Background

Millions of individuals with asthma and chronic obstructive pulmonary disease (COPB) depend on inhalers and spacers for the delivery of medication into their lungs. Despite this, achieving a proper inhalation flow rate (rate at which the patient inhales) is challenging and requires practice in order to maximize the medication efficiency. In order to address this issue, a device was made to guide the users towards a proper inhalation flow rate through a user feedback LED system.
