Critical Care Air Transport (CCAT) and Medevac Services provide flying intensive care units (ICUs) using medically equipped aircraft (jets/helicopters) for transferring critically ill/injured patients, bridging gaps where road ambulances fail, ensuring constant medical care (BLS, ALS, CCT), offering rapid transfers (domestic/international), and facilitating access to specialized hospitals, with providers like ICATT Air Ambulance offering 24/7 support in India. These services handle emergencies like accidents, disasters, and critical transfers, featuring advanced life support, certified medical teams (nurses/doctors), and bedside-to-bedside service, reducing transit time significantly.
