A Wiggers diagram, named after its developer, Carl Wiggers, is a unique diagram that has been used in teaching cardiac physiology for more than a century. [1] [2] In the Wiggers diagram, the X-axis is used to plot time subdivided into the cardiac phases, while the Y-axis typically contains the following on a single grid: Blood pressure. Aortic ...

The pericardium is a double-walled sac around the heart.The inner and outer (visceral and parietal, respectively) layers are normally lubricated by a small amount of pericardial fluid, but the inflammation of pericardium causes the walls to rub against each other with audible friction.
Using NHTSA guidelines, the National Registry of Emergency Medical Technicians have developed and implemented certification tests for the NHTSA EMT levels, including the EMT level. [11] As of 2006, 39 US states utilize the NREMT EMT exam as part of the state licensing and/or certification procedure. [12]
Cardiopulmonary resuscitation (CPR) is an emergency procedure consisting of chest compressions often combined with artificial ventilation, or mouth-to-mouth in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest.
The cardiac arrest is likely to be of primary cardiac or respiratory cause; The cardiac arrest was witnessed by a bystander or paramedic; Chest compressions were commenced within 10 minutes; The cardiac arrest duration (collapse to arrival at E&TC [ambiguous]) has been < 60 minutes; The patient is aged between 12 and 70 years
