This combined intervention protocol effectively improves the prognosis of critically ill patients and optimizes nursing management models

To investigate the impact of comprehensive rehabilitation nursing combined with refined airway management and nutritional support on the prognosis of critically ill patients and nursing management models, and to develop a new care management protocol. Critically ill patients were divided into a control group (routine nursing) and an intervention group (comprehensive rehabilitation nursing combined with refined airway management and nutritional support). Complications such as pulmonary infection and gastrointestinal bleeding, as well as clinical indicators including oxygen saturation (SpO₂), mechanical ventilation time (MVT), and length of stay (LOS), were compared between the two groups. Logistic regression and XGBoost models were constructed to analyze key influencing factors.
