Study Notes

Types of Shock

  • Hypovolemic shock occurs when there is an inadequate circulating blood volume due to dehydration or significant hemorrhage.

Prevalence of Shock

  • Hypovolemic shock is the most common type of shock encountered in patients.

Complications of Untreated Shock

  • Untreated shock can lead to organ failure, and eventually, death if left untreated for a prolonged period of time.

Diagnosing Shock

  • Diagnosis of shock can be made through a combination of physical examination, medical history, and laboratory tests, including:
    • Complete Blood Count (CBC)
    • Electrolyte panel
    • Arterial Blood Gas (ABG)
    • Serum lactate measurement
    • Urinalysis

Diagnostic Imaging

  • A chest x-ray can reveal:
    • Pulmonary edema or congestion in a patient with shock
    • Cardiomegaly or an enlarged heart
