ROX index is described as a combination of the ratio of oxygen saturation to the fraction of inspired oxygen [SPO2/FiO2] and respiratory rate. The use of the ROX index could improve the management and treatment of patients with COVID-19 during the current pandemic and recently describe in a variety of observational studies.
The ROX index score can be used to assist in the monitoring of these patients. Prediction tool used to monitor patients on high flow oxygen devices. Aids in the prediction of success or failure of high flow oxygen use. Evaluation of ROX index should be monitored for the first 12 hours.
PURPOSE: Respiratory Rate-Oxygenation Index (ROX index), defined as the ratio of oxygen saturation, fractional percentage of inspired oxygen (SpO2/FiO2) to respiratory rate (RR), has been found to be a predictor of patients who will improve with High-Flow Nasal Oxygen (HFNO) therapy.
ROX index is defined as the ratio of pulse oximetry/fraction of inspired oxygen (SpO 2 /FiO 2) to respiratory rate (RR). Roca et al. ( 8 ), identified patients at high risk of HFNC failure when this index is at 12 hours.
We performed a systematic review and meta-analysis to determine performance of ROX index as a predictor of HFNC failure. Materials and methods: Systematic search was performed in electronic databases (PubMed, Google Scholar, Web of Science and Cochrane Library) for articles published till 15 June 2021 investigating ROX index as a predictor for.
