Sonmol Digital Peak Flow Meter SMPF-1

1. Introduction

The Sonmol Digital Peak Flow Meter SMPF-1 is a portable device designed to measure Peak Expiratory Flow (PEF) and Forced Expiratory Volume in 1 second (FEV1). These measurements are crucial for monitoring lung function, particularly for individuals with respiratory conditions such as asthma and Chronic Obstructive Pulmonary Disease (COPD). This manual provides essential instructions for the safe and effective use, setup, operation, and maintenance of your device.

The device offers high precision and displays results digitally, making it easy to monitor lung performance at home.

2. Deep Breath: Take a deep breath, filling your lungs completely.
3. Exhale Forcefully: Place your lips tightly around the mouthpiece and exhale as hard and fast as you can, ensuring a complete exhalation.
4. View Results: The PEF and FEV1 values will be displayed on the screen automatically.
5. Repeat: For best results, perform three measurements and record the highest value.

5.2. Understanding Readings

• PEF (Peak Expiratory Flow): This indicates the maximum speed of air exhaled from the lungs.
• FEV1 (Forced Expiratory Volume in 1 second): This measures the amount of air exhaled during the first second of a forced breath.

Your physician will provide guidance on interpreting your personal PEF and FEV1 values and what they mean for your lung health. Regularly recording these values can help track changes over time.
