Study Notes

Pulmonary and Airway Management

  • Pulmonary artery carries venous blood from the heart to the lungs.
  • Endotracheal intubation (ETT) is preferred for patients with aspiration risks due to emesis; LMA or combitube are alternatives.
  • A cricothyrotomy is performed in cases of airway obstruction.
  • Nasopharyngeal airways help when the tongue obstructs the airway; can be placed in awake patients.
  • Oropharyngeal airways position the tongue anteriorly but are not well-tolerated by awake patients.

Emergency Medications

  • Atropine is administered for symptomatic bradycardia.
  • Adenosine is used in supraventricular tachycardia (SVT) emergencies.
  • Amiodarone is indicated for ventricular tachycardia (V.tach).
  • Epinephrine is given for ventricular fibrillation (V.fib) and asystole; maximum dose is 0.04mg for cardiovascular disease patients and 0.2mg for healthy patients.
  • Lidocaine treats premature ventricular contractions (PVCs).
  • Dantrolene and IV cold saline are used in malignant hyperthermia cases.
  • Benzodiazepines like Versed, Valium, or Propofol can be used for severe hyperventilation.

Cardiovascular and Hematology

  • Hypertension is defined as a blood pressure of 140/90 or greater, associated with headaches and dizziness.
  • Hematocrit levels: Men (42-52%), Women (37-48%); below 35% indicates anemia.
  • Normal hemoglobin levels: Males (13-18 mg/dL), Females (14-16 mg/dL).
  • Ischemia refers to reduced blood flow and lack of oxygen to heart cells.

Heart Failure

  • Right-sided heart failure leads to peripheral edema and ascites from increased pressure in blood vessels.
  • Left-sided heart failure causes fluid leakage into lungs, presenting as shortness of breath.

Nervous System and Vital Nerves

  • The olfactory nerve (1st cranial) controls smell, while the optic nerve (2nd cranial) controls sight.
  • The vagus nerve (10th cranial) serves various body parts, including thoracic and abdominal viscera.
  • The purkinje fiber system facilitates rapid contraction impulses in heart muscles.

Renal and Endocrine Functions

  • Kidneys maintain body fluid volume and composition, filtering waste and toxins.
  • Islets of Langerhans in the pancreas regulate insulin and glucagon, stabilizing blood sugar levels.
  • The adrenal glands secrete critical hormones like epinephrine and corticosteroids.

Respiratory Conditions

  • Bronchospasm involves contraction of bronchial smooth muscles, restricting airflow.
  • Patients predisposed to bronchospasm include those with asthma, COPD, or bronchitis.

Cardiac Dysrhythmias and Emergencies

  • Pulseless electrical activity (PEA) shows a normal heart trace but lacks a pulse.
  • Asystole presents as a "flat line" on the monitor and requires immediate CPR.
  • T’s and H’s are mnemonic aids for reversible causes of pulseless electrical activity.

Antibiotic Prophylaxis

  • Needed for patients with history of infective endocarditis, prosthetic valves, or congenital heart defects.
  • High-risk patients include those with prior joint infections or immunocompromised conditions.

Common Review of Systems

  • Neurological: Headaches, visual disturbances, weakness.
  • Gastrointestinal: Nausea, vomiting, loss of appetite.
  • Cardiovascular: Dizziness, shortness of breath, chest pain.
  • Musculoskeletal: Muscle cramps, weakness, atrophy.
  • Genitourinary: Painful urination, blood in urine.

Diseases and Conditions

  • Cushing's disease involves hypersecretion of glucocorticoids; Addison's represents life-threatening hypo-secretion.
  • Cirrhosis is liver fibrosis that complicates medication metabolism, posing risks for prolonged drug effects and bleeding.

Heart Valve and Rhythm Issues

  • Mitral valve prolapse (MVP) leads to regurgitation into the left atrium.
  • Cardiovascular assessments indicate class disturbances, ranging from no disturbances (Class I) to severe life-threatening conditions (Class V).
