A metered-dose inhaler (MDI) is a pressurized canister of medicine that releases a medicated mist. Inhaled asthma medicines contain a gas that helps the medicine get into your lungs. Chlorofluorocarbon (CFC) depletes the ozone layer in our atmosphere. It has been replaced in inhalers by hydrofluoroalkane (HFA). The medicine in HFA inhalers is the same as the medicine in CFC inhalers. It's the gas used to push the medicine out of the inhaler that has changed. The HFA inhaler looks just like a CFC inhaler, but is a little different. The spray comes out with less force, is warmer, and has a slightly different taste. It is not felt as much in the throat when inhaled, but you still get the right amount of medicine.
The spacer is a device that traps medicine and increases the space between the metered-dose inhaler (MDI) and the mouth. This helps your child inhale more medicine into his lungs. It also decreases the amount of medicine deposited on the back of his throat. The use of a spacer is recommended for all MDIs.
InspirEase and EZ Spacer are two brands of the collapsible bag type spacer. EZ Spacer can be used with a mask, but InspirEase cannot.
The mouthpiece should be washed daily with warm water and dried. (Do not put it in the dishwasher.) The manufacturer does not recommend washing the reservoir bag. The bag should be replaced when it wears out, or once every month.
