  • Peripheral-Vascular System
    Branching network of vessels that transports oxygenated blood to all body organs and tissues and then returns it to the heart for reoxygenation in the lungs
  • Peripheral-Vascular System
    • Delivers blood to all areas of the body
    • Blood flows through arteries, veins, and capillaries
    • Measured by pulse and pressure
    • Adequate perfusion to vital organs and extremities is essential to life
  • Disruption in the Peripheral-Vascular System
    Can cause significant pain, loss of limb, or even death
  • Lymphatic System

    • Complements the function of the vascular system
    • Collects and drains excess tissue fluid that accumulates from the cardiovascular system and returns this fluid to the heart
  • Lymphatic System

    • Helps the heart and peripheral vasculature maintain adequate circulation
    • Lymphatic dysfunction may result in reduced range of motion, permanent disfigurement, and susceptibility to infection
    • Responsible for movement of lymph fluid, development and maintenance of the immune system, and reabsorption of fat and fat-soluble substances from the small intestine
  • Structures of the Lymphatic System
    • Lymph
    • Lymphatic Capillaries
    • Lymphatic Vessels
    • Lymph Nodes
    • Tonsils
    • Thymus
    • Spleen
    • Peyer's Patches
  • Functions of the Lymphatic System Structures
    • Lymph - Excessive fluid from body tissue that has drained into lymphatic capillaries
    • Lymphatic Capillaries - Collects fluid from interstitial space and surrounding tissue
    • Lymphatic Vessels - Drain lymph back to right lymphatic duct and thoracic duct
    • Lymph Nodes - Filter microorganisms and foreign substances from lymph
    • Tonsils - Destroy microorganisms and foreign substances at beginning of digestive and respiratory tracts
    • Thymus - Forms antibodies in newborn and developing immune system, secretes thymosin to help T-cell differentiation
    • Spleen - Filters blood and produces lymphocytes and monocytes
    • Peyer's Patches - Respond to antigens by producing antibody
  • Lymphatic System

    Depends on the cardiovascular system, contraction of smooth muscles within lymphatic vessels, and skeletal muscle contraction to pump lymph throughout the body
  • Obstruction of lymphatic system flow

    Lymph may diffuse into the vascular system or collateral channels (to provide alternate routes) may develop
  • Infection in the lymphatic system can occur at any age
  • When assessing the peripheral-vascular and lymphatic systems
    • Begin by asking for the person's chief complaint
    • You may need to ask which symptom is the most bothersome
  • Major vascular symptoms to watch for
    • Swelling
    • Limb pain
    • Changes in sensation of an extremity
  • Always ask about fever, fatigue, and lumps when evaluating the lymphatic system
  • The past health history can provide direct links to the patient's present health status
  • The family history identifies any causative factors that may lead to problems with the peripheral-vascular or lymphatic system
  • The cause of lymphomas, lymphosarcoma, and cancer of the lymph glands is unknown
  • A complete review of systems is an essential component of the assessment
  • The psychosocial profile reveals patterns in the patient's life that may affect the health of their peripheral-vascular and lymphatic systems
  • Before examining the peripheral-vascular and lymphatic systems, review the location of pulse sites, and remember that the lymphatic system drains toward the center of the body
  • Keep key history findings, especially the chief complaint, in mind as you assess
  • Tools for examination of the peripheral-vascular and lymphatic systems
    • Stethoscope
    • Sphygmo-manometer
    • Flashlight
    • Ruler
    • Non-stretchable tape measure
  • You may be able to combine the peripheral-vascular and cardiovascular physical assessments
  • Physical assessment of the lymphatic system is usually integrated into the assessment of other body systems
  • A head-to-toe approach is suggested to incorporate the peripheral-vascular and lymphatic systems
  • Be alert for signs of an acute illness or chronic problem when performing a general survey
  • Observe for edema, which is associated with peripheral-vascular or lymphatic disease
  • Abnormal posture, gait, and movements may signal an autoimmune disease
  • Elevated temperature may indicate an infection; changes in blood pressure and pulse may indicate a cardiovascular problem
  • Assessment techniques for upper extremities
    • Inspect color, lesions, edema
    • Test capillary refill
  • Normal variations for upper extremities
    • Skin color uniform
    • Fingernails of equal thickness
    • Positive brisk capillary refill less than 2 to 3 seconds
    • No edema, erythema, red streaks, or skin lesions
  • Abnormal findings for upper extremities
    • Delayed capillary refill time
    • Edema
    • Lymphedema secondary to mastectomy
    • Intermittent pallor and cyanosis of hands and fingers
    • Ischemic changes and gangrene of hands and fingers
    • Streaky redness, tenderness, warmth along course of a vein
  • Assessment techniques for abdomen
    • Inspect arterial pulsations over the abdominal aorta
    • Note abdominal venous pattern and flow
  • Normal variations for abdomen
    • Abdominal contour flat, concave, or round
    • Abdominal veins barely visible. Veins flowing upward above and downward below umbilicus
    • Arterial pulsations at midline over aorta in thin adults
  • Abnormal findings for abdomen
    • Tense, shiny abdominal skin
    • Upward or centrifugal venous flow
    • Visible, large, diffuse pulsations
  • Assessment techniques for lower extremities
    • Inspect color, lesions, edema, hair distribution, and condition of nails
  • Normal variations for lower extremities
    • Leg hair distributed evenly
    • No varicosities or only superficial ones
    • No swelling or edema
    • No lesions or ulcers
  • Abnormal findings for lower extremities
    • Hair loss, thin shiny skin, and thick nails
    • Eczema, stasis dermatitis
    • Prominent leg veins, possibly with ropelike, dilated appearance or purplish spider-like appearance
    • Edema
    • Skin ulcers
  • When evaluating pulses, use the distal pads of your second and third fingers
  • To palpate lymph nodes, use the pads of your second, third, and fourth fingers, and gently palpate for superficial nodes
  • Assessment techniques for head and neck pulses
    • Note rate, rhythm, amplitude, contour, symmetry, thrills
    • Carotid pulse: Gently palpate along sternocleidomastoid muscle
    • Temporal pulse: Gently palpate next to eyes over temporal area
