What Does Flow Spirometer Mean?
A flow spirometer refers to an oral device that measures the expiratory force of the lungs following a deep inhalation of breath. The flow spirometer determines the relative health of the lungs by using a standardized color-coded system of green, yellow, and red indicators that provide comparative values based on the expulsion of breath from the lungs. Flow spirometers are routinely used for diagnosing asthma and/or chronic obstructive pulmonary disease (COPD), and consistently monitoring their severity either by patients themselves or by a qualified clinician.
