Pulse Grading
A
- Grading
0 = Absent

exercise, anxiety)
22

Characteristics of Pulses
A
Rate
Rhythm
Tortuosity

23
Q
Palpations and Auscultation of the Head & Neck
A
- Palpation: (Bilateral)
- Temporal Pulse (Pain = ? Temporal arteritis)
- Carotid Pulse (Auscultate for bruit first)
- Auscultation: (using bell bilateral) - Temporal Artery for Bruits (Temporal Arteritis)

mobility, & tenderness)
25
Auscultation of the Upper Extremity
1. Measure BP using Brachial Artery bilaterally normal
is 120/80 per JNC7 criteria
a. Change in BP > 20 mmHg Systolic & 10 mmHg
diastolic from arm to arm is abnormal
b. Orthostatic Hypotension
c. Pulsus Paradoxus
26
Pulsus Paradoxus
is a decrease in BP > 10 mmHg
during inspiration and may indicate several
conditions including Cardiac Tamponade, Pericarditis,
COPD, Chronic Sleep Apnea, & Croup
27
Orthostatic Hypotension
is a decrease in systolic
BP > 10 mmHg & increase in heart rate > 10 bpm
with change of position from lying flat to sitting &
then to standing indicates hypovolemia
28
Allen's Test
for patency of radial & ulnar arteries
prior to A-line insertion or use of Radial A. in CABG
or for Cardiac Cath canulation
29
Adson's Test and Wright's Maneuver
Test for Thoracic
Outlet Syndrome with complaints of pain or
numbness in arms from compression of
Subclavian A. between clavicle & 1st rib
30
Palpation of Lower Extremity
1. Skin turgor, temperature, & texture
2. Muscle Tone
3. Proprioception of toes (early sign of acute arterial
ischemia)
4. Capillary Refill (< 2 sec. is normal)
5. Femoral Pulse
6. Inguinal Lymph Nodes
7. Popliteal Pulse
8. Posterior Tibialis Pulse
9. Dorsalis Pedis Pulse
31
Auscultation of Lower Extremity
1. Femoral for bruits with bell
2. Use of doppler will help determine flow in others
a. Biphasic = normal
b. Monophasic or Absent = abnormal
32
Ankle Brachial Index
measures systolic BP in
Brachial A. and compares with Posterior Tibial A. &
Dorsalis Pedis A. using a doppler
Index
1 – 1.2 normal
< 0.9 mild to moderate PAD
< 0.4 severe PAD
> 1.3 non-compressible (DM & Chronic RF)
33
Other Tests that can be used for arterial Peripheral Vascular Disease
- PVR & segmental limb pressures
- Ultrasound
- MRA– no radiation
- CT Angiography
- Conventional Angiography
34
Palpation of abdominal aorta
1. Aorta – just above umbilicus with patient supine,
try to find the edges normal width approx. 3 cm if
greater may indicate AAA
35
3 Systems of the venous system
1. Superficial
2. Deep
3. Perforating – connects superficial to deep
All 3 systems have one way bicuspid valves that permit flow from superficial to deep & distal to proximal
36
3 functions of the venous system
1. Return deoxygenated blood to the heart
2. Storage – contains 70% of total blood volume
3. Thermoregulation
4. Regulation of Cardiac Output
37
Venous System Problems
Valvular Dysfunction – varicosities
Deep Venous Obstruction – DVT/PE
Chronic Venous Insufficiency – chronic DVT & post phlebitic syndrome
Superficial Vein Inflammation or Infection – superficial phlebitis
38
Inspection of the Venous System PE
in supine & standing positions
- Unilateral/Bilateral extremity edema
- Dyspnea
- Presence of Varicosities
- Pain/Discomfort/Cyanosis of extremities
- Skin tension
- Hyperpigmentation of lower leg
- Ulcers
- Pallor with patchy cyanotic or gangrenous areas
- Presence of skin bullae or vesicles
- Prominent & dilated veins on chest wall & neck
along with facial edema = SVC obstruction
39
Palpation of LE
- Tenderness
- Increased skin temp
- Edema – pitting vs non-pitting
- Measure circumference of calf at the same point on
both sides 10 cm distal to tibial tubercle
- Induration
- Pulses of extremities
40
Special Tests of the Venous System
1. Venous Duplex Doppler to r/o DVT
2. D-Dimer controversial use based on PERC criteria
3. Chest Spiral CT to r/o PE
