For asthmatics, measurement of expiratory flow to follow the progression of the disease. This tracking is an indicator of the effectiveness of the treatment and a means of predicting the occurrence of crises. Find out with Doctissimo everything you need to know on this device that has no shortage of breath.

According to Dr. Jean-François Dessanges Cochin Hospital, “all doctors should systematically practice the measurement of peak expiratory flow in all patients as easily taken the voltage.” But this screening exercise is not yet widespread.

Peak flow meters

Who should use this test?
Les debitmetres de pointe. These devices are intended for all adult asthmatics or children from the age of five years. Below this age, the extent of the breath is hard to impose. It is particularly recommended for severe asthma. It allows to evaluate the effectiveness of drug treatment.

Regular measurements to assess the State of the bronchial narrowing. At the request of your doctor, you can save these measures, enter on a book and show them to your doctor, who can better tailor your treatment if necessary.

How does it work?
Flow meters peak (or Peak Flow Meter) allow to compare peak (DEP) of the patient’s expiratory flow to the theoretical DEP and note its evolution. The theoretical DEP standards correspond to the average of the measurements from a large sample of healthy people.

Proportional to the size, the DEP varies with age: lower in children, it is higher among young adults than among the elderly. The man has a peak expiratory flow more important than the woman to equal size and age.

According to the asthma and allergy Association, three examples to illustrate this:
-A teenager measuring 1.45 m has a theoretical DEP of 350 I/min;
-A woman 30 years measuring 1.60 m has a theoretical DEP of 490 I/min;
-A man of 50 years measuring 1.80 m has a theoretical DEP of 620 I/min.
