1. A nebulizer handset or set, the component that is filled with liquid medication to create a mist or aerosol.
2. A compressor, a jet nebulizer needs an air source to help turn the liquid medication into a mist. The nebulizer is connected to the compressor by tubing. Compressors can be electrically or battery powered. Most compressors have an air filter that should be checked periodically and replaced according to the manufacturer’s instructions. Often times, the term nebulizer is used to refer to both the nebulizer and compressor together.
3. For newer nebulizer technology such as the eRapid nebulizer, components include a nebulizer handset and an electronic controller called eBase.
How a Jet Nebulizer & Compressor Work Together to Turn Liquid Medication into an Aerosol Mist:
1. The jet nebulizer attaches to the compressor by a connection tubing. Once the compressor is turned on, compressed air flows from the compressor through the connection tubing to the bottom of the nebulizer and up through a jet nozzle inside the nebulizer. The flow of air through the jet nozzle creates a vacuum that pulls the liquid medication up through a small tube where it comes in contact with the air stream.
2. As the liquid medication flows out of the tube the air stream from the compressor breaks the liquid medication into a very fine aerosol mist that is able to remain suspended in the air stream.
3. The medication aerosol mist is then carried by the air stream to a baffle. The baffle is like a wall that breaks the fine medication mist into an even smaller (microscopic) size that allows the medication to be inhaled into the lungs.
Even though there are excellent treatments for asthma, it is still a serious disease that affects more than 25 million Americans and causes nearly 2 million emergency room visits ever year. With proper asthma treatment, most people with asthma can enjoy a full and active lifestyle. Yet inadequate asthma treatment limits the ability to exercise and be active. Poorly controlled asthma can lead to multiple visits to the emergency room and even hospital admission, which can affect quality of life and performance at home, school, and work.
1. The nozzle insert in the nebulizer is missing.
2. Nozzle blocked (also possible with the LC SPRINT Nebulizer). Check the nozzle first. If there are crystalline deposits (e.g. lime residue) in the nozzle, it may be possible to remove them simply by squeezing the flexible nozzle with your thumb (however, this only works with the LC SPRINT nozzle because it is flexible). For more stubborn blockage, it often helps to clean the nozzle again by boiling the nebulizer.
3. Not enough medication in the nebulizer. Make sure that the medication in the nebulizer reaches the fill mark. Minimum: 2ml, Maximum: 8ml.
If the child is able to use the mouthpiece (by age 4 or 5):
1. Have the child exhale; place the mouthpiece into the child’s mouth. Be sure that the lips seal around the mouthpiece;
2. Depress MDI, and then instruct the child to breathe in slowly and deeply through their mouth (not through the nose);
3. To confirm inhalation watch or place your hand on the child’s chest to feel the child’s chest rise.
4. If possible, instruct the child to hold their breath for 10 seconds or for as long as is comfortable.
5. Repeat steps a through d with each MDI puff of medication.
The key difference between a spacer and valved holding chamber (VHC) is a VHC uses a valve, which allows aerosol medication to stay suspended inside the chamber for a short time period. The valve only opens on inhalation and does not allow one to exhale into the device. A VHC also slows the speed of the MDI aerosol. In addition, the need for coordinating pressing the MDI and inhalation is no longer necessary because the aerosol medication stays suspended in the chamber. VHCs are preferred over spacers for this reason. The VORTEX Non-electrostatic Valved Holding Chamber is a commonly used valved holding chamber.
