Cardiac Arrest_one of the leading causes of death in the world..

Hello steemians..Hope everyone is fine with their works..
First of all I would like to thank Steemit community for giving me this wonderful platform to share my views..and also I would like to thank surpassinggoogle steemgigs for making me a part of their family..
Being a @medico I would like to share few brief points regarding @ cardiac arrest..one of the leading causes of death in the world..if u know how to prevent at least u could save a life..
** What is a cardiac arrest??**
Cardiac arrest is a sudden loss of blood flow resulting from the failure of the heart to effectively pump. Symptoms include loss of consciousness and abnormal or absent breathing.Some individuals may experience chest pain, shortness of breath, or nausea before cardiac arrest.If not treated within minutes, it usually leads to death.
** What are the symptoms of cardiac arrest?
Cardiac arrest is preceded by no warning symptoms in approximately 50 percent of people..For those who do experience symptoms, they will be non-specific, such as new or worsening chest pain, fatigue, blackouts, dizziness, shortness of breath, weakness and vomiting.. When cardiac arrest occurs, the most obvious sign of its occurrence will be the lack of a palpable pulse in the victim. Also, as a result of loss of cerebral perfusion (blood flow to the brain), the victim will rapidly lose consciousness and will stop breathing. The main criterion for diagnosing a cardiac arrest, as opposed to respiratory arrest, which shares many of the same features, is lack of circulation; however, there are a number of ways of determining this. Near-death experiences are reported by 10 to –20 percent of people who survived cardiac arrest..
** What are the causes of cardiac arrest?
Major cause _coronary artery disease,major loss of blood ,very low potassium levels,lack of oxygen,heart failure..
How u could prevent it?
U can prevent cardiac arrest by not smoking ,maintain a physical diet,and a good weight..
Treatment for cardiac arrest?
U could manage cardiac arrest by..CPR_cardiopulmonary resuscitation..
What is a CPR?

Cardiopulmonary resuscitation (CPR) is a key part of the management of cardiac arrest. It is recommended that it be started as soon as possible and interrupted as little as possible. The component of CPR that seems to make the greatest difference in most cases is the chest compressions. Correctly performed bystander CPR has been shown to increase survival; however, it is performed in less than 30% of out of hospital arrests as of 2007. If high-quality CPR has not resulted in return of spontaneous circulation and the person's heart rhythm is in asystole, discontinuing CPR and pronouncing the person's death is reasonable after 20 minutes.Exceptions to this include those with hypothermia or who have drowned..
Longer durations of CPR may be reasonable in those who have cardiac arrest while in hospital. Bystander CPR, by the lay public, before the arrival of EMS also improves outcomes..

Either a bag valve mask or an advanced airway may be used to help with breathing.. High levels of oxygen are generally given during CPR.
Tracheal intubation has not been found to improve survival rates in cardiac arrest and in the prehospital environment may worsen it. When done by EMS 30 compressions followed by two breaths appear better than continuous chest compressions and breaths being given while compressions are ongoing.

For bystanders, CPR which involves only chest compressions results in better outcomes as compared to standard CPR for those who have gone into cardiac arrest due to heart issues.Mechanical chest compressions (as performed by a machine) are no better than chest compressions performed by hand.It is unclear if a few minutes of CPR before defibrillation results in different outcomes than immediate defibrillation. If cardiac arrest occurs after 20 weeks of pregnancy someone should pull or push the uterus to the left during CPR. If a pulse has not returned by four minutes emergency Cesarean section is recommended
