ClinConnect Summary

This clinical trial is studying how effectively a new technology, called UltraSight AI, can help less experienced medical staff measure an important heart function known as the Left Ventricular Outflow Tract (LVOT) Velocity-Time Integral (VTI). This measurement is crucial for understanding how well blood is flowing in critically ill patients, especially those showing signs of low blood flow, like low blood pressure or changes in consciousness. The goal is to see if these minimally trained operators can obtain reliable measurements when guided by the AI, compared to expert doctors' results.

To participate in this study, patients must be at least 18 years old and currently hospitalized in an Intensive Care Unit (ICU) where they need fluid treatment due to signs of low blood flow. Some examples of these signs include a significant drop in blood pressure, skin changes, or decreased urine output. Participants will undergo a measurement process while being monitored closely. It's important to note that patients with certain heart conditions or those in emergency situations may not be eligible for this trial. Overall, this study aims to improve the accuracy of heart function measurements, which could lead to better care for critically ill patients.
