What are the 3 phases of cardiac arrest?

What are the 3 phases of cardiac arrest?

Accumulating evidence has suggested that the pathophysiol- ogy of ventricular fibrillation cardiac arrest may consist of 3 time-sensitive phases: electrical, circulatory, and metabolic.

What happens physiologically during cardiac arrest?

Cardiac arrest is the cessation of cardiac mechanical activity resulting in the absence of circulating blood flow. Cardiac arrest stops blood from flowing to vital organs, depriving them of oxygen, and, if left untreated, results in death.

What is the most common cause of cardiopulmonary arrest?

The most common cause of cardiac arrest is an underlying heart problem like coronary artery disease which decreases the amount of oxygenated blood supplying the heart muscle.

What is the most common cause of cardiac arrest in patients with a shockable rhythm?

The most common shockable rhythms associated with cardiac arrest are pulseless ventricular tachycardia and ventricular fibrillation. The most common underlying causes are ischemic heart disease and myocardial infarction.

What phase of cardiac arrest is a patient in immediately after collapsing?

Electrical phase (0–5 minutes)—For the first five minutes of a cardiac arrest with v-fib, the best treatment is immediate defibrillation.

Are there different stages of cardiac arrest?

Evidence has suggested that the pathophysiology of ventricular fibrillation cardiac arrest may consist of 3 time-sensitive phases: electrical, circulatory, and metabolic.

What are 3 causes of cardiac arrest?

The main causes of cardiac arrest related to the heart are:

• a heart attack (caused by coronary heart disease)
• cardiomyopathy and some inherited heart conditions.
• congenital heart disease.
• heart valve disease.
• acute myocarditis (inflammation of the heart muscle).

What are the complications of cardiac arrest?

Most people who experience cardiac arrest do not survive. Among those who do, there is risk of neurologic dysfunction, brain injury, disorders of consciousness, neurocognitive deficits, changes in quality of life, as well as physical and psychological wellbeing.

Who is at risk for cardiac arrest?

It’s rare in people younger than 30. In younger people, the main risk factors are genetics arrhythmias, problems with the structure of the heart or coronary arteries, heart inflammation, and substance use. In older adults, the main risk factors are coronary heart disease and other heart conditions.

How many cardiac arrests can you survive?

Nevertheless, outcomes from cardiac arrest remain poor even when the arrest occurs in the hospital setting, where necessary equipment and adequately trained personnel are readily available. Reported survival rates are 3% to 10%,2,3 although the increasing availability of early defibrillation improves these rates.
