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.
Basic life support (BLS) is a level of medical care which is used for patients with life-threatening condition of cardiac arrest until they can be given full medical care by advanced life support providers (paramedics, nurses, physicians or any trained general personnel).
According to the American Heart Association, out-of-hospital cardiac arrest can affect more than 300,000 people in the United States each year. [5] Three minutes after the onset of cardiac arrest, a lack of blood flow starts to damage the brain, and 10 minutes after, the chances of survival are low. [6]
The ABC system for CPR training was later adopted by the American Heart Association, which promulgated standards for CPR in 1973. As of 2010, the American Heart Association chose to focus CPR on reducing interruptions to compressions, and has changed the order in its guidelines to C irculation, A irway, B reathing (CAB).
The LUCAS can be used both in and out of the hospital setting. [6] [7] The 2015 European Resuscitation Council Guidelines for Resuscitation does not recommend using mechanical chest compression on a routine basis, but are good alternative for situations where it may be difficult or to maintain continuous high-quality compressions, or when it may be too strenuous on the medic to do so. [8]
There are multiple factors during cardiopulmonary resuscitation (CPR) and defibrillation that are associated with success of achieving return of spontaneous circulation. One of the factors in CPR is the chest compression fraction, which is a measure of how much time during cardiac arrest are chest compressions performed.
A medical calculator is a type of medical computer software, whose purpose is to allow easy calculation of various scores and indices, presenting the user with a friendly interface that hides the complexity of the formulas.
The corpulence index yields valid results even for very short and very tall persons, [7] which is a problem with BMI — for example, an ideal body weight for a person 152.4 cm tall (48 kg) will render BMI of 20.7 and CI of 13.6, while for a person 200 cm tall (99 kg), the BMI will be 24.8, very close to the "overweight" threshold of 25, while ...
