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.

Worth the money

Fairly complete spirometer assessment. Software could be easier to use.

instructions are

machine works fine but instruction to down to computer are poor. in addition to manipulate software is difficult

Excellent product

Easy to use. Extremely portable. Can not enter the patient's name in the device, so you have to down load each test to a computer before doing the next test
