Discharge Instructions for Pulmonary Embolism

A pulmonary embolism occurs when an embolus (clot) in the bloodstream travels through the heart and into the lungs. If the embolus becomes stuck in a blood vessel in the lungs, blood flow can be blocked. Symptoms can quickly develop and cause life-threatening heart and lung problems.

Home care

  • Take your medications exactly as directed. Don’t skip doses.

  • Ask your doctor about daily aspirin therapy.

  • Drink 6 to 8 glasses of water a day, unless directed otherwise.

  • Learn to take your own pulse. Keep a record of your results. Ask your doctor which readings mean that you need medical attention.

Lifestyle changes

  • Avoid sitting, standing, or lying down for long periods without moving your legs and feet.

  • When traveling by car, stop to get out and move around at least once every 3 hours. On long airplane, train, or bus rides, get up and move around when possible. If you can’t get up, wiggle your toes and tighten your calves to keep your blood moving.

  • Maintain a healthy weight. Get help to lose any extra pounds.

  • If you are a smoker, break the smoking habit. Enroll in a stop-smoking program to improve your chances of success.

  • Be active. Begin an exercise program. Ask your doctor how to get started. You can benefit from simple activities such as walking or gardening.
