    Study Notes

    Clinical Reasoning

    • Clinical reasoning is a process that helps therapists collaborate with patients and provide them with meaningful goals, health management strategies based on clinical data, patient preferences, and professional judgement.

    Clinical Skills

    • Clinical skills include history-taking, physical examinations, clinical investigations, diagnostic reasoning, procedural proficiency, effective communication, teamwork, and professionalism.
    • They support the diagnosis and treatment process.

    Physical Examination

    • Physical Examinations are hands-on observational examinations of patients.
    • They involve observing the patient's demeanor, complexion, posture, and level of distress, before taking action.
    • Clinical investigations are used to obtain a more comprehensive understanding of a patient's condition, including medical history, family history, and lifestyle factors.
    • Physical examinations also include testing of various bodily functions.
    • Refine subsequent diagnostic procedures and prevent unnecessary invasive testing.

    Clinical Medicine Diagnostics

    • Clinical medicine diagnostics involves methods and tools used to identify diseases, disorders, and medical conditions in patients.

    Diagnostic Tools

    • Biochemical methods involve analyzing samples taken from patients, such as blood, urine, and tissue. Examples of biochemical tests include blood tests, enzyme tests, urine tests, and mineral content tests.

    • Physical methods involve using instruments to measure physical parameters such as blood pressure, body temperature, and heart rate.

    User-Device System

    • User-Device interaction considers how users perceive information from a device, interpret it, and make decisions.

    Cardiovascular System

    • Cardiovascular system (or circulatory system) transports blood, oxygen, nutrients, and hormones throughout the body.
    • It consists of the heart, blood vessels, and blood.

    Blood

    • Blood is composed of formed elements (cells and cell fragments) suspended in a liquid called plasma.

    • Plasma*

    • More than 90% of plasma is water.

    • Contains dissolved proteins, nutrients, metabolic wastes, and other molecules.

    • Plasma proteins are categorized into three groups: albumins, globulins (overlapping functions), and fibrinogen (important for clotting).

    • When fibrinogen is removed, the remaining fluid is called serum.

    • Blood Cells*

    • Leukocytes (white blood cells) are involved in immune defenses and include:

      • Neutrophils (engulf microbes by phagocytosis)
      • Eosinophils (fight eukaryotic parasites by releasing toxins)
      • Monocytes (circulate in blood and become macrophages)
      • Macrophages (engulf viruses and bacteria)
      • Basophils (secrete heparin to prevent clotting and aid in flushing infected sites)
      • Lymphocytes (T cells and B cells combat specific pathogens by directly killing them or producing antibodies)

    • Platelets are cell fragments involved in maintaining homeostasis and blood clotting.

    • Erythrocytes (red blood cells) are produced by bone marrow and carry oxygen and carbon dioxide.

      • Contain hemoglobin, a protein that binds oxygen and carbon dioxide reversibly.

    • Hematocrit*

    • Hematocrit is the percentage of blood volume occupied by erythrocytes.

    • It is measured by centrifuging blood and observing the packed erythrocytes.

    Heart

    • The heart is the central pump of the circulatory system:
      • Chambers: 2 atria (upper) and 2 ventricles (lower) work together to ensure efficient blood circulation.
      • Valves:
        • Semilunar valves prevent backflow from arteries to ventricles during ventricular diastole (relaxation):
          • Aortic valve: between the left ventricle and aorta
          • Pulmonary valve: between the right ventricle and pulmonary artery
        • Atrioventricular (AV) valves prevent backflow from ventricles to atria during ventricular systole (contraction):
          • Tricuspid valve: between the right atrium and right ventricle
          • Bicuspid (mitral) valve: between the left atrium and left ventricle. Both are anchored by chordae tendinae.
        • Heart Walls:
          • Endocardium: Innermost layer that lines chambers and valves, continuous with blood vessel linings.
          • Myocardium: Middle, thickest layer composed of cardiac muscle tissue. Responsible for heart contraction.

    Sequence of Cardiac Excitation

    • SA node (sinoatrial node) is the natural pacemaker of the heart.
      • Its depolarization initiates the action potential that spreads to other cardiac muscle cells.
    • AV node (atrioventricular node) links atrial depolarization to ventricular depolarization.
    • Bundle of His and Purkinje fibers conduct action potentials rapidly from the AV node to the ventricular myocytes.
