Allen test
Determining the patency of radial and ulnar arteries by compressing one artery site and observing return of skin color as evidence of patency of the other artery
Aneurysm
Defect or sac formed by dilation in artery wall due to atherosclerosis, trauma, or congenital defect
Arrythmia
Variation from the heart’s normal rhythm
Arteriosclerosis
Thickening and loss of elasticity of the arterial walls
Atherosclerosis
Plaques of fatty deposits formed in the inner layer (intima) of the arteries
Bradycardia
Slow heart rate, <50 beats per minute in the adult
Bruit
Blowing, swooshing sound heard through a stethoscope when an artery is partially occluded
Cyanosis
Dusky blue mottling of the skin and mucous membranes due to excessive amount of reduced hemoglobin in the blood
Diastole
The heart’s filling phase
Homans’ sign
Calf pain that occurs when the foot is sharply dorsiflexed; may occur with deep vein thrombosis, phlebitis, Achilles tendinitis, or muscle injury
Ischemia
Deficiency of arterial blood to a body part due to constriction or obstruction of a blood vessel
Lymphedema
Swelling of extremity due to obstructed lymph channel, nonpitting
Lymph nodes
Small oval clumps of lymphatic tissue located at grouped intervals along lymphatic vessels
Pitting edema
Indentation left after examiner depresses the skin over swollen edematous tissue
Profile sign
Viewing the finger from the side to detect early clubbing
Pulse
Pressure wave created by each heartbeat, palpable at body sites where the artery lies close to the skin and over a bone
Pulsus alternans
Regular rhythm, but force of pulse varies with alternating beats of large and small amplitude
Pulsus bigeminus
Irregular rhythm; every other beat is premature, premature beats have weakened amplitude
Pulsus paradoxus
Beats have weaker amplitude with respiratory inspiration, stronger with expiration
Systole
The heart’s pumping phase
Tachycardia
Rapid heart rate, >90 beats per minute in the adult
Thrombophlebitis
Inflammation of the vein associated with thrombus formation
Ulcer
Open skin lesion extending into dermis with sloughing of necrotic inflammatory tissue
Varicose vein
Dilated tortuous veins with incompetent valves
