This article covers the signs and diagnostic methods for pulmonary embolism, emphasizing early detection and treatment options. Recognizing symptoms like shortness of breath and chest pain, along with understanding diagnostic tools such as imaging and blood tests, can save lives. Prompt medical intervention is crucial for favorable outcomes.

Pulmonary embolism happens when a blood clot blocks arteries in the lungs, often originating from blood clots in the legs. These clots, mainly from deep vein thrombosis, can travel to the lungs, causing partial or complete blockage. Risk factors include cancer, obesity, age, and genetic factors. If untreated, it can severely affect oxygen supply and lead to life-threatening complications.

Early detection is essential, as symptoms can be subtle. Common signs include shortness of breath, chest pain, rapid breathing, coughing blood, dizziness, irregular heartbeat, skin discoloration, confusion, swelling of limbs, and occasional fever. Diagnostics involve imaging tests like pulmonary angiography, D-dimer blood tests, ECG, ventilation/perfusion scans, chest X-rays, and leg ultrasounds. Treatments consist of anticoagulants, thrombolytic drugs, or surgical procedures. Immediate medical attention saves lives.
