form a neutral compound (NaCl) |
| Points to Make2 | pH-indicates H+ ion concentration in body fluids (acidity or alkalinity), pH- a scale of 0-14 with 7.4 being neutral |
| Defense Mechanisms | Buffer System- acts within seconds, Respiratory System- acts within 1-3 minutes, Renal System- requires several hours to days to act |
| Bicarbonate-Carbonic Acid System | 1st line of defense. One part acid to 20 parts base, H2CO3 1 HCO3 20 pH=7.4 CO2+H2O-H2CO3 carbon dioxide + water = carbonic acid H2CO3=CO2 + H2O lungs kidneys H2CO3 H+(+)HCO3 eliminated by kidneys |
| Respiratory System | 2nd line of defense, Lungs regulate H+ ion concentration by eliminating CO2, Excessive H2CO3 reduced in lungs to H2O & CO2, which is excreted in the lungs, Accomplished by adjusting rate & depth of ventilation, Lungs compensate for metabolic imbalances by retaining or removing CO2 |
