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.
