Peripheral Vascular Exam Flashcards
Equipment for peripheral vascular exam
Stethoscope (bruits)
2 rulers and pencil to assess JVP (15 cm long at least)
Penlight (JVD)
Pape measure (calf circumference for JVT)
External clues to circulatory status
Hair pattern on extremities Skin color (cyanosis, rubor, pallor, mottling) Capillary refill time Temperature of skin Pulse strength and regularity Dependent edema
Sequence of blood flow through the systemic circulatory system
See pictures
Pulmonary circulation: Deoxy blood enters SVC & IVC-RA-RV-PA-Lungs
Systemic circulation: oxygenated blood enters heart from PV-LA-LV-Aorta-System (Head and Body)!
Characteristics of arterial pulse and pressure and describe the steps in examination
Arterial pulse: ventricular systole (pressure wave) through arterial system - examining of pulse = carotid
Arterial Pressure: force restarted by blood against wall of artery - from blood exiting left ventricle during contraction
Checking for: stroke volume, ability aorta/larger arteries to distend, obstructed blood flow, peripheral artery resistance, viscosity of blood
Jugular Venous Distention
dissension of external jugular veins, suggests poor right heart function (in athletes may be due to musculature)
JVD exam and interpretation
Tangential light, look at level above clavicle (3-4cm at 45 degree angle could be indication of vascular disease)
Jugular Venous Pressure
A means of estimating right atrial pressure. Venous pressure will rise when right heart fails and is unable to successfully empty
Hepatojugular reflux
dissension of neck veins precipitating the maneuver of firm pressure over the liver. Tricuspid regurgitation, heart failure (non valvular), constrictive pericarditis, cardia tamponade, and IVC obstruction.
Carotid pulse
Location: Just below jaw angle
Brachial pulse
Location: Medial antecubital fossa of elbow
Radial pulse
Location: thumb side of wrist
Ulnar pulse
Location: pinky side of wrist
Abdominal aorta
Location: left lateral and superior to umbilicus
Auscultate before palpating, use both hands measure width (2.5cm)
Femoral
Location: Groin crease
Popliteal
Location: directly behind knee (flexed)
Dorsalis pedis
Location: top of food, btw metatarsals 1 and 2
Posterior tibialis
Location: posterior to medial malleolus of ankle
Amplitude of pulse, rating scale
0= no palpable pulse 1+ = diminished 2+ = normal/expected 3+ = full/increased 4+ = bounding
Pulsus alternans
Pulse has constant rate and rhythm but amplitude (force) alternates between a smaller amplitude and larger amplitude
*Can be due to left ventricular dysfunction
Pulsus bigeminus
Normal pulse beat followed by a premature beat (due to premature ventricular contraction) and a pause.
*Can be due to heart disease, digitalis toxicity, or a temporary benign finding
Pulsus bisferiens
Pulse has two peaks during systole: the first is the ‘normal’ pulse that occurs during ventricular contraction, but the second is an early diastole due to a back flow of blood; best noticed with palpation of carotid artery.
*Can be due to severe aortic regurgitation or aortic stenosis coupled with aortic insufficiency
Pulsus paradoxous
Atypical decrease in systolic arterial BP (>10mmHg) and amplitude during inspiration. Normally there is a slight decrease in BP with inspiration, but less than 10 = abnormal. Detected by taking BP (difficult to detect with palpation)
*Can be due to emphysema, asthma, premature heart contraction, tracheobronchal obstruction, pericardial effusion
Pulsus deficit
Difference between the rates in pulse when auscultating the heart’s apex vs. palpating a peripheral artery
*Occurs when ventricular contraction doesn’t eject a sufficient amount of blood to produce a pulse wave in the arteries. Often associated with premature beats, pulses bigeminus, and atrial fib.
Locations to assess for bruits
turbulent blood flow though the corresponding artery.
May indicate murmur, stenosis, aneurysm, etc.
Locations: Carotid, subclavian, abdominal aorta, renal, iliac, and femoral arteries.
