Spontaneous Breathing Mode: A Risk for Hypoxemia During OLV?
Condition(s) studied
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.
Eligibility
Primary outcome measure(s)
- Lowest SpO₂ during OLV — Perioperative
We will record the value of the lowest peripheral oxygen saturation (SpO₂) during intraoperative one-lung ventilation.
