Why do we need to use a peak flow meter for Asthma control.
A peak flow meter diary at home detects the airway narrowing during the Asthma episode, or even before it. The peak flow meter measures the maximum airflow out from your lungs in an forced blow out to make sure your breathing and lungs conditions.Getting to know the peak flow meter normal range, and you always need to find out your own best expiratory peak flow rate/personal best value, then calculate your Asthma zones, the green, yellow,red divisions to make sure if your Asthma symptoms are well controlled.
Suggest a best peak flow meter—Sonmol electronic peak flow meter
For preventing the asthma exacerbation,a reliable peak flow meter with high accuracy is necessary. It reports your breathing conditions ahead of your GP, getting ride of the Asthma attack factors.The revolution it makes are you don’t need your manual calculation for defining your Asthma zones,you even don’t need to pick up and select your best value in each test. It highly reduce the level of difficulty in operation, and friendly to the elder users. It meets all the requirements of modern intelligent devices. By connecting via Bluetooth, you can synchronize all your exhalation records and asthma-related data on your phone. Finally, you can export them to your doctor in the form of an electronic asthma diary. Even in the asthma remote patient monitoring(RPM) management system, Sonmol digital peak flow meter plays an important role to help doctors gain the patient’s breathing condition in real time to maximize the Asthma and COPD acute attack, greatly reducing patient and national health expenses.

No.
Why Fev1 is needed in Asthma and COPD management and diagnose.
For Asthma:
Quo:The Global Initiative for Asthma (GINA) defines asthma by combining variable respiratory symptoms with variable expiratory airflow limitation, expressed as an FEV1/FVC ratio less than 75-80% (7).

For COPD:
Quo:Forced expiratory volume (FEV1) calculates the amount of air that a person can force out of their lungs in 1 second. FEV1 values that are lower than average suggest the presence of COPD. Working out a person’s FEV1 value can help diagnose chronic lung diseases, such as chronic obstructive pulmonary disease (COPD).
Let’s not forget: the GOLD criteria for COPD are based on post-bronchodilator FEV1, published by
