Good metered dose inhaler (MDI) technique is described as sitting or standing upright with the head slightly tilted back, exhaling fully, and then inhaling slowly and deeply as you activate the MDI. Common mistakes include: not exhaling fully; not inhaling deeply enough; inhaling too quickly, and not activating the MDI at the proper time.
This study will use the Respimetrix device with placebo to assess a patient's inhaler technique, provide training to patients who demonstrate poor inhaler technique, and remotely track a subject's breathing ability over time.
