Intensive Care Unit Telemedicine: Innovations and Limitations.

Intensive care unit (ICU) telemedicine is an established entity that has the ability to not only improve the effectiveness, efficiency, and safety of critical care, but to also serve as a tool to combat staffing shortages and resource-limited environments. Several areas for future innovation exist within the field, including the use of advanced practice providers, robust inclusion in medical education, and concurrent application of advanced machine learning. The globalization of critical care services will also likely be predominantly delivered by ICU telemedicine. Limitations faced by the field include technical issues, financial concerns, and organizational elements.
