RESUMO
The history of the auscultation method of arterial pressure (AP) measurement dates back to more than century ago. Nevertheless, the problem of the accuracy of measurement is still on the agenda. Standards of the accuracy of measurements and data processing are subjects of regular revision and update. The accuracy and reliability of AP monitoring in complex clinical cases are competitive advantages important for manufacturers of medical monitors. A new Triton ElectronicS module for AP measurements based on original technology and results of its testing are considered in this work. An original algorithm of the module operation provides an opportunity for more accurate and convenient monitoring, particularly in case of disordered hemodynamics.
