Asthma Is A Major Threat To Many People

People who don't have asthma or a family member with asthma probably has an idea what a peak flow meter is.  But for anyone with breathing problems, a peak flow meter is an important measuring tool that helps to prevent complications.

Asthma is chronic disease that is hallmarked by the inflammation of the bronchial or breathing tubes, in the lungs. While there is no known specific cause for the condition, many of its triggers are well known and avoidable; and those that can’t be avoided can be well managed.

15 million adults and 5 million children in the United Stated have asthma, a chronic respiratory disease that can cause early morning or late night coughing, wheezing, chest tightness, fatigue, anxiety and shortness of breath. Asthma symptoms can be mild or serious, and they can also be life threatening during an asthma attack.

Our lungs are filled with hollow tube like passages that resemble the branches on a tree. These passages gradually become smaller and smaller ending in tiny pockets where oxygen and carbon dioxide are exchanged. 

For those with asthma, swelling in the hollow tubes makes breathing difficult and uncomfortable by preventing the air from moving freely. This inflammation causes an increased sensitivity to allergens and a host of other asthma triggers.

How Does A Peak Flow Meter Work?

A peak flow meter is a very important device for asthmatics and without it there would really be a huge gap to be filled in the world of asthma-related gadgets.  It is a small, inexpensive hand-held gadget used to monitor the airflow through the bronchi and controls the degree of airway restriction.  

It is effectively a circular tube of plastic with a mouthpiece on one end; the user then blows, as hard as they can in a sudden burst of breath, in to the tube. A slide on the top of the tube will then move along a numbered chart, giving a Peak Flow reading.

Peak flow meters usually work through a mechanism called "fast blast", because it basically measures a person's ability to push air out of his or her lungs.

Why Is It Important To Measure Your Peak Flow?

The main function of the peak flow meter is to measure an individual's maximum ability to exhale.  This ability to exhale is also known as peak expiratory flow rate.  When an individual is well and healthy, the peak flow readings are expected to be high.  

On the other hand, peak flow readings are expected to be low among patients who are unwell due to constricted airways.

The peak flow reading measurements may fluctuate every now and then and that's why doctors and patients must take note of the peak flow readings carefully so that each significant change or fluctuation in the readings can b documented.

Both the doctor and the patient can determine the extent of lung functionality, severity of the symptoms as well as the treatment options for asthma.  The height, age, and sex of an individual greatly affects the normal peak flow reading value.

Measuring the peak flow rate regularly and accurately can greatly help you in monitoring asthma.  

The measurements taken from peak flow rate readings can be used as a basis for taking asthma medications.  

As mentioned earlier, if your asthma is properly controlled, you should be able to do most things that you would normally do, including reasonably rigorous exercise.

Generally, peak flow meters can provide two ranges of measurement to assess the amount of air pushed out of the lungs.  Low range peak flow meters are used for very small children while a standard range peak flow meter is used for teens and adults.  Adults have larger airways than children that's why there is really a need to have separate peak flow meters for adults and children.

You Should Have Peak Flow Readings That Are Based On Your Lungs

How To Keep Track Of Your Readings
