Product Description

DL-F03 P1

The peak expiratory flow (PEF). also called peak expiratory flow rate (PEFR) is a person's maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used to monitor a person's ability to breathe out air. It measures the airflow through the bronchi and thus the degree of obstruction in the airways. Peak expiratory flow is typically measured in units of liters per minute (L/min).


Regular use of a peak flow meter can help keep tabs on your asthma by detecting airway narrowing even before you feel any symptoms, giving you time to adjust your medication or take other steps before your symptoms get worse. A peak flow meter can be useful foradults and children as young as 5.


Function

Peak flow readings are higher when patients are well, and lower when the airways are constricted. From changes in recorded values, patients and doctors may determine lung functionality, the severity of asthma symptoms, and treatment. Measurement of PEFR requires training to correctly use a meter and the normal expected value depends on the patient's gender, age, and height. It is classically reduced in obstructive lung disorders such as asthma.
A peak flow meter llows you to measure day-to-day changes in your breathing. Using a peak flow meter can help you:
* Track the control of your asthma over time
* Show how well your treatment is working
* Recognize signs of a flare-up before symptoms appear
* Know what steps to take when you have signs of an asthma flare-up
* Decide when to call your doctor or get emergency care


Measurement

Reading

Description

Green Zone

80 to 100 percent of the usual or

normal peak flow readings are clear.

A peak flow reading in the green zone
indicates that the asthma is under good control.

Yellow Zone

50 to 79 percent of the usual or

normal peak flow readings.

Indicates caution. It may mean respiratory airway

are narrowing and additional medication may be

required.

Red Zone

Less than 50 percent of the usual or

normal peak flow readings.

Indicates a medical emergency. Severe airway narrowing may be occurring and immediate action

needs to be taken. This would usually involve contacting a doctor or hospital.

DL-F03 APP

It can be used together with "Mobile PEF" APP.
Manually input the tested PEF into this APP, it will show result automatically, and create a week or month test report in form of line graph.
