As an allergy specialist, I often recommend the peak flow meter to my patients and their families. This small device makes a big difference in asthma care. Peak flow meters help track lung function, provide early warning signs of flare-ups, and guide treatment decisions—all from the comfort of your home.
To see how the peak flow meter works in real life, watch my video demonstration:

Why Use a Peak Flow Meter?
Monitor Your Lungs at Home:
A peak flow meter measures how fast you can blow air out, giving a clear idea of how open your airways are. Regular monitoring helps spot problems early, even before asthma symptoms appear.
Detect Early Flare-Ups
By checking numbers every morning and evening, you can see when your lung function drops, even if you feel well. This helps prevent severe attacks.
Find Your Personal Best
Track your peak flow values twice a day for two weeks when you feel well. The highest value is your "personal best." Compare future readings against this baseline.
Guide Your Asthma Action Plan
Your doctor will use your peak flow numbers to customize a plan for managing symptoms. If values fall below 80% of your personal best, it's time for reliever medication or a doctor's visit, as discussed with your healthcare provider.
Reduce Medication Over Time
Tracking progress allows your doctor to safely adjust medicine when your control improves.
Conclusion
A peak flow meter empowers patients and families to actively manage asthma, reduce unpredictability, and build confidence in day-to-day care. Regular use, paired with your asthma action plan, can make breathing easier and life healthier.

I was diagnosed with Chronic Obstructive Pulmonary Disease (COPD) four years ago. For over two years, I relied on prescription medications and therapies, but unfortunately, the symptoms continued to worsen. My breathing became more laboured, and I experienced increasing fatigue and shortness of breath with even minimal activity.Last year, out of desperation and hope, I decided to try an herbal treatment program from NaturePath Herbal Clinic. Honestly, I was skeptical at first, but within a few months of starting the treatment, I began to notice real changes. My breathing became easier, the tightness in my chest eased, and I felt more energetic and capable in my daily life. Incredibly, I also regained much of my stamina and confidence.It’s been a life-changing experience I feel more like myself again, better than I’ve felt in years. If you or a loved one is struggling with COPD, I truly recommend looking into their natural approach. You can visit their website at www.naturepathherbalclinic.com
