What is meant by obstructive shock?
What is meant by 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.
How do you know if you have 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 does obstructive shock occur?
Obstructive shock occurs when blood can’t get where it needs to go. A pulmonary embolism is one condition that may cause an interruption to blood flow. Conditions that can cause a buildup of air or fluid in the chest cavity can also lead to obstructive shock.
Is obstructive shock the same as cardiogenic shock?
Causes. Typical causes of traumatic hypovolemic shock are large surface burns, chemical burns, and deep skin lesions. The preclinical and clinical treatment of hypovolemic shock consists of immediate intravascular volume replacement (fluid resuscitation) with balanced crystalloids (recommendation grade: B)
Who gets Obstructive shock?
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 causes obstructive shock in the presence of a tension pneumothorax?
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 most common signs and symptoms of shock?
Signs and symptoms of shock vary depending on circumstances and may include:
- Cool, clammy skin.
- Pale or ashen skin.
- Bluish tinge to lips or fingernails (or gray in the case of dark complexions)
- Rapid pulse.
- Rapid breathing.
- Nausea or vomiting.
- Enlarged pupils.
- Weakness or fatigue.
What organs are affected by shock?
A drop in blood pressure reduces the flow of oxygen and nutrients to a person’s vital organs such as their brain, heart and lungs. If the blood flow is not restored, the person may die from complications due to lack of oxygen supply to major organs (hypoxia).

How do you treat obstructive shock?
The definitive treatment for obstructive shock caused by tension pneumothorax is needle decompression and chest tube placement to the affected area.
What happens if you go into shock at the Mayo Clinic?
By Mayo Clinic Staff. Shock may result from trauma, heatstroke, blood loss, an allergic reaction, severe infection, poisoning, severe burns or other causes. When a person is in shock, his or her organs aren’t getting enough blood or oxygen. If untreated, this can lead to permanent organ damage or even death.
Is obstructive shock a medical emergency?
By definition, obstructive shock is considered a serious medical emergency and should be treated as soon as humanly possible, as it could be potentially fatal. Obstructive shock occurs when the heart endures insufficient diastolic filling (when the heart is supplied with a fresh stream of blood).
What is the pathophysiology of obstructive shock?
Obstructive shock occurs when the heart endures insufficient diastolic filling (when the heart is supplied with a fresh stream of blood). Without regular diastolic filling, the heart can’t adequately perform its cardiac functions, which means that fresh supplies of blood won’t be pumped to the other organs in the body.
Why does the heart go into shock when there is an obstruction?
This lack of blood flow to the heart is caused by a major obstruction, which causes the organs and cells in the body to go into shock because they’re being deprived of the oxygen and vital nutrients they require to function at full capacity. What causes obstructive shock?
