The intensive care unit (ICU) is a complex environment where timely and accurate patient monitoring is crucial for improving outcomes. However, the exponential growth in data complexity and clinical demand imposes substantial barriers to accurate interpretation and timely clinical decision-making. Drawing on recent literature and clinical studies, the chapter highlights the benefits of artificial intelligence (AI) in improving diagnostic accuracy, anticipating deterioration, and reducing cognitive load on clinicians. From predicting mortality and complications to detecting pain, delirium, sepsis, and infections, AI and machine learning algorithms offer new tools for real-time analysis and decision support. Their applications also include optimizing mechanical ventilation, guiding nutritional support, and enhancing hemodynamic monitoring. This chapter also addresses the technical, ethical, and legal challenges associated with AI deployment, emphasizing the need for transparency, data quality, clinician training, and human oversight.
