Brief summary
To Determine whether use of the Respimetrix flow test device a) can determine good versus poor inhaler techniques, and b) the effects of the inhaler training on technique.
Detailed description
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.
Interventions
DEVICERespimetrix
The Respimetrix device has a low resistance airflow sensor with an inhaler to measure patients inspiratory airflow and volume. This device will thereby provide quantifiable measures of lung function and bronchodilator delivery.
