using_a_nebulizer_can_help_people_with_asthma_during_a_sleep_studyWhen people think of treatments for restrictive lung diseases and common disorders like asthma, they may imagine way to treat these is by using an inhaler with a spacer.

However, in some cases, a nebulizer may be used, and it can be part of your sleep study experience if you have problems breathing both day and night.

What is a nebulizer?

A nebulizer (its root word is nebulous, meaning “cloud”) is a common treatment for a variety of lung problems. This device processes medication in such a way as to make it safe to inhale through a mouthpiece or mask. 

How a nebulizer works

the_alveoli_are_blocked_by_mucus_and_swelling_during_an_asthma_attackThe main airways of the lungs are called bronchi. These branch off into extremely small passageways (bronchioles) which lead to even tinier, balloon-like air sacs, at the end of the bronchioles called alveoli.  

When a person encounters restricted breathing, their bronchioles and alveoli become swollen and inflamed, making it difficult to breathe.

A nebulizer uses a small compressor to deliver air into a chamber attached to a mouthpiece or mask. Inside that chamber, medication is placed to be nebulized, which means the liquid medicationnebulization_uses_compressed_air_to_break_down_liquid_medications_into_a_mist_that_can_be_inhaled—which is made up of small enough particles to be transferable to the smallest parts of the respiratory system— will be transformed into a mist which can then be inhaled into the lungs in order to treat inflammation. 

When breathing is difficult for some people that suffer from a variety of lung problems, a nebulizer can be a first line of defense prescribed by physicians. 

Who might use a nebulizer while in the sleep lab?

The following kinds of medical conditions might warrant the use of a nebulizer during a sleep study:

  • COPD: The medications prescribed for people with chronic obstructive pulmonary disease (COPD) are often delivered by way of a nebulizer during sleep tests.
  • Overlap syndrome: This is a condition in which a patient has both obstructive sleep apnea (OSA) and COPD. It might be useful to use a nebulizer to help improve breathing problems caused by COPD and to help the relax the patient with overlap syndrome prior to, or at any time during, their study.
  • Asthma: Some people have frequent acute asthma attacks; using a nebulizer to dispense their medication during a sleep study can quickly resolve their breathing concerns.
  • Cystic fibrosis (CF): In this progressive, genetic disease, persistent lung infections make it difficult for people with CF to breathe due to a thick layer of mucus that builds up in the lungs, pancreas, and other organs.  It's likely that a patient with CF will need some form of nebulization therapy during a sleep study.
  • Other illnesses that benefit from an upper airway delivery of medication by nebulization: Because this system of medication delivery makes it easy to quickly treat someone with severe medical problems, it can be used for other applications besides breathing disorders if it will improve the patient's ability to sleep better during a test. Such medical problems include bronchiectasis, AIDS-associated infections, terminal disease, and other concerns.

What medications can be delivered using a nebulizer?

The following medications are just a few of the many drugs that can be inhaled through a specialized nebulizer:

  • albuterol, levalbuterol, pirbuterol

  • arformoterol, formoterol

  • budesonide
  • cromolyn sodium

  • ipratropium

  • metaproterenol 

Note: Medications that can only be dispensed through a nebulizer include pentamidine, ribavirin, rhDNAase, and tobramycin.

Are there risks to using a nebulizer as your medication delivery system?

The greatest risk you have with using a nebulizer during a sleep study is the increased chance for developing a lung infection if the chamber isn't completely sterile before use. However, sleep labs work hard to maintain high standards for cleaning and disinfecting their devices, so the chance of this actually happening is extremely slim.  

How to use a nebulizer

a_nebulizer_is_a_simple_device_for_delivering_inhaled_medications.jpgYou may already know how to use one, but a hospital sleep clinic referral from a pulmonologist might order the use of a nebulizer prior to or during a sleep study, which may be different from your particular experience.

Don't worry, however; the sleep specialist you work with will help you every step of the way.

Here's a basic procedure for using a nebulizer:

  1. The medication chamber is connected by a hose to the main compressor.
  2. Medication is added to the chamber of the nebulizer.
  3. The hose and mouthpiece are attached to the chamber.
  4. The user places the mouthpiece in the mouth (or the mask over the nose and mouth). 
  5. The user breathes through the mouthpiece or the mask until all the medicine has been inhaled, usually over 15 minutes' time. 
  6. If it's difficult to use the mouthpiece without breathing through the nose, a clip can be used to seal the nostrils to ensure all medication is inhaled through the mouth. 

The best durable medical equipment providers (also known as DME) can help patients who need nebulizers in the lab to use them and may even be able to train them to use these devices at home.
