Rossmax AS175 Adult Aero Spacer Valved Holding Chamber is a chamber intended to be used with metered dose inhaler (MDI) to deliver aerosol medication to your lungs as prescribed by supervision of a licensed physician and/or a respiratory therapist. The intended environments for use include the home, hospitals and clinics. This device incorporates a portable design and is easy to handle. The chamber is made of antistatic material to prevent the medication from getting stuck on the chamber walls. The device is not made with natural rubber latex and is only for single patient use. When not in use, store the device or mask in a clean place or in a clean polybag. When patients have trouble using Metered Dose Inhalers (MDIs), the medication that the MDIs dispense may end up on the back of the throat or on the roof of the mouth. Rossmax AS175 Adult Aero Spacer helps patients inhale MDI medications correctly. Spacers extend the amount of time the inhaler takes to deliver medicine. This means that the lungs absorb the medicine more slowly and smoothly. A person inhales a greater concentration of medication into their lungs. Using a spacer reduces the risk of side effects, such as oral thrush, when inhaling corticosteroids. It help the medication get straight to where it's needed in your lungs, with less medication ending up in your mouth and throat where it can lead to irritation or mild infections.
