Metered-Dose Inhaler (MDI)

A Metered-Dose Inhaler (MDI) is a portable device that delivers a specific dose of medication directly into the lungs to treat conditions like asthma or COPD. It contains a pressurized canister with medication and an actuator nozzle. When you press down on the canister, a measured amount of medicine is released as a fine spray or mist, which you inhalate through your mouth. Proper technique involves coordinating inhalation with actuation for effective delivery. MDIs are convenient, quick-acting, and allow precise dosing, making them a common choice for controlling respiratory symptoms.
