Facelake FSP20 Spirometer

$199.95 199.95

The handheld FSP20 Spirometer checks the health condition of a patient’s lungs using peak flow spirometry. The infrared signal acquisition mode electronically measures items that are related to FVC. This product is suitable for hospital, clinic, personal, and home use.

This spirometry machine uses a turbine measurement system to detect activity related to respiratory health. While exhaling air into the mouthpiece, the turbine blades rotate and send a signal to the light receptor that recognizes the rate of blade rotation. Results display on the sharp 2.8 inch LCD in under five seconds.

The FSP20 does not require professional calibration or specialized training for diagnostic measurements. After holding the power button to turn on the device, the user will see the “Testing” screen that indicates the device is ready to be used. The patient then exhales a full breath of air into the device with a complete seal around the detachable mouthpiece. The measurement test provides a variety of parameter options to aid the user in evaluating the results. 

The lithium-ion battery in the spirometer is rechargeable via USB (optional power adapter not included). Data history is also transferable to a PC with Bluetooth or the included USB cable. Chart visualizations are available on the device to provide additional methods of viewing data results. 

Results can be viewed and managed on a PC using the included software. With this software, measurement results can be shared or printed. Included with the device are a software download key and instructions for downloading the software.


The FSP20 Spirometer’s measurements can aid in the treatment of conditions such as recent cases of MI or shock, cardiac disease, epileptic seizures, uncontrolled hypertensive disease, aortic aneurysm, and hyperthyroidism.

Excellent screening tool

Very easy to use and accurately displays information in both graphs and table.

The Facelake PSP20 is a Great Product and I Have Used it for 8 months

I was diagnosed with some minor lung scarring 8 months ago and I had an official PFT done. I bought this spirometer because it appeared to be very good for the price. The software also was able to be used from my laptop to see trends over time. The readings were almost identical to my hospital PFT readings. The only issue I had was keeping it calibrated. Hospitals calibrate their spirometer daily. I would assume you need to do it at least every month. When I called, they offered to have me send it back and they would recalibrate for free. That was cool but a pain. So, I went to ebay and bought a 3L Syringe for $45. Now I calibrate it weekly and the results are matching what I get at my doctors office. Great product!
