pulse

The measurement of arterial hemoglobin oxygen saturation, pulse, and blood pressure was presented. A review of methods for measuring arterial hemoglobin oxygen saturation based on photoplethysmography was provided. The architecture of the hardware and software platform of a cyber-physical system for the primary processing and transmission of information signals, based on a microcontroller with hardware encryption and a Bluetooth module for transmitting encrypted data to a mobile device and a remote server, was considered.

The electrochemical co-deposition of palladium and gold on the glassy carbon surface from solutions of their salts in dimethylsulfoxide (DMSO) is studied. It is shown that the precipitate in the form of discrete sphere-like particles of 30...140nm, which are uniformly distributed on the substrate, is formed  at concentrations of 0.004M PdCl2 + (0.002...0.004)M HAuCl4 + 0.05M Bu4NClO4, E = -0.3...-1.5V, at pulse electrolysis.
