How does pulmonary embolism cause death?

A pulmonary embolism (PE) can cause a lack of blood flow that leads to lung tissue damage. It can cause low blood oxygen levels that can damage other organs in the body, too. A PE, particularly a large PE or many clots, can quickly cause serious life-threatening problems and, even death.

Are all pulmonary embolisms fatal?

How quick is death from pulmonary embolism?

Of 162 patients, 44 suffered sudden death (within 24 hours of onset). Among these, 28 patients died within 1 hour and 9 within 1 to 24 hours. In the remaining seven patients, the time until death could not be determined because the subject was detected postmortem.

What is the survival rate of a pulmonary embolism?

CONCLUSION: Patients with PE who received mechanical ventilation, cardiopulmonary resuscitation, and thrombolytic treatment had very high mortality rates of 80, 77 and 30\% respectively. However, patients stable enough for diagnostic procedures as Spiral CTs and V/Q-Scans had mortality rates of 1 to 2\%.

How serious is pulmonary embolism?

The clot blocks the normal flow of blood. This blockage can cause serious problems, like damage to your lungs and low oxygen levels in your blood. The lack of oxygen can harm other organs in your body, too. If the clot is big or the artery is clogged by many smaller clots, a pulmonary embolism can be fatal.
