Examples of obstructive shock
What are the three most common examples of obstructive shock?
Examples include: A large blood clot in your pulmonary artery. Fluid around your heart. High pressures in your chest because of a lung injury such as a tension pneumothorax.
What is the most common cause of obstructive shock?
Obstructive Shock Overview:
The most common causes of obstructive shock in children are tension pneumothorax, pulmonary embolism, and cardiac tamponade. There are also several congenital abnormalities that can cause obstructive shock. Examples include critical aortic stenosis and coarctation of the aorta.
What are signs of obstructive shock?
What are the signs and symptoms of obstructive shock? Individuals with obstructive shock typically experience respiratory distress and may present with tachycardia, hypotension, tachypnea, air hunger (i.e., an extreme need to breathe), and chest pain.
Is pulmonary embolism an obstructive shock?
Obstructive shock is one of the four types of shock, caused by a physical obstruction in the flow of blood. Obstruction can occur at the level of the great vessels or the heart itself. Causes include pulmonary embolism, cardiac tamponade, and tension pneumothorax. These are all life-threatening.
Is hypovolemic shock obstructive?
Hypovolemic shock is a condition of inadequate organ perfusion caused by loss of intravascular volume, usually acute.

|---|---|---|
| Obstructive | 1% | 2% |
Which of the following injuries would create an obstructive shock situation?
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)
Is cardiogenic shock obstructive 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 obstructive shock EMT?
Obstructive shock occurs when there is a physical obstruction in the heart or blood flow that causes a decrease in cardiac output. A common cause of obstructive shock is cardiac tamponade.
What are the 4 types of shock?
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 is obstructive shock EMT?
Obstructive shock occurs when there is a physical obstruction in the heart or blood flow that causes a decrease in cardiac output. A common cause of obstructive shock is cardiac tamponade.
What are common causes of cardiogenic shock?
Most often the cause of cardiogenic shock is a serious heart attack. Other health problems that may lead to cardiogenic shock include heart failure, which happens when the heart can’t pump enough blood to meet the body’s needs; chest injuries; and blood clots in the lungs.
How does a pulmonary embolism cause obstructive shock?
In the case of an acute pulmonary embolism an intravascular occlusion results in an acute increase of the right ventricular afterload. In the case of a tension pneumothorax, an obstruction of the blood vessels supplying the heart is caused by an increase in extravascular pressure.
What are the 4 types of shock?
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 4 stages of cardiogenic shock?
There are four stages of cardiogenic shock: initial, compensatory, progressive, and refractory. During the initial stage, there is diminished cardiac output without any clinical symptoms.
Is bradycardia a cardiogenic shock?
This is simple math. Cardiogenic shock is defined as inadequate cardiac output to support organ function. Some patients can compensate for low cardiac output without developing shock. However, with increasingly severe bradycardia, there should be an increasing concern for cardiogenic shock.
