    Study Notes

    Cardiovascular and Peripheral Vascular Lecture

    • Learning Outcomes: Students will be able to conduct and assess the cardiovascular and peripheral vascular systems (including lymphatics). This includes applying knowledge of anatomy and physiology related to examination of the heart and peripheral vascular systems, linking this knowledge to the concept of perfusion, identifying general survey findings and health history questions, explaining correct assessment techniques, interpreting expected heart sounds, relating assessment techniques to a head-to-toe approach, differentiating expected and unexpected findings, and documenting findings.

    November 6, 2024 Class Agenda

    • Video: Heart Anatomy Review
    • Cardiac Physiology Review: Electrical Involvement and PQRST, Cardiac Cycle, Perfusion
    • General Survey: Health History, Physical Assessment
    • Physical Assessment: Peripheral Vascular and Lymphatics Assessment

    Anatomy Review

    • Heart Position: The heart sits mostly to the left of the body, measured from the 2nd to 5th intercostal space. The base of the heart is broad and located at the top; the apex is at the bottom, in the 5th intercostal space, (the point of apical impulse).

    Head and Neck Vasculature

    • Displays anatomical structures of arteries and veins in the head and neck region.

    Physiology Review

    • Provides a diagram of the heart and its function. Shows blood flow through the heart and to the lungs and body.

    Perfusion

    • The process of delivering blood from capillaries to tissues.
    • Cardiac output is a function of stroke volume and heart rate.

    Electrical Conduction of the Heart

    • The SA Node is the natural pacemaker of the heart.
    • The AV Node transmits impulses from the SA node to the HIS and Purkinje fibers, coordinating the heart cycle.

    ECG (Electrocardiogram)

    • ECG waves represent the electrical activity of the heart.
    • P wave: atrial depolarization
    • PR interval: SA-BB conduction
    • QRS complex: ventricular depolarization
    • T wave: ventricular repolarization

    General Survey and Vitals

    • Includes temperature, blood pressure (and MAP), pulse, presence of deficits, and daily weights (taken first thing in the morning after voiding).
    • Taking accurate vitals provides a baseline for assessment.

    Expected and Unexpected Cardiac Findings during General Survey

    • Discussion of these findings.

    Peripheral Vascular System and Lymphatics

    • Review, assessment, and risk factors. This segment examines peripheral vascular components, including arteries, veins, and lymphatics.
    • The lymphatic system: Lymphedema, lymph nodes, Chylothorax

    Assessing the Periphery

    • Assessing peripheral vascular system: (including fascial compartments), pulses, edema, compartment syndrome, and deep venous thrombosis.

    Anatomy and Physiology Review; PVS and Lymphatics

    • Detailed review of the peripheral vascular system and lymphatic system.

    A+P Peripheral Vascular

    • Arteries: Thick walled, elastic with high pressure; a major artery is the aorta
    • Veins: Thinner walled, less elastic with low pressure; have valves preventing backflow, and an example is the superior vena cava.
    • Capillaries: Exchange of gases and nutrients, metabolites take place between tissues and blood.

    A+P Lymphatics

    • The lymphatic system maintains fluid balance and immune function.
    • Lymph drains into Thoracic and Right Lymphatic ducts, subclavian veins, and superior vena cava, which is located at the right atrium of the heart.

    Fascial Compartment

    • Fascia are connective tissues surrounding vessels, nerves, and muscles that form compartments. Limited stretch in fascia can cause problems.

    Deep Vein Thrombosis (DVT)

    • Includes pain, edema, warmth, weak pulses, and delayed capillary refill.
    • A risk for Pulmonary Embolism (PE)

    Health History Analysis of S/S for Periphery

    • Collection of information about pain, numbness/tingling, cramping, changes in skin color, edema, and function.
    • Includes personal history information (medications, family history of stroke, and clots).

    PVS and Lymphatics - Inspect

    • Inspect all extremities, comparing color, size, quality of skin, hair, and nails.

    Lymphedema

    • A condition involving swelling in the extremities caused by lymphatic fluid buildup.

    Edema

    • Detailed assessment of pitting and non-pitting edema, which is classified using a grading scale (0 to 4+).

    Palpation for Lymphatics

    • Methods for palpating lymph nodes in various parts of the body (including supraclavicular, cervical, subclavian, axillary, and inguinal).

    Palpation for PVS

    • Assessing texture, temperature, turgor, capillary refill, edema, and pulses for blood vessel function.

    Pulse

    • Locating and assessing various pulse sites, including temporal, carotid, brachial, apical, radial, popliteal, and pedal pulse rates

    Assessment of Pulses

    • Pulse assessment scale.

    Doppler

    • Use of a Doppler when palpation is not effective in determining blood flow

    Compartment Syndrome

    • Bleeding or swelling after injury can cause compartment syndrome, leading to pain and paresthesia (numbness or tingling).

    Limb Ischemia (6 Ps of Limb Ischemia)

    • Rest pain (worse distally, relieved with dependency), pallor (skin color comparison to contralateral side), pulselessness (doppler use), polar sensation (cold compared to contralateral side), paresthesia (burning/tingling), and paralysis (sign of more advanced complications).

    Infiltration and Extravasation

    • Infiltration and extravasation are additional forms of compartment syndrome in which IV fluids or vesicants leak into surrounding compartments.

    Recall Red Flag Assessment Findings

    • Information relating to red flags and how to connect an interdisciplinary team, if necessary, with regards to assessment findings..
