Because you have asthma, COPD, or another lung disease, your doctor has prescribed medicine that you need to take using a nebulizer. A nebulizer is a small machine that turns liquid medicine into a mist. You sit with the machine and breathe in through a connected mouthpiece. Medicine goes into your lungs as you take slow, deep breaths for 10 to 15 minutes. It is easy and pleasant to breathe the medicine into your lungs this way.
If you have asthma, you may not need to use a nebulizer. You may use an inhaler instead, which is usually just as effective. But a nebulizer can deliver medicine with less effort than an inhaler. You and your doctor can decide if a nebulizer is the best way to get the medicine you need. The choice of device may be based on whether you find a nebulizer easier to use and what type of medicine you take.
Most nebulizers are small, so they are easy to transport. Most nebulizers also work by using air compressors. A different kind, called an ultrasonic nebulizer, uses sound vibrations. This kind of nebulizer is quieter, but costs more money.
Take the time to keep your nebulizer clean so that it continues to work properly.
The basic steps to set up and use your nebulizer are as follows:
