As respiratory‑related admissions account for a substantial portion of pediatric ill‑ nesses, there is a pressing need to predict ICU mortality in these cases. This study based on data from 1188 patients, addresses this imperative using machine learning techniques and investigating different class balancing methods for pediatric ICU mortality prediction. This study employs the publicly accessible“Paediatric Intensive Care database”to train, validate, and test a machine learning model for predicting pediatric patient mortality. Features were ranked using three machine learning feature selection techniques, namely Random Forest, Extra Trees, and XGBoost, result‑ ing in the selection of 16 critical features from a total of 105 features. Ten machine learning models and ensemble techniques are used to make accurate mortality predictions. To tackle the inherent class imbalance in the dataset, we applied a unique data partitioning technique to enhance the model’s alignment with the data distribution. The CatBoost machine learning model achieved an area under the curve (AUC) of 72 . 22%, while the stacking ensemble model yielded an AUC of 60 . 59% for mortality prediction. The proposed subdivision technique, on the other hand, provides a significant improvement in performance metrics, with an AUC of 85 . 2% and an accuracy of 89 . 32% . These findings emphasize the potential of machine learning in enhancing pediatric mortality prediction and inform strate‑ gies for improved ICU readiness.  \nKeywords Pediatric mortality, Respiratory diseases, Pediatric ICU, Mortality prediction, Early recognition, Machine learning  \n*Correspondence: Muhammad E.
