Measuring Heart Function Using Pulmonary Artery Catheter, FloTrac, and Argos in Patients After Heart Surgery

What this Trial Is About

Researchers are evaluating cardiac performance by comparing stroke-volume-index measurements taken by three different methods in patients undergoing and recovering from cardiac surgery. The study focuses on patients after cardiac surgery who have a pulmonary artery catheter and involves monitoring during surgery and in the intensive care unit, including both ventilated and spontaneously breathing patients. The study assesses cardiac performance using three diagnostic tools the pulmonary artery catheter, FloTrac, and the Argos Monitor. These devices measure cardiac output and stroke-volume-index by different mechanisms. Investigations are conducted in the operating theater and intensive care unit to observe measurements under various patient conditions. Participants will be monitored for stroke volume index over a 24-hour period following surgery. The study collects data using these devices without altering patient treatment. Researchers will evaluate and compare the measurements to understand differences among the methods. This observational study does not include treatments or interventions beyond standard care, and participation duration depends on the postoperative monitoring period.
