How Is Asthma Diagnosed?

Asthma is a medical condition that makes breathing difficult. During asthma flareups and attacks, the patient's airways become narrowed, swollen, and also produce excess mucus. In addition to making breathing difficult, the condition can trigger shortness of breath, wheezing, and coughing. Some individuals with asthma experience symptoms as a minor nuisance, though some deal with symptoms severe enough to be life-threatening and interfere with day-to-day activities. Though asthma doesn't have a cure, the symptoms are controllable. Patients will need to work with their doctor on an ongoing basis to make sure the symptoms continue to be controlled through medication. The symptoms can vary widely from person to person.

There are several ways that asthma can be diagnosed. The severity of symptoms and the type of asthma will affect the diagnostic methods used. Learn more about diagnosing asthma now.

Use Of A Peak Flow Meter

Peak flow meters are portable and hand-held devices that measure an individual's capacity to push air from their lungs. They are available in two ranges. The first, called a low-range meter, is designed for use by small children. Meanwhile, a standard-range is used for adults, teenagers, and older children. Because adults have larger and more developed airways than small children, they need a wider range of measurements. In addition to being used for the original diagnosis of asthma, peak flow meters are often helpful after patients receive their diagnosis. If individuals have been recently diagnosed or take daily medicine to control their asthma, the use of a peak flow meter helps with their day-to-day management. Peak flow meters can be used for asthma management in individuals aged five years and older. In addition, some individuals who have chronic bronchitis or emphysema might benefit from using a peak flow meter.
