Effect of Cardiorespiratory Changes on Carotid Flow Time During Lung Resection

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study investigates how intraoperative cardiorespiratory alterations—such as anesthesia, patient positioning, one-lung ventilation, open chest, capnothorax, lung recruitment, and volume expansion—impact corrected carotid flow time. The goal is to understand the relationship between carotid flow time and cardiac output in the surgical setting and to evaluate whether carotid flow time can predict fluid responsiveness during one-lung ventilation. Secondary analyses compare hemodynamic and ventilatory variables across sex, ventilation protocol, operative side, recruitment tolerance, and fluid responsiveness. The study enrolls patients undergoing thoracoscopic lung resection and excludes those with carotid pathology or significant carotid anatomy issues that would hinder visualization.
