Advanced Hemodynamics

As an example of a potential application of the HD software, the image shows the immediate blood pressure (reBAP), heart rate, CO and SV response during a stand test recorded with the Finapres^® NOVA.

First plot: reBAP signal. Second plot: CO and SV. Third plot: RR interval (requires ECG+resp configuration)
