Terms | Definitions |
|---|---|
 Acid | Substance that release H+ in solution (body fluids). |
| Base | Hydroxyl ion (OH-) or bicarbonate ion (HCO3-) substance that binds to H+. |
| Strong Acid | Completely dissociates in solution, releasing all of its hydrogen ions and thus lowering solution pH level. |
| Weak Acid | Does not release all of it's hydrogen ions in a solution. |
| Strong Base | Strong tendency to bind H+ and having a lesser effect on solution pH. |
| Weak Base | Bind less of H+, having lesser effect on solution pH. |
| PCO2 Levels | 40-45 mm Hg |
| Bicarbonate Levels | 22-30 mmol/L |
| pH Levels | 7.35-7.45 |
| In Order to Maintain Homeostasis.. | Utilize both chemical and physiological buffering systems. |
| Formula for Acid Base Balance | H₂O+CO₂⇌H₂CO₃⇌H⁺+HCO₃- |
| Acidosis | pH falls below 7.35. |
| Alkalosis | pH rise over 7.45. |
| Respiratory Acidosis | Hypoventilation, decrease in blood that include: airway obstruction, depression of the respiratory center in the brain stem, lung disease, and drug overdose. Secretion of H+ into urine causes an increase in plasma pH. |
