Immediate Life Support (ILS) course is a multidisciplinary course which provides more diagnostic skills than the BLS course, expands core knowledge, and teaches airway management skills that are important in the initial phase of treating a critically ill patient who needs resuscitation, ECG recognition and rapid safe defibrillation, using an AED or manual defibrillator. It focuses on the essential knowledge and skills appropriate for most healthcare at all stages and levels.
