Non-invasive estimation of cardiovascular parameters using ballistocardiography
Abstract:
Ballistocardiography is a non-invasive technique to estimate heart function and relative changes in cardiac output. The goal of this study was to establish the relationship between ballistocardiogram (BCG) parameters and changes in cardiovascular parameters. A group of 20 subjects performed three different exercises on a force plate. In this study, we have characterized the significant differences induced by static and dynamic squats, and controlled respiration exercises on BCG parameters such as IJ-amplitude and RJ-time. The dynamic squat exercise induced the largest changes in IJ-amplitude (107-123% higher) and the RJ-time (21-23% lower). Furthermore, the IJ-amplitude of the BCG signal was found to be positively related to the cardiac output.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
