The authors evaluate CPC pretraining to transfer pediatric ventilation-weaning models between a general and cardiac-focused PICU. They pretrain on one unit’s clinical time series, then fine-tune the full model using labeled data from the other. With 5% target training data, extubation-failure AUROC is 0.736 versus 0.716 for local-only training; window-task AUROC is comparable. Evidence is limited to two PICUs.
