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
