How is obstructive shock diagnosed?

Obstructive shock can be diagnosed based on a thorough review of the individual’s medical history and physical examination. A detailed respiratory and cardiovascular examination is necessary in order to distinguish the underlying cause of obstructive shock.

How can you distinguish between obstructive and cardiogenic shock?

Obstructive shock is similar to cardiogenic shock in that the impaired heart function is the primary abnormality. In cardiogenic shock, the contractility is impaired; but in obstructive shock, the heart is prevented from contracting appropriately.

What is an example of obstructive shock?

Examples of obstructive shock include acute pericardial tamponade, tension pneumothorax, pulmonary or systemic hypertension, and congenital or acquired outflow obstructions.

What signs are present as obstructive shock progresses pals?

Signs and Symptons:

  • Airway: may have compromised airway if level of consciousness is decreased.
  • Breathing: increased work of breathing and respiratory rate; respiratory distress.
  • Circulation: tachycardia, cyanosis, chest pain, and hypotension.
  • Disability: decreased level of consciousness.
  • Exposure: cool extremities.

Which causes of shock are considered to be obstructive?

Hypovolemic shock (intravascular volume loss) Obstructive shock (physical obstruction of blood circulation and inadequate blood oxygenation)

Is hypovolemic shock obstructive shock?

Hypovolemic shock relates to the blood and fluids compartment while distributive shock relates to the vascular system; cardiogenic shock arises from primary cardiac dysfunction; and obstructive shock arises from a blockage of the circulation.

What is obstructive shock caused by?

Obstructive shock results from an intrinsic or extrinsic obstruction of circulation. Pulmonary embolism and pericardial tamponade both result in obstructive shock.

What causes obstructive shocks?

It is caused by mechanical obstruction of blood flow to and/or from the heart and causes can include a tension pneumothorax, cardiac tamponade, pulmonary embolus, or cardiac defects resulting in left-sided outflow tract obstruction.

Which symptoms are consistent with clinical findings indicative of obstructive shock?

Obstructive Shock

  • Low blood pressure can happen quickly, but the body will be trying to compensate (unlike neurogenic shock)
  • Rapid pulse.
  • Unequal breath sounds (if caused by a pneumothorax)
  • Trouble breathing.

Which of the following injuries would most likely cause obstructive shock?

Obstructive shock can be caused by cardiac (pericardial) tamponade, which is an abnormal build-up of fluid in the pericardium (the sac around the heart) that compresses the heart and stops it from beating properly, or pulmonary embolism (a blood clot in the pulmonary artery, blocking the flow of blood to the lungs)

What is the main objective of managing obstructive shock?

The goal of shock management is to get oxygen to the tissues and to the organs. This requires having enough oxygen in the blood, getting the blood to the tissues, and keeping the blood within the vasculature.

Do you give fluids for obstructive shock?

In this case, giving fluids can improve right heart filling. However, in other causes of obstructive shock, too much fluid can worsen cardiac output. Thus, fluid therapy should be monitored closely. After these stabilizing measures, further treatment depends on the cause.
