KeyFlow - Peak Flow Meter

The KeyFlow Peak Flow Meter is a portable and accurate device designed to measure the maximum expiratory flow (MEF), which is the maximum speed at which air is expelled from the lungs during a forced exhalation. This tool is essential for monitoring and managing respiratory conditions such as asthma, allowing users to assess lung function and detect potential airway obstructions early.

Main Features:

• Ergonomic and portable design: Compact, lightweight, and easy to carry, allowing for use anytime and anywhere with total comfort and discretion.

• Precise and reliable measurements: Provides consistent readings of the maximum expiratory flow, helping detect early changes in lung function and improving respiratory health management.

• Versatile measurement range: Suitable for both adults and children, covering a wide range of flow values, making it ideal for the whole family.

• Easy maintenance: Its design allows for simple cleaning, ensuring durability and consistent performance over time.

Benefits of Use:

• Early detection of asthma attacks: By regularly measuring the expiratory flow, the device helps identify drops in flow before an asthma attack occurs, allowing for early intervention and reducing the risk of complications.

• Treatment monitoring: Helps assess the effectiveness of medications and adjustments in the asthma action plan, based on variations in the maximum expiratory flow, optimizing treatment.

• Identification of triggers: Aids in detecting factors that may affect lung function, such as allergies or exercise, contributing to better disease control and prevention of attacks.

Instructions for Use:

1. Sit upright to ensure accurate results.
2. Slide the red central piece to the bottom of the scale.
3. Place the device's mouthpiece in your mouth, seal it tightly with your lips, and blow as forcefully as you can for at least one second.
4. Repeat the process three times and record the highest value from the measurements.
5. Note the morning and evening readings in the provided table to track your respiratory health.

Cleaning Instructions:

• Avoid disassembling the device to maintain its accuracy.
• Clean the meter externally with IPA (70%) wipes.
• Use disposable mouthpieces when the device is shared among multiple users.
• Replace the device after 30 patients or two weeks of use, whichever comes first, to ensure optimal performance.

Precautions and Warnings:

• Keep the meter out of reach of children to prevent misuse.
• It is crucial to consult your doctor regularly, especially if you notice any changes in the readings.
• If unsure about how to use the device, consult your pharmacist or doctor, or refer to the instructions included with the product.

Technical Specifications:

• Maximum resistance to flow: 0.00384 kPa/L/min at 720 L/min.
• Storage conditions: Temperature between 10-35 ºC and relative humidity between 30-75%.
• Performance standards: ATS/ERS, AS/NZS4237, NHLBI.

Regular use of the KeyFlow Peak Flow Meter provides valuable insights into respiratory health, enabling users to make informed, proactive decisions for better management of their condition.
