Life Support: Life support refers to the treatments and techniques performed in an emergency in order to support life after the failure of one or more vital organs. Healthcare providers and emergency medical technicians are generally certified to perform basic and advanced life support procedures; however, basic life support is sometimes provided at the scene of an emergency by family members or bystanders before emergency services arrive. In the case of cardiac injuries, cardiopulmonary resuscitation is initiated by bystanders or family members 25% of the time. Basic life support techniques, such as performing CPR on a victim of cardiac arrest, can double or even triple that patient's chance of survival. Other types of basic life support include relief from choking (which can be done by using the Heimlich maneuver), staunching of bleeding by direct compression and elevation above the heart (and if necessary, pressure on arterial pressure points and the use of a manufactured or improvised tourniquet), first aid, and the use of an automated external defibrillator.

Acute Care: Acute care is a branch of secondary health care where a patient receives active but short-term treatment for a severe injury or episode of illness, an urgent medical condition, or during recovery from surgery. In medical terms, care for acute health conditions is the opposite from chronic care, or longer term care. Acute care services are generally delivered by teams of health care professionals from a range of medical and surgical specialties. Acute care may require a stay in a hospital emergency department, ambulatory surgery center, urgent care centre or other short-term stay facility, along with the assistance of diagnostic services, surgery, or follow-up outpatient care in the community. Hospital-based acute inpatient care typically has the goal of discharging patients as soon as they are deemed healthy and stable. Acute care settings include emergency department, intensive care, coronary care, cardiology, neonatal intensive care, and many general areas where the patient could become acutely unwell and require stabilization and transfer to another higher dependency unit for further treatment.
