Question

what is the type of inhaler that provides a self - administered dose with a propellant in a canister?
○intermittent positive pressure breathing therapy (ippb).
○continuous positive airway pressure (cpap).
○metered - dose inhaler (mdi).
○nebulizer.

Explanation:

A metered - dose inhaler (MDI) is a device that delivers a pre - measured dose of medication. It contains a propellant in a canister. When activated, it releases a fine mist of the drug. Intermittent positive pressure breathing therapy (IPPB) is a form of respiratory therapy that uses positive pressure to deliver air into the lungs. Continuous positive airway pressure (CPAP) is a treatment for sleep apnea that provides a constant flow of air. A nebulizer is a device that turns liquid medication into a mist but does not typically use a canister with a propellant in the same self - administered, metered - dose way as an MDI.

Answer:

Metered - dose inhaler (MDI).
