fMRI (functional Magnetic Resonance Imaging)Uses very large magnetic fields to probe the movements of molecules. fMRI takes advantage of differences in the properties of oxygenated and deoxygenated hemoglobin, thus yielding a signal that is related to brain activity (since neural activity uses oxygen)...

A pulse oximeter is a small and light device that looks like a clip. You attach it to a part of your body like the fingers, toes, or earlobes as a non-invasive way of measuring your oxygen saturation level. These devices can quickly detect even the slightest changes of oxygen levels in...
Now, researchers at the University of Missouri are customizing a commercial finger clip device to provide a rapid, noninvasive way for measuring and continually monitoringblood pressure. The device can also simultaneously measure four additional vital signs—heart rate,bloodoxygen saturation, body tempera...
PURPOSE:To make possible the measurement of the respective characteristics including the light transmission and light absorption of blood by using the wavelength light which minimizes the influence of the degree of oxygen satn. and kinetic state of red blood cells which affect the light transmission ...

Measure Heart Rate is an easy-to-use app for testing and recording heart rate. It is suitable for you to test your heart rate in your daily life and work. Feat…
The device operates much like a pulse oximeter, which attaches to the finger to measure oxygen in the blood. In this case, the device measures the rate at which a dye, injected into the potential donor's bloodstream, is cleared by the liver. This novel, non-invasive and rapid test succes...
How does a smart watch measure blood oxygen? Conventional medical pulse oximeter employs the transmissive pulse oximetry method where peripheral parts of the body like ear lobe, fingertips and toes in babies are used. The most popular involves passing light through the finger and measuring light (...
Percutaneous oxygen saturation (SpO2) < 90% using pulse oximetry at the finger during the 6MWT. 4. Presence of other diseases that may severely affect walking ability. 5. Use of experimental drug or participation in a clinical trial within 3 months prior to screening.Patients...
