Pulse and blood pressure measurements taken in different areas of the body help diagnose peripheral arterial disease.

Peripheral Pulses +1

Pulse

Peripheral Pulses Scale

In the legs, doctors will commonly feel for pulses in the femoral (groin), popliteal (back of the knee), posterior tibial (ankle), and dorsalis pedis (foot) areas. Other pulses often checked include the radial (wrist), brachial (forearm), and carotid (neck) areas.

The pulses are graded for record-keeping purposes so that doctors can keep track of how a person's pulse changes over time. Your doctor uses a number system to rate your pulse.

Your doctor will listen to your pulse with a stethoscope for a 'whooshing' sound called a bruit (say 'broo-E'). A bruit might mean there is a blockage in the artery.

Blood pressure

For peripheral arterial disease, blood pressure might be taken at the ankles, toes, legs, and arms.

Blood pressures are typically taken with a blood pressure cuff. But blood pressure can be measured using catheters placed inside the arteries. Because the arteries are punctured, this is known as invasive blood pressure monitoring.

Ankle pressure

In most people, the resting ankle pressure is greater than the pressure at the crook of the arm, known as the brachial blood pressure. The ratio of the ankle pressure to the brachial pressure is called the ankle-brachial index (ABI).

Toe pressure

Toe pressures can be measured with miniature blood pressure cuffs to check for poor blood flow in the toes.

Segmental leg pressures

Arterial pressure can be estimated in the upper thigh, above the knee, and in the upper calf by placing blood pressure cuffs at the appropriate levels. The pressures can be compared between the two legs or at different levels in the same leg.

Arm pressures

Blood pressures can be measured at the elbow (brachial), forearm, or wrist. Large differences between pressures at the various levels suggest arterial blockage. As with toes, finger pressures can be measured.

Peripheral Arterial Disease: Pulse and Blood Pressure Measurement

Part II: Assessment Techniques

Inspection

As you prepare to begin the actual assessment, you already have obtained and recorded the patient history and you arm yourself with pertinent data such as their chief complaint and allergic history.

Also keep in mind to allow a certain amount of time in order to complete a thorough exam. Many nurses do not have large blocks of time for completion of the assessment but you must be as thorough as possible. If this is an admission assessment, you must allow enough time to be complete. If this is an on-going assessment, not as much time will be required.

Begin Exam

Peripheral Pulses

Patient undresses, but allow for privacy.
Have the patient sit upright and inspect the thorax from the front.
Now inspect from the back of the patient.

You will inspect for posture and symmetry of the thorax, color of the skin, gross deformities of the skin or bone structure, the neck, face, eyes, and any abnormal contours. Breathing patters will also be noted. Be especially aware of the presence of cyanosis. Central cyanosis is a condition which will cause the lips, mouth, and conjunctiva to become blue. Peripheral cyanosis will cause blue discoloration mainly on the lips, ear lobes, and nail beds. Peripheral cyanosis might indicate a peripheral problem of vasoconstriction, and would generally be less severe than central cyanosis, which could indicate heart disease and poor oxygenation.

Thorax

Inspect for symmetry of thorax, point of maximum intensity (PMI). PMI is easier to find if the patient will lay on the left side. PMI may also be palpated. Check skin color of thorax.

Eyes

Arcus Senilis is a light gray ring surrounding the iris, common in older patients; in younger patients it might indicate a type of lipid metabolism disorder, which is a precursor to coronary artery disease.

Xanthelasma is yellowish raised plaques on the skin surrounding the eyes. Can also appear on the elbows. This is a possible indication, or sign of hypercholesterolemia, often a precursor to coronary artery disease (atherosclerosis).

Palpation

Palpation, or touching, is the next part of the exam. In the stop above, if we noted any abnormalities, we will now palpate and evaluate them further.

Skin: temperature, texture, moisture, lumps, bumps, tenderness.

Examination of extremities for edema might also indicate a cardiovascular problem. Examine the feet, ankles, sacrum, abdomen, trunk, and face for edema. If you notice puffiness of frank edema, then palpate the area for pitting edema. Most facilities recognize the following scale:

+1 Pitting Edema	=	0 to ¼ inch indentation
+2 Pitting Edema	=	¼ to ½ inch indentation
+3 Pitting Edema	=	½ to 1 inch indentation
+4 Pitting Edema	=	More than 1 inch indentation

Breathing: lay hands the chest at different locations and feel the respiratory patterns, feel the ribs elevate and separate during normal breathing.

Pre-Cordial Areas you can feel the pounding of the heartbeat, normal and abnormal pulsations o the chest wall; PMI, as mentioned above.

Arteries: Assess all pulses

You undoubtedly assessed the apical pulse earlier when you took the patient’s vital signs, if not, now is the time. Assess the following pulses:

Apical heart rate – monitor for a full minute, note rhythm, rate, regularity.
Radial pulse – monitor for a full minute. Note the rhythm, rate, and the regularity. Note any differences from right to left radial, a large difference might indicate arterial blockage or even enlarged ventricles. If pulse is regular but volume diminishes from beat to beat, this might indicate left-sided heart failure and is called pulses alternans. If the volume of the pulse diminishes on inspiration, might indicate constrictive pericardial disease, the condition is called pulsus paradoxus.
Carotid, brachial, femoral, popliteal, posterior tibialis, and dorsalis pedis pulses – when checking these pulses do it the same way as the others mentioned in this section; right then left side. When you check the carotid, press gently and do not rub.

Do not palpate carotid on persons with known carotid disease or bruits; listen with stethoscope instead; and do not palpate both carotid pulses at the same time.

Carotid Artery:

Plateau pulse – slow rise and slow collapse pulse; may be caused by aortic stenosis, slow ejection of blood through a narrowed aortic valve.
Decreases amplitude (grade point pulse) – due to hemorrhagic shock, pulse is weak due to decreased blood volume.

Bounding Pulse - (Grade IV) can be due to hypertension, thyrotoxicosis, others; associated with high pulse pressure, the upstroke and downstroke of the pulse waves are very sharp.

It is common to use +1, +2, etc. when recording pulses:

Peripheral Pulses Palpable

0 = absent
+1 = diminished or decreased
+2 = normal pulses
+3 = full pulse or slight increase in pulse volume
+4 = bounding pulse or increased volume

Peripheral Pulses 3+

Veins – neck, arms, legs, etc.
