"Symona 111" is a diagnostic hardware-software complex. The complex is designed for non-invasive measurements of various physiological parameters of central and peripheral hemodynamics, respiratory function, delivery and consumption of oxygen, metabolism, body temperature, activity of the central and vegetative nervous system. Monitoring is carried out on 123 indicators and their trends using 17 waveforms and nomograms. Used in adults and children (older than 1 year). Complex consists of 9 measuring modules, combined by a computer program: cardioplethysmograph, electrocardiograph, pulsoximeter, non-invasive blood pressure, body temperature (2 channels), electroencephalograph, gas breathing (CO2 + O2), breathing mechanics, metabolograph.
