Front chambers : why are they important:?
An aerosol pre-chamber is important because it helps the medication get into the lungs better. Without a pre-chamber, much of the medicine ends up in the mouth and throat, reducing its effectiveness. The pre-chamber allows the particles of the drug to be better distributed and enter the airways more slowly, allowing them to penetrate deeper into the lungs. It also reduces the risk of side effects such as fungal infections in the mouth due to less drug residue in the throat. In addition, using a pre-chamber is easier for patients who have difficulty properly coordinating their breathing with the activation of the inhaler.
How to use the pre-chamber:
Shake the inhaler:Shake the aerosol inhaler well to mix the medicine.
Place the inhaler in the pre-chamber:Firmly attach the inhaler to the back of the pre-chamber.
Exhale: Exhale slowly and completely away from the pre-set chamber.
Inhale through the pre-set chamber: Place the mouthpiece of the pre-set chamber between the lips and seal the lips tightly.
Deliver a puff: Press the aerosol to release a puff into the pre-set chamber.
Inhale slowly: Inhale slowly and deeply through the pre-set chamber so that the drug reaches the lungs.
Hold breath: Hold the breath for 5 to 10 seconds, then exhale slowly.
Repeat if necessary: Repeat the steps if more than one puff is prescribed.
After use: Rinse your mouth with water if the inhaler contains a corticosteroid to prevent side effects in the mouth.
From the literature
Molimard, M., & Raherison, C. (2018) "Poor adherence to inhaler usage instructions is associated with suboptimal clinical control in asthma" Chest, 153(4), 908-917.
This is a study published in the journal Chest. The text emphasizes that many patients use inhalers incorrectly, making treatment less effective. Education and repeated instruction are recommended to help patients improve their technique to increase the effectiveness of treatment.
How often will I be reimbursed for the pre-chamber?
A pre-chamber for inhalation medication is usually reimbursed once every 12 months from basic insurance, provided it has been prescribed by a doctor. However, it can vary by health insurer and type of policy, so it is always wise to check the terms and conditions of your own health insurance. Also keep in mind the deductible, which may be drawn on first before full reimbursement.
