    Study Notes

    Heart Anatomy and Blood Flow

    • The tricuspid valve prevents backflow of blood from the right ventricle to the right atrium.
    • The right atrium receives deoxygenated blood from the inferior and superior vena cavae.
    • Oxygen-rich blood is supplied to the heart by coronary arteries, which branch off the aorta.

    Cardiac Function and Electrical Impulses

    • The sinoatrial (SA) node initiates the electrical impulse that triggers heart contractions.
    • Capillaries are microscopic blood vessels connecting arterioles to venules for nutrient and gas exchange.
    • The force exerted within blood vessels during heart contraction is termed systolic blood pressure.

    Medical Response and Conditions

    • Perfusion is the process of delivering oxygen and nutrients to cells while removing waste products.
    • In cases of chest discomfort, initial assessment should consider potential cardiac problems.
    • Nitroglycerin is commonly prescribed for anginal chest pain, but blood pressure must be monitored.

    Dosage and Administration Guidelines

    • If no relief occurs after one dose of nitroglycerin, a second dose may be given every 3 to 5 minutes, up to a maximum of three doses.
    • Avoid administering nitroglycerin if the systolic blood pressure is below 100 mmHg.

    Cardiac Events and Emergencies

    • Acute myocardial infarction refers to the death of heart muscle due to inadequate oxygenated blood.
    • The heart may show ventricular fibrillation during cardiac arrest, characterized by uncoordinated twitching.

    Rhythm and Electrical Activity of the Heart

    • Asystole denotes a complete lack of electrical activity and pumping action in the heart.
    • Pulseless electrical activity occurs when the heart has electrical activity but fails to pump effectively.

    ECG and Cardiac Assessment

    • The P wave in a 12-lead ECG represents atrial depolarization.
    • In acute coronary syndrome, "acute" references sudden onset of symptoms rather than duration.
    • Signs of angina pectoris include anxiety, diaphoresis, and dyspnea; diarrhea is not associated.
    • Aortic dissection presents with sharp or tearing pain and may involve syncope (fainting) as a key symptom.

    Summary of Key Points

    • Cardiac arrest in children is mostly due to hypoxia.
    • Proper identification of symptoms and contraindications is crucial in emergency care, like the recent use of Viagra before giving nitroglycerin.

    Abdominal Emergencies Overview

    • Abdominal emergencies often involve serious conditions beyond common issues like gas.
    • Solid organs (e.g., liver, spleen) typically bleed, while hollow organs (e.g., intestines, bladder) release contents that can lead to infection.

    Causes of Abdominal Pain

    • “-itis” Conditions:
      • Peritonitis: Inflammation of the abdominal wall.
      • Appendicitis: Starts around the bellybutton and radiates to the lower right abdomen; characterized by rebound tenderness.
      • Cholecystitis: Inflammation of the gallbladder; may present with referred pain to the shoulder.
      • Pancreatitis: Inflammation of the pancreas.
      • Gastroenteritis: Inflammation of the gastrointestinal tract.
      • Hepatitis: Inflammation of the liver.

    Cholecystitis Risk Factors

    • Known as the "7 F's":
      • Flatulant
      • Fat
      • Female
      • Age 40 and older
      • Fertile (related to pregnancy)
      • Fair-skinned
      • Freckled

    GI Bleeding

    • Indicates bleeding within the gastrointestinal tract; sometimes has a foul odor.
    • Type of blood observed can include bright red, dark red, or coffee ground-like, indicating different sources of bleeding (e.g., mouth or rectum).

    Esophageal Varices

    • Caused by erosion of the esophageal tract, often linked to alcoholism.
    • Can lead to severe bleeding and complications affecting airway and breathing.

    Abdominal Aortic Aneurysm

    • Similar to thoracic aneurysms but located in the abdomen.
    • May exhibit identical signs and symptoms; possibly detectable as a pulsating mass in thinner individuals.

    Primary Survey

    • General Impression: Assess patient positioning and pain levels, as well as consciousness and chief complaint.
    • Patients usually indicate exact pain locations prior to further assessment (OPQRST).

    Airway and Breathing Assessment

    • A patient who can speak indicates a patent airway.
    • Shallow breathing may occur due to pain.
    • Check for presence of radial pulse and skin condition for further evaluation.

    SAMPLE History and OPQRST

    • Conducting a thorough history using SAMPLE (Signs/Symptoms, Allergies, Medications, Past medical history, Last oral intake, Events leading up to present illness) can help refine diagnosis.
    • Utilizing OPQRST (Onset, Provocation, Quality, Radiation, Severity, Time) aids in understanding the nature and urgency of the abdominal pain.

    Vital Signs and Secondary Assessment

    • Pain can stimulate the sympathetic nervous system, possibly resulting in rapid breathing and pulse, along with poor skin condition.
    • Differential diagnosis is crucial in determining the underlying cause of abdominal emergencies.
