Postural Drainage

Postural drainage is a way to change your body position to help your lungs drain. If you have a long-term (chronic) lung problem associated with excessive mucus, or you have increased mucus from an infection, lying with your chest lower than your belly (abdomen) can help loosen and drain extra mucus from your lungs. The guidelines below will help you know what to do.

General guidelines

Check with your healthcare provider before trying this therapy.
Find positions that are comfortable for you. You can lie on a bed or on the floor, using pillows. Try some of the positions that are described below.
Stay in each position for at least 5 minutes.
When you feel the urge to cough, sit up and do controlled coughing.
Make sure to do postural drainage before meals or at least 90 minutes after eating. This helps prevent vomiting.
If your healthcare provider prescribed medicines such as a bronchodilator or inhaler, ask how long to wait to do postural drainage after using the medicine.
Sometimes postural drainage is used along with other therapies such as chest percussion, vibration, or use of a flutter valve. Talk with your healthcare provider before you combine different treatments together.

When not to do postural drainage

Always talk with your healthcare provider before starting postural drainage. Don't try this therapy if you:

Have mild pain when you are in certain physical positions
Are coughing up blood
Have rib fractures
Are using blood-thinning medicines
Have vertebral fractures or osteoporosis

Try this position to drain the front of your lungs.

Lie on a slanted surface with your chest lower than your hips.
Place a small pillow under your head. Put 2 pillows under your bent knees.
Rest your arms at your sides and breathe in through your nose and out through your mouth. Remember: Always breathe out for longer than you breathe in. This allows your lungs to empty as much as possible.
