Peak Flow Meter
Peak Flow Meter
A Peak Flow Meter (pronunciation: /pi:k floʊ ˈmi:tər/) is a portable, inexpensive, hand-held device used to measure how air flows from your lungs in one fast blast. It is an integral part of the management of Asthma and other chronic obstructive pulmonary diseases (COPD).
Etymology
The term "Peak Flow Meter" is derived from its function. "Peak" refers to the maximum point, "Flow" refers to the movement of air, and "Meter" refers to the device that measures this flow.
Usage
The Peak Flow Meter is used by patients to monitor their ability to expel air from their lungs. It can help signal a possible asthma attack even before symptoms appear, measure the severity of asthma, and help determine when to adjust medication or seek medical attention.
