How Long for a Pulmonary Embolism to Become Fatal?

A pulmonary embolism can become fatal very quickly if not treated promptly. The severity of the embolism, the size of the clot, and the individual’s overall health can all impact how quickly the condition progresses. In some cases, a large clot can block blood flow to the lungs, leading to a sudden and severe decrease in oxygen levels, which can be life-threatening within minutes. It is crucial to seek medical attention immediately if you suspect you have a pulmonary embolism to prevent any potential fatal consequences.
