Cardiovascular Disorders & Heart Failure

Hemodynamic pathophysiology of left vs right-sided heart failure, cardiogenic shock cues, BNP biomarkers, and preload/afterload reduction strategies.

High-Yield Clinical Takeaways:

  • •Left-sided HF manifests as pulmonary congestion (crackles, dyspnea, orthopnea, paroxysmal nocturnal dyspnea).
  • •Right-sided HF manifests as systemic venous congestion (jugular venous distension, dependent peripheral edema, hepatomegaly, ascites).

Respiratory Compromise & Acute ARDS

Arterial blood gas (ABG) interpretation, acute respiratory distress syndrome (ARDS) refractory hypoxemia, and mechanical ventilation safety rules.

High-Yield Clinical Takeaways:

  • •Refractory hypoxemia (PaO2 remains low despite 100% FiO2) is the hallmark indicator of ARDS.
  • •Prone positioning significantly improves ventilation-perfusion matching by recruiting dorsal lung regions.

Endocrine Emergencies: DKA vs. HHS

Comprehensive comparison of Diabetic Ketoacidosis (DKA) and Hyperosmolar Hyperglycemic State (HHS), potassium replacement protocols, and fluid resuscitation priorities.

High-Yield Clinical Takeaways:

  • •DKA (Type 1 DM): Rapid onset, glucose 250–500 mg/dL, positive serum ketones, metabolic acidosis (pH < 7.30), Kussmaul respirations, fruity breath.
  • •HHS (Type 2 DM): Insidious onset, severe hyperglycemia (glucose > 600 mg/dL), negative/trace ketones, severe dehydration and hyperosmolality (> 320 mOsm/kg).
