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.

A computational method for performing and assessing quality of a pulmonary capillary wedge pressure (PCWP) measurement of an individual, comprising:
- acquiring a blood pressure waveform of an individual, wherein the waveform comprises a blood pressure measurement acquired from a pulmonary artery position and a blood pressure measurement acquired from a wedge position, wherein the blood pressure waveform is acquired using a pulmonary artery catheter;
- determining, using a computational processing system, a PCWP measurement from the blood pressure measurement from the wedge position;
- and
- determining, using the computational processing system, a quality assessment for the PCWP measurement using a machine-learning model configured to provide a quality assessment for the PCWP measurement based on the blood pressure measurement acquired from the pulmonary artery position and the blood pressure measurement acquired from the wedge position.
A hemodynamic monitoring system for performing and assessing quality of a pulmonary capillary wedge pressure (PCWP) measurement, comprising:
- a pulmonary artery catheter configured to acquire blood pressure measurement acquired from a pulmonary artery position and a blood pressure measurement acquired from a wedge position, wherein the pulmonary artery catheter comprises a balloon that is inflatable;
- and
- a computational processing system in connection with the pulmonary artery catheter, the computational processing system comprising:
- a processor system;
- a display screen in digital connection with the processor system;
- and
- a memory system comprising one or more applications that can direct the processor system to:
- acquire a blood pressure measurement in a pulmonary artery position;
- inflate the balloon, wherein inflating the balloon allows the catheter to migrate to a wedge position;
- acquire a blood pressure measurement in the wedge position;
- generate a blood pressure waveform from blood pressure measurement acquired from a pulmonary artery position and a blood pressure measurement acquired from a wedge position;
- determine a PCWP measurement from the blood pressure measurement from the wedge position;
- determine a quality assessment for the PCWP measurement using a machine-learning model configured to provide a quality assessment for the PCWP measurement based on the blood pressure measurement acquired from the pulmonary artery position and the blood pressure measurement acquired from the wedge position;
- and
- display one or more of:
- the blood pressure waveform, the PCWP measurement, or the quality assessment for the PCWP measurement on the display screen.
