Pic AirChamber is an anti-static expander chamber used to improve the absorption of medication from a pressurized inhaler. Indicated in situations of asthma and Chronic Obstructive Pulmonary Disease (COPD). The AirChamber retains the medication in the chamber until the moment of inspiration, adapting to the patient's breathing, properly transporting the medication to the respiratory tract. An asthma attack often results in restlessness and worry (especially in children): the AirChamber allows you to breathe normally while inhaling the medication and the low valve resistance maximizes airflow. Contains a low-resistance valve to allow for easy exhalation. The clear chamber allows a clear and correct view of valve movement during drug administration. Includes an expander chamber and an oval soft silicone mask. Size: S (for children under the age of 1 year). AirChamber is a CE medical device: Silicone mask is a CE 0805 medical device.
