Tissue oxygenation index
WebOct 27, 2024 · Tissue Saturation Index (TSI) is an absolute measure for the local tissue oxygenation in tissue beneath the sensor. To obtain TSI, a technique called Spatial Resolved Spectroscopy (SRS) is used. TSI can be measured in both brain and muscle. WebNational Center for Biotechnology Information

WebNov 3, 2024 · The Oxygenation Index (OI) may be a more accurate measure of oxygenation dysfunction in ventilated patients as it accounts for mean airway pressure P/FP Ratio adjusts the P/F ratio for the set PEEP requires and arterial blood gas measurement S/F ratio tends to correlates with P/F ratio and is non-invasive
WebJun 30, 2024 · In a study comparing two types of NIRS monitors—NIRO 200, which measures the cerebral tissue oxygenation index (TOI), and INVOS 5100, which monitors rScO2, jugular bulb oxygen saturation (SjvO2) and central venous saturation (ScvO2) were also measured. Thirty one pediatric patients with congenital heart defects were examined. WebAug 30, 2024 · Tissue oxygenation index (TOI) is an indicator of absolute tissue mixed arterial and venous oxygen saturation, and can be calculated using a NIRS technique called spatially resolved spectroscopy (SRS).
