文摘

BackgroundNear-infrared spectroscopy (NIRS)-based cerebral oximetry is a noninvasive technology used to estimate regional cerebral oxygen saturation (rSO₂). Extracranial blood flow is known to substantially affect rSO₂ values measured by most clinically available devices. Several studies have also reported that the Trendelenburg position and upright position have a larger effect on rSO₂ measurements than the supine position. Therefore, we investigated the effect of these two positions (the Trendelenburg position versus the upright position) and extracranial contamination on rSO₂ measurements obtained using two commercially available devices and one prototype device.
