Aerochamber Size Guide: Ensuring Optimal Medication Delivery
Aerochamber selection, guided by age and facial dimensions, is crucial for effective medication delivery, maximizing benefits for infants, children, and adults alike.
What is an Aerochamber?

Aerochambers, also known as valved holding chambers, are vital medical devices used with metered-dose inhalers (MDIs). They significantly improve medication delivery to the lungs, particularly for individuals who struggle with coordinating inhalation and actuation. Essentially, an aerochamber temporarily holds the medication released from the inhaler, allowing the user to breathe it in slowly and deeply over several breaths.
This method reduces the amount of medication deposited in the mouth and throat, increasing the dosage reaching the airways. Different sizes are available – infant, child, and adult – to ensure a proper seal and optimal drug delivery based on age and facial structure. Proper use, alongside correct sizing, is paramount for maximizing therapeutic effects.
How Aerochambers Enhance Medication Effectiveness
Aerochambers dramatically boost medication effectiveness by overcoming common challenges associated with traditional metered-dose inhaler (MDI) use. Many patients, especially young children or those with coordination difficulties, struggle to inhale simultaneously with MDI activation. The chamber suspends the medication as a mist, providing a window for slower, deeper inhalation.
This reduces oropharyngeal deposition – medication lodging in the mouth and throat – and increases lung deposition. The valve system prevents medication from escaping during exhalation, ensuring more is available for subsequent breaths. Utilizing an appropriately sized aerochamber, coupled with correct technique, maximizes the amount of drug reaching the lungs, improving symptom control and treatment outcomes.
Understanding the Importance of Proper Fit
Aerochamber effectiveness hinges on a proper fit, ensuring a secure seal between the mask and the patient’s face. A poorly fitting mask allows medication leakage, diminishing the delivered dose to the lungs. This is particularly critical for infants and young children, whose facial structures are still developing.

Selecting the correct size – infant, child, adult small, or adult large – based on age and facial measurements is paramount. Consider individual anatomical variations; a ‘one-size-fits-all’ approach is ineffective. Proper mask selection minimizes leakage, maximizes drug delivery, and optimizes therapeutic benefits, leading to improved respiratory health outcomes.
