Wearable- and Catheter-Based Cardiovascular Signals during Progressive Exsanguination in a Porcine Model of Hemorrhage

This dataset contains cardiovascular data recorded during progressive exsanguination in a porcine model of hemorrhage. Both wearable and catheter-based sensors were used to capture cardiovascular function; the wearable system contained a fusion of ECG, SCG, and PPG sensors while the catheter-based system was comprised of pressure catheters in the aortic arch, femoral artery, and right and left atria via a Swan-Ganz catheter. The signals presented here have been heartbeat-separated, though heartbeat indices (in ms) are also provided for the calculation of heart rate and heart rate variability. Hypovolemia was induced by drawing blood at 7% increments until the animal reached a 20% drop in their mean arterial pressure from baseline.
