| pH | hydrogen ION |
| Respiratory Acidosis | caused by the retention of CO2 |
| Metabolic Acidosis | results from the production of metabolic acids such as lactic acid, which consume bicarbonate ion |
| Respiratory Alkalosis | results from increased respiration and excessive elimination of CO2. May occur with anxiety |
| Metabolic Alkalosis | Occurring less frequently than acidosis.. usually caused by the administration of diurtetics. Also from the overzealous administration of sodium bicarbonate |
| Hypoperfusion | Inadequate perfusion of the body's tissues and cells. Also known as shock |
| Aerobic metabolism | the second stage of metabolism requiring the presence of oxygen in which the breakdown of glucose yields a high amount of energy |
| Anaerobic metabolism | the first stage of metabolism which does not require oxygen |
| Compensated shock | early stage of shock during which the body's compensatory mechanisms are able to maintain normal perfusion |
| Decompensated Shock | Advanced stages of shock when the body's compensatory mechanisms are no longer able to maintain normal perfusion |
| irreversible shock | shock that has progressed so far that no medical intervention can reverse the condition and death is inevitable |
| Cardiogenic shock | shock caused by insufficient cardiac output |
| Hypovolemic shock | shock caused by a loss of intravascular fluid |
