Question

define cardiac arrest​

Answer 1

Cardiac arrest is a medical emergency that can be defined as an abrupt and unexpected loss of the functioning of the heart.

• It can result in the death of an individual if prompt care and intervention are not undertaken.
• It mainly occurs when there's some malfunctioning in the electrical system of the diseased heart.
• The patient may lose consciousness and breathing.

Answer 2

• Cardiac arrest occurs when the heart fails to pump properly, resulting in an abrupt decrease of blood flow throughout the body.  
• It is a life-threatening medical emergency that requires urgent cardiopulmonary resuscitation (CPR) until additional treatment is available.
• Cardiac arrest causes a quick loss of consciousness and irregular or absent respiration.  
• While a heart attack or heart failure can induce cardiac arrest, they are not the same, and non-cardiac causes account for 15 to 25% of occurrences.
• Prior to cardiac arrest, some people may suffer chest discomfort, shortness of breath, or nausea.
• Prior to the incident, an increased heart rate and light-headedness may develop.  
• Cardiac arrest usually results in death within minutes if it is not treated with CPR and defibrillation.
