Shortness of breath and pulmonary embolism

Severe muscle spasms caused by tetanus can interfere with or stop your breathing. Respiratory failure is the most common cause of death. The lack of oxygen will cause cardiac arrest and death. They have chest pain, and sharp pain when inhaling. The patient cannot take a deep breath, the deeper the breath, the more painful it is. The body is tired, has no energy, and is often shocked. It is caused by a large blood clot that interferes with the pumping and circulation of the heart, leading to a drop in blood pressure. A thrombus that has ruptured and is free-floating in a blood vessel can travel to another area of the body and block a blood vessel there.

If there is a thrombus in the venous system, the thrombus will travel from the veins to the right heart and then from the right heart into the main pulmonary artery and may become trapped there or continue to travel into either lung. When a thrombus lodges in the pulmonary artery, it blocks blood flow to the lungs to receive oxygen. If there is not enough blood to receive oxygen and move it to the left heart, the oxygen levels in the body drop dangerously and can cause damage to all organs in the body, including the brain and kidneys, or heart.
