$GTCH Big News Alert: SAN DIEGO, Dec. 15, 2020 (GLOBE NEWSWIRE) -- GBT Technologies Inc. (OTC PINK: GTCH) ("GBT”, or the “Company”), announced that its Joint Venture, GBT Tokenize Corp. (“GBT/Tokenize”), started research for advanced oxygen and heart rate systems for its qTerm medical device. The current qTerm oximeter is an optical based sensor system that measures the heart rate and oxygen levels, utilizing an electronic processor and a set of small light-emitting diodes (LEDs). The system uses light sources (LEDs) and a light detector to measure the variation in blood volume in tissues. The variation in the blood volume is used to determine the heart rate and the oxygen levels are measured based on blood cells color. Human blood appears red because of a protein called hemoglobin which contains a red-colored compound for carrying oxygen through the bloodstream.
