| blood pressure (BP) | pressure exerted by blood against blood vessel walls. Systolic pressure (120)/diastolic pressure (80) |
| cardiopulmonary resuscitation (CPR) | emergency procedure consisting of artificial ventilation and external cardiac massage |
| diastole | phase in cardiac cycle in which ventricles relax between contractions (lower number of blood pressure reading) |
| extracorporeal | occurring outside the body |
| extravasation | escape of blood from blood vessel into tissue |
| heart murmur | short-duration humming sound of cardiac or vascular origin |
| hypertension | blood pressure that is above normal (>140/90) |
| hypotension | blood pressure that is below normal (<90/60) |
| lumen | space within tubular part or organ |
| occlude | to close tightly; to block |
| percussion | tapping of body surface with fingers to determine density of part beneath |
| systole | phase in cardiac cycle in which ventricles contract (upper number of blood pressure reading) |
| vasoconstrictor | agent or nerve that restricts blood vessels |

| venipuncture | puncture of vein to remove blood, instill medication, or start IV infusion |
| anticoagulant | agent that slows clotting process |
