What is obstructive shock example?

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

What can cause obstructive shock?

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.

What is the pathophysiology of shock?

Pathophysiology of Shock. The fundamental defect in shock is reduced perfusion of vital tissues. Once perfusion declines and oxygen delivery to cells is inadequate for aerobic metabolism, cells shift to anaerobic metabolism with increased production of carbon dioxide and elevated blood lactate levels.

What are the signs and symptoms 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.

How is obstructive shock diagnosed?

Imaging studies are crucial: Chest radiographs may show pneumothorax. Computed tomography (CT) angiography may confirm pulmonary embolism. Ultrasonography may detect or suggest cardiac tamponade, heart tumors, intracardiac thrombosis, pneumothorax, and venous thrombosis associated with pulmonary embolism.

How does obstructive shock affect hemodynamics?

Because obstructive shock impedes forward flow, cardiac output is greatly diminished, and the clinical signs and symptoms can resemble those of hypovolemic and cardiogenic shock, depending on the specific cause.

What are the complications of obstructive shock?

Obstructive shock

• pneumothorax (collapsed lung)
• hemothorax (blood collects in the space between the chest wall and lung)
• cardiac tamponade (blood or fluids fill the space between the sac that surrounds the heart and the heart muscle)

What are the 4 types of shocks?

The main types of shock include:

• Cardiogenic shock (due to heart problems)
• Hypovolemic shock (caused by too little blood volume)
• Anaphylactic shock (caused by allergic reaction)
• Septic shock (due to infections)
• Neurogenic shock (caused by damage to the nervous system)

What are the 7 types of shock?

18.9A: Types of Shock

• Hypovolemic Shock.
• Cardiogenic Shock.
• Obstructive Shock.
• Distributive Shock.
• Septic.
• Anaphylactic.
• Neurogenic.

What are the signs of neurogenic shock?

Neurogenic shock symptoms

• dizziness.
• nausea.
• vomiting.
• blank stares.
• fainting.
• increased sweating.
• anxiety.
• pale skin.

What are the symptoms of neurogenic shock?

What are signs and symptoms of obstructive shock?

Signs and symptoms of obstructive shock begin to show when the heart fails to pump enough blood to the rest of the body. Some of the first signs that are noticeable involve the skin, such as excessive sweating, clamminess, reduced temperature and a general paleness.

What does Obstructive shock mean?

Obstructive shock. Jump to navigation Jump to search. Obstructive shock is a form of shock associated with physical obstruction of the great vessels or the heart itself.

What are the causes and signs of distributive shock?

Pancreatitis may be another cause of distributive shock; expect symptoms of abdominal pain that radiate to the back, as well as nausea and vomiting. Burns also have been described as a cause of distributive shock. Adrenal insufficiency
