Inhaled asthma medications are often delivered by using a device called a metered dose inhaler, or "MDI." The MDI is a small aerosol canister in a plastic holder that delivers a puff of medication to the lungs.
To help make it easier for your child to use the MDI and ensure the delivery of medication gets into the lungs, your child may use a spacer chamber (with or without a mask) with the MDI. The purpose of the spacer chamber is to hold the medication released from the MDI so that your child has the time to more effectively inhale the medication. These devices are recommended for all children who have difficulty coordinating breathing and the use of the inhaler correctly (particularly children less than five to six years old).
Asthma symptoms are like the weather -- they change often and may seem unpredictable. But also like the weather, careful tracking of asthma symptoms can help identify patterns and what they may say about your asthma control.
Research has shown that tracking and rating your asthma symptoms are key steps in successfully managing asthma. One study even found that it helps keep kids with childhood asthma out of the emergency room.
Most asthma action plans track your “peak flow” (measured by a portable,...
The contents of an MDI are under pressure and are released quickly, making it difficult to coordinate inhalation of the particles. The spacer chamber suspends these particles until your child breathes in, reducing the amount of coordination required to inhale the particles, thus easing the delivery of medication into the lungs. Adults should also use a spacer chamber, especially if they have problems using the MDI. Spacer chambers can also reduce the deposition of particles in your mouth or tongue and therefore may reduce side effects from medications. Spacer chambers should not be used with a dry powder inhaler (DPI).
