Understanding Pulmonary Embolism
A pulmonary embolism (PE) is a medical emergency. It occurs when a blood clot, usually traveling from elsewhere in the body, becomes lodged in the pulmonary arteries—the vessels that carry blood from your heart to your lungs. When these arteries are blocked, blood flow to the parts of the lungs that need it is restricted, which can cause difficulty breathing and cause oxygen levels to drop.
Key Symptoms to Watch For
- Sudden shortness of breath or difficulty breathing.
- A sudden chest pain that worsens when taking a deep breath or coughing.
- A rapid heart rate (tachycardia).
- Coughing up blood or coughing more than usual.
Treatment and Care Options
Treatment for a pulmonary embolism is urgent and depends on the severity of the clot. The primary goals are to prevent the clot from getting larger and to help the blood thin out. Treatment typically involves specialized medication, such as anticoagulants (blood thinners) which can be taken orally or through an injection. Patients may also require oxygen therapy, supplemental breathing support, or, in severe cases, blood thinners administered via IV drips. Rest and activity recommendations will follow the initial treatment phase.
What Causes Pulmonary Embolism?
A pulmonary embolism happens when a blood clot travels to the arteries in the lungs. These clots most often originate in the deep veins of the legs, a condition called deep vein thrombosis (DVT), and travel through the bloodstream until they lodge in the pulmonary arteries.
- Deep Vein Thrombosis (DVT): Clots forming in the legs or pelvis.
- Immobility: Long periods of sitting or lying down (such as during long flights or bed rest).
- Underlying Health Conditions: Conditions like cancer or recent surgery can increase clotting risk.
