Learning About How to Help Your Child Cough Up Mucus

There are several ways you can help your child cough up mucus to clear their lungs. Talk to your child's doctor or respiratory therapist. They can show you and your child how to do each technique the right way.

Here's how you can help your child cough up mucus. To help prevent reflux from the stomach, make sure that your child's stomach is empty when you do this. Before a meal or at least an hour afterward is best.

1. Set up items such as pillows and towels before you get started. You may need tissues, pillows, a thin cloth, or towels. Try different things to find the most comfortable place for you and your child to do the treatment. If you have a baby or small child, try sitting in a chair with them in your lap. An older child may do the treatment in bed.
2. Position your child. Your child's doctor or therapist will recommend positions. Each position will help to clear a different part of your child's lungs. This technique is called postural drainage.
3. Clap (percuss) your child's chest or back with your cupped hand. This loosens mucus and helps it move. Be sure the area is covered with thin clothing or a cloth. Form a "cup" with your hand. Clap on your child's chest or back at a quick and steady pace. When you clap, you should hear a hollow "popping" sound. If you hear a slapping sound, cup your hand more. Chest and back percussion are often used with postural drainage to help move the mucus.
4. Use the right amount of force and a steady beat when clapping. How much force to use while clapping, and how long you clap, depends on your child. Here are some things to consider:
   • Younger and smaller children need less force and time than older and larger children.
   • Use enough force to help clear your child's lungs, but use less if you notice signs of pain and discomfort.
   • Try using more force if your child is congested but mucus isn't coming up.
5. Apply vibrations. This will help loosen and move mucus. At the end of each position, have your child take a big breath and blow it out slowly. As they blow out, place a flat hand over your child's chest or back area. Apply a little bit of pressure and quickly vibrate your arm and shoulder muscles.
6. Have your child huff and cough. A huff is a forced breath that moves mucus higher in the lungs. This makes it easier to cough it up. Have your child take a deep breath in, hold it for 2 to 3 seconds, and then breathe it out through an open mouth with force (huff). It's much like breathing out to fog up a mirror. If any mucus comes up, have your child spit it out into a tissue.

Treatment usually takes 15 to 40 minutes per session. In general, a baby or small child who has no symptoms of congestion will need less treatment time than an older child who sounds congested and is coughing a lot.

At first, this may seem hard to do. But with help and practice, the treatment becomes easier, especially when you see that your child is breathing easier.
