What are nebulizers?

A nebulizer is a special device that warms or otherwise changes a liquid solution into a fine mist that’s easy to inhale. Some people call nebulizers breathing machines. Nebulizers are useful in treating certain respiratory conditions. Doctors often use them for babies. They allow infants to take in medication while breathing as they normally would. When a baby breathes in the mist from a nebulizer, the medicine can go deep into their lungs where it can work to make breathing easier. Doctors prescribe nebulized medications, but you can learn how to give these medications to your baby at home if needed.

What conditions do nebulizers treat?

Doctors may prescribe nebulizers for chronic conditions in infants. Asthma, for example, is a condition that causes an immune response that irritates the airways. Other conditions a doctor may prescribe a nebulizer for include:
  • Croup. Croup is the result of one of the viruses that causes the common cold. It causes airway swelling that leads a child to develop a barking cough, runny nose, or fever.
  • Cystic fibrosis. This genetic disease can cause thick mucus to build up in the airways, clogging them and making it harder to breathe.
  • Epiglottitis. This rare condition is a result of the Haemophilus influenzae type B bacteria that can cause pneumonia. It causes severe airway swelling that leads to an abnormal, high-pitched sound when breathing.
  • Pneumonia. Pneumonia is a severe illness involving inflamed lungs. It usually requires hospitalization in babies. Symptoms include fever, shortness of breath, and changes in a baby’s alertness.
  • Respiratory syncytial virus (RSV). RSV is a condition that often causes mild, coldlike symptoms. While severe symptoms aren’t common in older children, infants can develop inflammation of the small airways (bronchiolitis).
Nebulizers can be an alternative to inhalers. These devices deliver short bursts of medication when a person inhales. Nebulizers deliver medication over a course of time, usually 10 to 15 minutes. They don’t require a baby to cooperate to take the medicine in. While inhalers can be fitted with masks and used even with young infants, nebulizers are preferred, depending on the medication and why it’s being used.

How does a nebulizer work?

Two different power options exist for nebulizers:
  • a jet or compressor nebulizer
  • an ultrasonic unit
A compressor nebulizer has a piston-style motor that uses compressed air to create the mist. This compressor type can be loud as it works to create the mist. It often has adjustable particle sizes and can vary in terms of treatment time. An ultrasonic nebulizer generates ultrasonic vibrations that transform water into a mist for delivering the medication. This method means the nebulizer is very quiet compared to a jet compressor. An ultrasonic nebulizer will typically deliver a treatment in about six minutes. However, not all medications can be delivered with an ultrasonic nebulizer. It heats the medicine, which may affect the quality of some medications. If you’re considering an ultrasonic nebulizer, always talk to your child’s doctor first to make sure you can use an ultrasonic nebulizer for the treatments.

Delivery methods

Nebulizer manufacturers have worked to make nebulizers more child-friendly. Some of the delivery methods include a face mask or a pacifier attachment for infants. A mask is preferred for infants, because they often breathe through the nose instead of the mouth. As a child gets older (usually age 6 or older), they may use a handheld mouthpiece instead of a mask. This allows more of the medication to enter the lungs instead of escaping around the mask.

Types of medications

Doctors may prescribe different medications that a nebulizer can deliver. Examples of these medications include:
  • Inhaled antibiotics. Some antibiotics are available via nebulizer treatment. An example is TOBI. It’s a form of tobramycin used to treat certain bacterial infections.
  • Inhaled beta-agonists. These medications include albuterol or levoalbuterol. They’re used to relax the airways and make breathing easier.
  • Inhaled corticosteroids. These can treat inflammation due to asthma.
  • Dornase alfa (Pulmozyme). This medication helps treat cystic fibrosis by loosening thick mucus in the airways.

Step-by-step guide

While some of the elements of using a nebulizer depend on the specific type, here’s a general example of the nebulizer process:
  1. Collect the medication for the nebulizer. Some are available in liquid form that have the medicine added. Others are a liquid or powder that must be mixed with sterile water or saline solution. Read the directions carefully before pouring the medication in the cup.
  2. Connect one end of the tubing to the cup of medication and the other to the nebulizer.
  3. Connect the mask or pacifier to the cup.
  4. Hold the mask to your child’s face. While many of the infant masks come with strings to put around a baby’s head, most babies don’t tolerate these strings very well. It may be easier to gently hold the mask touching the child’s face and cover their nose and mouth.
  5. Turn the nebulizer on.
  6. Hold the mask to your child’s face while the treatment bubbles and creates a mist inside the mask.
  7. You’ll know when the treatment is complete when the mist becomes less noticeable and the little cup appears almost dry.
  8. Clean the mask and nebulizer after each use.

Tips for using with babies

Babies can be squirmy, which makes administering nebulizer treatments a challenge. Here are some tips that can help:
  • Use the nebulizer at times your baby is more likely to be sleepy and tolerate treatments better. This includes after meals, before a nap, or at bedtime.
  • If noise seems to bother your baby, place the nebulizer on a towel or rug to reduce noise from the vibrations. Using longer tubing can also help, because the noisiest part isn’t close to your baby.
  • Hold your child upright in your lap during the treatment. Sitting upright helps deliver more medication throughout the lungs because they can breathe more deeply.
  • Swaddle your baby if they’re more comfortable that way during treatment.
If you have specific questions or concerns related to giving your baby a nebulizer treatment, talk to your child’s doctor.

Cleaning the nebulizer

It’s very important you clean the nebulizer after every time you use it. Bacteria and fungi thrive in warm, moist environments. If the nebulizer isn’t cleaned, these germs can build up. When you use an unclean nebulizer on your baby, the bacteria and fungi can be delivered directly to your baby’s lungs. If you don’t have special instructions that came with the nebulizer regarding cleaning, here are general guidelines:
  1. Unscrew the plastic portion of the device. Soak it in warm, soapy water for at least 15 minutes.
  2. If you like, you can also disinfect the nebulizer with 2 teaspoons of chlorine bleach with 2 cups of tap water. Always keep disinfectants out of reach of children.
  3. After letting it soak, rinse thoroughly. Allow it to air-dry.
  4. Store the nebulizer in a clean, dry environment when not in use.
Read the manufacturer’s instructions carefully as to when you should change the nebulizer’s filters. If any part of the nebulizer unit appears dirty, replace it or clean it.

What are the pros and cons?

Some of the pros and cons for nebulizer treatments include:
Effective method to deliver aerosolized medications.Can spread contaminated mist if not properly cleaned between uses.
Features delivery routes, such as pacifiers or masks ideal for infants.Takes longer than an inhaler, and may require replacement.
Available in portable options that are easy to travel with.Can result in some side effects, depending on the medication used.

What’s the cost?

Nebulizers are available for purchase from most major retailers and at drugstores. Many insurance companies will often cover a portion or all of the costs of nebulizers, as they’re considered durable medical equipment with a doctor’s prescription. However, it’s best to talk to your insurance company before purchasing a nebulizer to ensure insurance will cover the costs. Here are some examples of nebulizers you can buy online.


Nebulizers are a safe and effective way to deliver medications to an infant. Always contact your child’s doctor if for any reason your child appears to have more difficulty breathing after a breathing treatment. Some infants can have the opposite expected reaction following a treatment. Reviewing the possible side effects with your child’s doctor can help you identify these symptoms more quickly.
