| Benzodiazepine | Chemical classification of agents used as sedatives. |
| Capnography | Measurement of inspired and expired carbon dioxide concentrations. |
| Capnometry | Measure of expired carbon dioxide. |

| Desaturation | Reduction of oxygen saturation in the blood. |
| Dysrhythmias | Abnormal, disturbed cardiac rhythm. |
| Electrocardiography | A process of recording electrical activity in the heart. |
| Electroencephalogram | A record of electrical activity in the brain. |
| Emergence phase | Begins as anesthetic agents are discontinued and allowed to wear off and ends when patient is transported to PACU. |
| Fasciculation | Small, local, involuntary muscular contraction visible under the skin. |
| Hemoglobinuria | Presence of free hemoglobin in the urine. |
| Hypermetabolic | Increased metabolism. |
| Induction phase | Begins when medications are administered to initiate general anesthesia and concludes when an adequate depth of anesthesia is reached and the patient’s airway is secured. |
| Intrathecally | Pertaining to within the spinal canal. |
| Maintenance phase | Begins as the patient’s airway is established and secured and continues until the surgical procedure has been completed. |
| Precordial | Pertaining to the anterior surface of the body overlying the heart. |
| Pyrexia | A fever, or febrile condition. |
| Repolarization | Restoration of the polarized state at the cell membrane. |
| Tachypnea | Very rapid respirations, greater than 30 per minute. |
| Vagolysis | Blocking the effects of the vagus nerve. |
| Analgesia | Absence of a normal sense of pain. |
| Anesthesiologist | Physician who specializes in anesthesia delivery and the maintenance of the patient's physiologic condition during surgery. |
| Anterograde | From a point forward, as in memory impairment from the time an amnestic agent is administered. |
| Anticholinergic | An agent that blocks parasympathetic nerve impulses; a vagolytic, parasympatholytic agent. |
| Aspiration | Inspiration of foreign material into the airway. |
| Hematocrit | Measure of the volume of red blood cells in whole blood. |
| Hemoglobin | A protein in red blood cells that is responsible for gas exchange; a measure of the amount of that protein. |
| Opioid | An agent containing opium or any of its derivatives. |
| Sedative | An agent used to produce a calm, relaxed state. |
| Epidural | Above or upon the dura. |
| Exsanguination | To render bloodless. |
