Purpose: This study aimed to evaluate the respiratory rate oxygenation (ROX) index, ROX-heart rate (ROX-HR) index, and saturation of percutaneous oxygen/fraction of inspired oxygen ratio (SF ratio) to predict the success for high-flow nasal cannula (HFNC) treatment applied to patients with hematologic neoplasms.
Methods: A total of 167 patients who were admitted to the hematology intensive care unit were included in this study. Data were collected from electronic nursing records and were analyzed using the ¥ö2 test, independent t-test, Mann-Whitney U test, logistic regression, Receiver Operating Characteristic curve, and Area Under the Curve (AUC).
Results: Eighty-nine (53.3%) patients were successfully weaned from HFNC, while 78 (46.7%) were unsuccessful. Considering specificity and sensitivity, the optimal cut-off points for predicting the success and failure of HFNC oxygen therapy were 4.50 and 14.16 (ROX index), 3.78 and 15.05 (ROX-HR index), and 119.95 and 278.06 (SF ratio), respectively. Time measurement showed that the most significant AUC was recorded before HFNC interruption occurred.
Conclusion: Nurses caring for critically ill patients with hematologic neoplasms should closely observe and periodically check patients¡¯ breathing patterns. It is crucial to continuously monitor three indexes to ensure that ventilation assistance therapy is started at the right time.
