Adult Peak Flow Meter Free-Breath DL-F03

Description:

The Free-breath DL-F03 adult peak flow meter is a device designed to monitor asthma control in patients. Recommended for children over 12 years old and adults (although younger children may use it depending on individual physiological characteristics). It features a scale ranging from 60-800 L/min and adjustable zone indicators for personalized self-monitoring, determined by a physician based on individual patient data. The device measures peak expiratory flow (PEF) by blowing into the mouthpiece as forcefully and quickly as possible. Early detection of airway narrowing is possible, often before an asthma attack occurs. Primarily used by patients with moderate to severe asthma.

Key Benefits:

• Early Warning System: Identify when urgent medical attention is needed.
• Treatment Effectiveness: Monitor the effectiveness of asthma treatment and adjust the treatment plan accordingly (under doctor's supervision).
• Medication Adjustment Guidance: Determine when to increase or decrease medication dosage (always consult your doctor).
• Trigger Identification: Help pinpoint asthma triggers (e.g., physical exertion).
• Silent Asthma Detection: Even when feeling fine, a peak flow meter can reveal decreased respiratory function, enabling proactive management.

How to Use:

1. Stand upright.
2. Slide the indicator to the bottom of the scale, near the mouthpiece.
3. Hold the peak flow meter upright. Inhale deeply. Hold your breath, place the mouthpiece in your mouth, and seal your lips tightly around it.
4. Keep your head straight and upright.
5. Exhale forcefully and rapidly into the device. Ensure your lips or tongue don't obstruct the mouthpiece. Avoid saliva entering the device, as this can affect accuracy. Stop immediately if you feel dizzy.
6. Your peak expiratory flow (PEF) will be displayed on the scale. Note (write down) the reading and reset the indicator to the bottom.
7. Take three readings and use the highest value as your result.
8. Record your highest morning and evening readings daily on a chart. This chart helps your doctor monitor your condition and adjust your treatment plan if needed.

Interpreting Your Peak Expiratory Flow (PEF) Readings:

Frequently dropping below your usual PEF indicates a potential worsening of your condition. A significant difference between morning and evening readings can also signify deterioration, especially if accompanied by coughing and wheezing upon waking.

Care and Cleaning:

With proper care, the peak flow meter should last for three years. Replace it after this period, as accuracy may decrease. Avoid dropping the device, keep it clean, and protect it from dust. Consult your doctor if you suspect damage or inaccurate readings. Clean the exterior weekly (or more often if needed) using a standard 70-90% isopropyl alcohol (IPA) wipe, paying particular attention to the mouthpiece. You may also wash the peak flow meter externally and internally with warm water and mild liquid detergent. Rinse thoroughly with clean water, shake out excess water, and air dry. Do not disassemble the device; this may affect accuracy.
