Abstract
The present invention discloses a method and related apparatus for determining a cardiac parameter from either the arterial blood pressure signal or the photoplethysmographic signal to quantify the degree of amplitude modulation due to respiration (pulse pressure variation) and predict fluid responsiveness. The method involves the application of Lempel-Ziv complexity to a filtered and segmented physiologic signal for direct determination of the fluid status of a patient. Real-time monitoring of fluid status involves the implementation of the disclosed method as part of a bedside monitoring apparatus.
