What this trial studies

This observational study aims to validate the Hypotension Prediction Index (HPI), an algorithm that uses machine learning to predict intraoperative hypotension by analyzing arterial pressure waveforms. The study will involve patients undergoing lung resection procedures with one-lung ventilation, focusing on those who require invasive blood pressure monitoring. By continuously assessing various hemodynamic parameters, the HPI seeks to identify early signs of hypotension, potentially improving patient outcomes during surgery.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 years old with ASA physical status II to IV scheduled for lung resection surgeries requiring invasive blood pressure monitoring.

Not a fit: Patients undergoing urgent or emergency procedures, or those with significant cardiac conditions, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better management of blood pressure during lung surgeries, reducing the risk of complications.

How similar studies have performed: While the HPI has been validated in other surgical populations, its application in thoracic surgery with one-lung ventilation is novel.
