ABSTRACT
This chapter examines five levels of emergency severity index and time requirements of each level. They are, immediate, emergent, urgent, semiurgent, and nonurgent. It provides examples of man-made disasters and natural disasters. The chapter explains when cardiopulmonary resuscitation should be performed. It also discusses various types of fractures, such as, simple, compound, incomplete, comminuted, spiral, transverse, oblique, buckled, pathologic, stress, and longitudinal. The chapter then discusses external and internal bleeding. It compares hyperthermia with hypothermia. Hypothermia is caused by exposure to excessively cold temperatures, resulting in body temperature dropping below normal. Hyperthermia is caused by exposure to excessive warm temperatures and high humidity, resulting in body temperature rising above normal. Emergency care provides immediate services for patients with sudden and serious illnesses or injuries. An actual medical emergency is defined by prudent layperson standard. An automatic external defibrillator (AED) is a portable machine that monitors heart rhythm and can introduce an electric shock to heart to restore normal rhythm.
