Product Description

Product Description

This device is used to measure Peak Expiratory Flow (PEF) and Forced Expiratory Volume in 1-second (FEV1) in both children and adults. PEF is the fastest speed air can be blown out of the lungs after inhalation. FEV1 measures the volume after exhaling in 1-second. Peak Flow (PEF) and Forced Expiratory Volume in 1-second (FEV1) measurements can tell how well lungs are breathing by monitoring airflow. Doctors can have patients monitor changes in airflow and record the results. The automatic memory stores and provides easy access to the last 240 readings along with the time and date.

5.0 out of 5 stars Replaced My Mechanical Meter, December 13, 2005

By	Gerald F. Govin Jr. "ggovin" (Dayton, OH area USA) - See all my reviews (REAL NAME)

This meter is really nice. It also has optional software and a USB cable available and / or a small printer available from the manufacturer. Amazon's price is competitive.

Without the software the machine takes your peak value from your trials and bases the zone system on this value.

With the software you can set a known peak flow reading (PEF). The meter automatically calculates whether subsequent readings are in the "green", "yellow" or "red" zone. Syncing the device with the software the first time was a bit tricky. You set a patient number for each unit which isstored internally. I eventually got it. Subsequent readings are automatic. Plug it in and it reads and plots both Peak and FEV1 values. The software would be especially convenient for a physician's office as it recognizes each unit and plots tracks the data for multiple devces. Plug a device in, the software recognises the owner and plots the data for them. You assign a patient number to each unit in the software and upload it to the unit. Next time you plug in the unit analysis and plotting is automatic. Easy.

FEV1 is an indicator of obstruction. As I understand it one should be able to expell the vast bulk of the air from one's lungs in one second (FEV1). If one were to know the total amount of air one could expel one would have a measure of vital capacity, VC. The ratio of FEV1 to VC, (FEV1/VC), is a primary indicator of obstruction. Values above 75%, as I understand it, are not so obstructive. Increasingly smaller values indicate increasing obstruction. In short, one can tell lots from this little brief case or purse sized meter.

For about $100 you can get print outs via the optional printer, or if you have your own computer, via the USB link and software. If you have lung trouble that requires monitoring you should get this or a similar device. It works great. If you fall into that category and are modestly computer literate you might well invest in the software too. A manual unit can cost upwards of $20. This is a better value.

5.0 out of 5 stars Review of Spirometry with FEV1, March 13, 2006

By	Jean (Lehigh Valley, PA) - See all my reviews

I've been using a peak flow meter for years and this gives better and more information than any I've used. I also bought the Peak Flow/FEV1 Analyzer Software with USB Cable that works with it and it gives beautiful graphs and excellent information to pass on to my physician. Even without the software, though, the Spritometer has a memory and makes it much easier for me to keep track of my fluctuations.

5.0 out of 5 stars Simple, Easy to Use & Read..., December 13, 2005

By	Marisa Nitsch (Prospect, CT United States) - See all my reviews (REAL NAME)

Amazon Verified Purchase

This is my first Peak Flow Meter. I liked the design and features amazon listed and thought I would try it out. Everything about it holds true, its small enough to toss in a purse or bag, and easy enough to take out and use at any time. It stores your readings which is quite handy. Great device for anyone who wishes to monitor there peak flow rate.

On a seperate note for allergies and peak flows:

For anyone with allergies, this is a nice product as well. I have a latex allegy and a peak flow reader was recommened to me by my allergist. When using it after say, going into a store, I can tell if there were any hidden latex allergins that were not visable. Balloons and such are visable, however perhaps a bunch of ballons were there a few minutes before I set foot in the store. I would not know, but my asthma would kick in. Sometimes its delayed But the peak flow meter would give me a lower reading byt about 15%. So I would know in advance and be able to prepare for a possible reaction, etc. Just an example for anyone out there with similar allergies. Its a great way to check for possible attacks and being small and light, this peak flow is recommended!
