DANAVI Spirometer

Spirometer, also known as Peak Flow Meter, is a hand-held pulmonary function measuring medical device that measures your maximum possible exhalation which is called peak expiratory flow (PEF) and forced expiratory volume in 1 second (FEV1). The accuracy meets American Thoracic Society (ATS) Standard 2005 Revision.

A peak flow meter is used to measure a person’s “peak expiratory flow”, which is a simple measure of airflow that can tell you how well you are breathing. It tells you how well air is moving through the airways in your lungs. Forced Expiratory Volume (FEV1) is a measure of the volume of air expelled in 1 second. If you have a breathing condition such as asthma, C.O.P.D., or chronic bronchitis, your physician (or other licensed health care professional) may recommend that you use a peak flow meter to watch for changes in your airflow. Your physician (or licensed health care professional) will give you a treatment plan that will tell you what actions to take when you have a change in airflow. In addition, you should record your peak flow measures as recommended by your physician (or other licensed health care professional). Reviewing peak flow measures can help you and your physician (or licensed health care professional) checks closely on your asthma or C.O.P.D. to provide the best treatment for you.

DANAVI Spirometer lets you collect and record the required data for your physicians to accurately prescribe the best treatment plan tailored to your health.
