ICU

• Shock


  Inadequate perfusion to the tissues due to insufficient oxygen and nutrients, leading to tissue and organ failure
• Types of shock


  • Hypovolemic
  • Cardiogenic
  • Obstructive
  • Distributive
• Hypovolemic shock


  Caused by decreased blood volume, leading to reduced preload, stroke volume, cardiac output, and perfusion pressure
• Cardiogenic shock


  Caused by reduced cardiac output due to myocardial dysfunction, arrhythmias, or valvular issues
• Obstructive shock


  Caused by obstruction to blood flow, leading to reduced cardiac output
• Distributive shock


  Caused by reduced systemic vascular resistance, leading to decreased blood pressure
