    video quality: regular | high

    To use a metered-dose inhaler, the patient shakes the inhaler and removes the cap. The patient exhales completely, then brings the inhaler to her mouth and breathes in slowly while pressing the top of the inhaler. She continues to inhale as a puff of medicine sprays out. The patient then holds her breath and subsequently exhales again.
