1

Allen test

Test that determines the patency of the radial and ulnar arteries by compressing one artery site and observing return of skin color as evidence of patency of the other artery.

2

Aneurysm

Defect or sac formed by dilation in artery wall due to atherosclerosis, trauma, or congenital defect

3

Arrhythmias

Variation from the heart's regular rhythm

4

Arteriosclerosis

Thickening and loss of elasticity of the arterial walls

5

Atherosclerosis

Plaques of fatty deposits formed in the inner layer (intima) of the arteries

6

Bradycardia

Slow heart rate, less than 50 beats per minute in the adult

7

Bruit

Blowing, swooshing sound heard through a stethoscope when an artery is partially occluded

8

Cyanosis

Dusky blue mottling of the skin and mucous membranes due to excessive amount of reduced hemoglobin in the blood

9

Diastole

The heart's filling phase

10

Ischemia

Deficiency of arterial blood to a body party due to constriction or obstruction of a blood vessel

11

Lymph nodes

Small oval clumps of lymphatic tissue located at grouped intervals along lymphatic vessels

12

Lymphedema

Swelling of extremity due to obstructed lymph channel, nonpitting

13

Pitting edema

Indentation left after examiner depresses the skin over swollen edematous tissue

14

Profile sign

Viewing the finger from the side to detect early clubbing

15

Pulse

Pressure wave created by each heartbeat, palpable at body sites where the artery lies close to the skin and over a bone

16

Pulsus alternans

Regular rhythm, but force of pulse varies with alternating beats of large and small amplitude

17

Pulsus paradoxus

Beats have weaker amplitude with respiratory inspiration, stronger with expiration

18

Systole

The heart's pumping phase

19

Tachycardia

Rapid heart rate, more than 95 beats per minute in the adult

20

Thrombophlebitis

Inflammation of the vein associated with thrombus formation

21

Ulcer

Open skin lesion extending into dermis, with sloughing of necrotic inflammatory tissue
