Final answer:
Obstructive shock occurs when blood flow is obstructed in a significant part of the vascular system. Causes include pulmonary embolism, cardiac tamponade, stenosis of the aortic valve, and pneumothorax. Treatment involves addressing the underlying cause and may include administering fluids, using anticoagulants, and performing surgery.
Step-by-step explanation:
Obstructive shock occurs when a significant portion of the vascular system is blocked, leading to a decrease in blood flow. The causes of obstructive shock include pulmonary embolism, stenosis of the aortic valve, cardiac tamponade, and pneumothorax. Treatments for obstructive shock depend on the underlying cause and may include administering fluids intravenously, using anticoagulants, removing fluid or air from the cavities, and surgery if necessary.
