How Can Atelectasis Be Prevented?

Not smoking before surgery can lower your risk of atelectasis. If you smoke, ask your doctor how far in advance of your surgery you should quit smoking.

After surgery, your doctor may recommend that you take the following steps to fully expand your lungs:

  • Perform deep breathing exercises. These exercises are very important after surgery. While in the hospital, you may use a device called an incentive spirometer. This device measures how much air you're breathing in and how fast you're breathing in. Using this device encourages you to breathe deeply and slowly.
  • Change your position. Sit up or walk around as soon as possible after surgery (with your doctor's permission).
  • Make an effort to cough. Coughing helps clear mucus and other substances from your airways.

If deep breathing is painful, your doctor may prescribe medicines to control the pain. This can make it easier for you to take deep breaths and fully expand your lungs.

Your doctor also might suggest using positive end-expiratory pressure (PEEP) or continuous positive airway pressure (CPAP). Both devices use mild air pressure to help keep the airways and air sacs open.
