Spontaneous Breathing Mode: A Risk for Hypoxemia During OLV?

NCT07494006 · Status: ENROLLING_BY_INVITATION · Type: OBSERVATIONAL · Enrollment: 44

Last updated 2026-03-27

No results posted yet for this study

Summary

Patients undergoing thoracic surgery with one-lung ventilation (OLV) are prone to hypoxemia, which is primarily attributable to pulmonary ventilation-perfusion (V/Q) mismatch. This study will preoperatively assess the distribution of pulmonary ventilation under spontaneous breathing and intraoperatively record the lowest peripheral oxygen saturation (SpO₂) during OLV. The aim is to investigate the correlation between these two parameters. The findings are expected to facilitate the prediction of hypoxemia in thoracic surgical patients undergoing OLV.
