How to prevent Pulmonary Embolism ?
Preventing pulmonary embolism (PE) begins with preventing deep vein thrombosis (DVT). Knowing whether you're at risk for DVT and taking steps to lower your risk are important.
                
Exercise your lower leg muscles if you're sitting for a long time while traveling.
                
Get out of bed and move around as soon as you're able after having surgery or being ill. The sooner you move around, the better your chance is of avoiding a blood clot.
                
Take medicines to prevent clots after some types of surgery (as your doctor prescribes).
                
Follow up with your doctor.
                
If you've already had DVT or PE, you can take more steps to prevent new blood clots from forming. Visit your doctor for regular checkups. Also, use compression stockings to prevent chronic (ongoing) swelling in your legs from DVT (as your doctor advises).
                
Contact your doctor right away if you have any signs or symptoms of DVT or PE.
