Abstract: Systems and methods for computer-assisted analysis of pulmonary capillary wedge pressure (PCWP) measurement acquisition in an individual are provided. Various systems and methods measure a wedge pressure via a pulmonary catheter and determine the quality of the wedge pressure measurement. In some instances, systems and methods utilize a trained computational model to assess PCWP quality. Systems and methods are also directed to determining transitions between a wedge and non-wedge positions, which may utilize fuzzy logic to identify such transitions based on a one or more hemodynamic features.

Abstract: Systems and methods identify respiration signals in a patient, which can be important for monitoring respiratory health. A respiration signal can be extracted based on data within a physiological waveform, such as a blood pressure waveform, a blood flow waveform, an electrocardiogram, or a plethysmogram. The physiological waveform can be filtered to identify and extract the respiration signal, which can be utilized to construct a capnogram waveform. A respiration rate can be calculated from the respiration signal or from the constructed capnogram waveform.

Abstract: A system for monitoring arterial pressure of a patient determines a score that is predictive of responsiveness of the patient to a therapy. Sensed hemodynamic data representative of an arterial pressure waveform of the patient are received by a hemodynamic monitor. Magnitude data and trend data are derived from the hemodynamic data. The score that is predictive of the responsiveness of the patient to the therapy is determined based on the magnitude data and the trend data of the hemodynamic parameter. A representation of the score is output.
