Predict and measure his asthma

The peak expiratory flow rate is a measure of the breath when air soon resumes bronchus. Simple, easy and fast, this measure is necessary to follow the evolution of the disease and adapt the treatment. Regular measurements can also predict a crisis.

The dynamics of the breath is an essential parameter in asthma because the reduction of the calibre of the bronchi characterizing the asthma attack must be quantifiable right away. The comparative measurement of respiratory volumes as well as respiratory force in crisis and in normal times is therefore a necessity for monitoring and the adaptation of an asthma treatment.

Principle (e) t use on peak flow-meter
The peak expiratory flow (PEF) is a measure of the breath through the air flow that a subject is able to expel from his lungs as soon as possible during a forced expiration. In crisis, this throughput decreases significantly.

The measuring device is called “PeakFlow”. This is a tube with a mouthpiece. A graduated slider from 0 to 500, traversed by a small mobile arrow gives the measure of the possible maximum breath. The device is small enough to fit in a pocket. It costs 28-€38 uros depending on the model. It can be used from the age of 5 years in a child who it will be carefully explained the use of the device. Some electronic models allow to memorize your DEP over several days and thus determine the course of the disease.

A rigorous measurement technique
-The cursor is free, set position 0, vents are cleared;
-The patient is standing, the chest is inflated as much as possible;
-The tip is placed in the mouth, tightly;
-Expiry must be the most foryou possible.
-Do not blow as in a blowgun.
-The measure is immediate and must be repeated three times, the value recorded on the logbook in asthma.

Interest of the measure
The effectiveness of the treatment is instantly measurable. Adaptation of the useful doses can be done directly by a patient well trained in the technique.
