    Correlation of Oxygen Saturation Index and Oxygenation Index in Hypoxaemic Respiratory Failure among Neonates by B Sunil, E Nithya

    Published 2021-08-01
    “…Introduction: Hypoxaemic Respiratory Failure (HRF) is severe arterial hypoxaemia that is refractory to supplemental oxygen. Oxygen Saturation Index (OSI) can be an alternate method of diagnosing and assessing the severity of HRF as it uses Oxygen Saturation (SpO2 ) in place of Partial Pressure of Oxygen (PaO2 ) and may be utilised with reasonable sensitivity and specificity. …”
