    Study Notes

    Medical Terminology and Concepts

    • CC: Stands for Chief Complaint, indicating the primary reason a patient seeks medical attention.
    • Segment: Refers to the line between two waveforms in an EKG strip.
    • P Wave: Represents arterial depolarization in an EKG.
    • 6 Second Rhythm Strip: Contains 30 one millimeter boxes, useful for rhythm interpretation.

    EKG and Cardiac Function

    • SA Node: Only represents the P wave on the EKG, indicating the heart's natural pacemaker.
    • RR Interval: Provides readings of ventricular pulse, crucial for assessing heart rate.

    Hemolysis and Hemostasis

    • Primary Stage of Hemolysis: Comprises the vascular phase and platelet phase.
    • Stages of Hemostasis: Include Vascular, Platelet Phase, Coagulation Phase, and Fibrinolysis, each critical in stopping bleeding.

    Blood Components and Functions

    • Blood Vessel Types: Aorta, Arteries, Arterioles, Capillaries, Venules, Veins, Superior and Inferior Vena Cavae.
    • Blood Volume: Average adult blood volume is approximately 5-6 liters.
    • Water Content in Blood: Constitutes about 92% of total blood volume.

    Blood Composition

    • Plasma Percentage: Makes up 55% of blood.
    • Formed Elements Percentage: Accounts for 45% of blood, primarily red blood cells (RBCs).
    • RBCs: Comprise 99% of formed elements and are responsible for oxygen transport via hemoglobin.

    Blood Cell Characteristics

    • Blood Cell Origins: All blood cells originate from bone marrow.
    • RBC Count: Typically ranges from 4.2 to 6.2 million per microliter of blood.
    • WBC Distribution: Lymphocytes, the second most numerous white blood cells, make up 20-40% of total leukocytes.

    White Blood Cell Functionality

    • Monocytes: Increase in numbers during intracellular infections and tuberculosis, comprising 3-8% of total WBCs.
    • Neutrophils: First responders in bacterial infections, critical for immune defense.
    • Basophils: Carry histamine, involved in inflammatory responses.

    Phlebotomy and Lab Testing

    • Preferred Venipuncture Site: Antecubital fossa is the most common site for drawing blood.
    • APTT Test: Evaluates intrinsic pathway and monitors heparin therapy.
    • PT Test: Assesses extrinsic pathway and is used to monitor warfarin therapy.

    Blood Vessel Anatomy

    • Tunica Adventitia: Outer connective tissue layer of blood vessels.
    • Tunica Intima: Inner endothelial tissue of blood vessels.
    • Tunica Media: Inner smooth layer of blood vessels.

    Blood Safety and Preparation

    • Antiseptics in Phlebotomy: 70% isopropyl alcohol pads are most common; provolone-iodine for blood cultures, and chlorhexidine gluconate for patients allergic to iodine.
    • Venipuncture Needle Length: Commonly 1 inch, can go up to 1.5 inches for larger veins.
    • Average Needle Gauge for Draws: Typically ranges from 21 to 22 gauge.

    Hemostasis Process

    • Vascular Phase: Initiates injury response by causing blood vessels to constrict.
    • Fibrinolysis: Refers to the breakdown and removal of clots, ensuring proper blood flow post-hemostasis.
