Monitor Peak Expiratory Flow at Home with the Monaghan TRUZONE Peak Flow Meter
The Monaghan TRUZONE® Peak Flow Meter (PFM) is a compact respiratory monitoring device designed to measure Peak Expiratory Flow (PEF)—the fastest speed at which you can force air out of your lungs after taking a deep breath.
Designed for both children and adults, the TRUZONE Peak Flow Meter makes it easy to measure and record peak flow readings at home. Regular monitoring can help identify changes in airway function that can be shared with your physician or healthcare professional as part of your respiratory management plan.
The easy-to-read scale measures peak expiratory flow from approximately 60 to 800 L/min, while the included ColorZone® system can be personalized according to the peak-flow zones established with your healthcare professional.

What Does a Peak Flow Meter Measure?
A peak flow meter measures Peak Expiratory Flow (PEF).
PEF represents how quickly air can be forced out of the lungs after taking a deep breath.
Rather than simply looking at a single measurement in isolation, peak flow readings can be recorded over time and compared with the user's established personal best or treatment zones according to instructions from a physician or licensed healthcare professional.
Personalized ColorZone® System
One of the useful features of the TRUZONE Peak Flow Meter is Monaghan's ColorZone® system.
The ColorZone tape can be positioned according to the user's personal best peak expiratory flow as confirmed by their physician.
This provides a simple visual system for comparing future readings with the zones established as part of the user's treatment plan.
Your physician or healthcare professional should determine how your zones are established and what actions should be taken based on your readings.
One Size for Children & Adults
The TRUZONE PFM is designed as a one-size-fits-all peak flow meter, allowing the same model to be used by children or adults.
This makes it a convenient option for home respiratory monitoring without requiring separate adult and pediatric models.
Individual expected or target peak flow values can differ considerably, so readings should be interpreted using the personal goals and instructions established with a healthcare professional rather than by comparing yourself with another user's reading.
How to Use the TRUZONE Peak Flow Meter
Follow your healthcare professional's instructions and the manufacturer's complete directions for use.
For general operation:
-
Make sure the yellow indicator is reset near the mouthpiece.
-
To reset it, gently shake the TRUZONE Peak Flow Meter vertically until the indicator returns to the reset position.
-
Take as deep a breath as possible.
-
Place the mouthpiece into your mouth and seal your lips around it.
-
Blow out as hard and as fast as possible.
-
Look at the number on the scale beside the yellow indicator.
-
Record the measurement as instructed.
-
Repeat the measurement as many times as directed by your physician or healthcare professional.
Always refer to the manufacturer's instructions for complete directions, cleaning, care, and proper use.
Tracking Peak Flow Over Time
Regular peak flow measurements can help you and your healthcare professional observe changes in your breathing over time.
The TRUZONE system can be used with a daily record to document measurements and compare them with the zones and personal best established with your healthcare professional.
Bring or share your recorded results with your physician or respiratory healthcare professional as instructed.
Important Information
A peak flow meter is a monitoring device and should be used according to your healthcare professional's instructions.
Your expected or personal-best peak flow is individual to you. Do not assume that another person's reading should also be your target.
Contact your physician or licensed healthcare professional when changes in your peak expiratory flow indicate worsening according to the treatment or action plan they have established for you.
Do not make independent changes to prescribed respiratory medications or treatment solely because of a peak flow measurement unless instructed to do so as part of your healthcare provider's treatment plan.
