Illustration of the steps which need to be done during the analysis of a Somnotouch-NIBP exam. A patient wearing the device as illustrated. After raw data import, the QRS/R-wave detection is done by the Domino light software, or in the case of Holter ECG analysis by the Schiller plug-in software. From the ECG, QRS/R-waves are detected and used to calculate the pulse transit time. Finally, BP values are calculated according to specific algorithms. BP values are processed and displayed in the form of a diagnostic report. NIBP indicates non-invasive blood pressure; PTT: pulse transit time; BP: blood pressure; ECG: electrocardiography; Pleth: plethysmography.
