As our unit and a fire department vehicle are responding to the scene of a patient in cardiac arrest, as we approach an intersection that is highly congested, we should use a different siren tone than the fire department vehicle.
<h3>What is cardiac arrest?</h3>
When the heart unexpectedly and unexpectedly stops pumping, cardiac arrest happens. If this occurs, blood supply to the brain and other important organs is interrupted. Certain arrhythmias that stop the heart from pumping blood result in cardiac arrests.
A medical emergency is cardiac arrest. Outside of a hospital, 90% of persons who experience a cardiac arrest pass die, frequently within minutes. Ventricular fibrillation or ventricular tachycardia, two different forms of arrhythmias, are the main causes of cardiac arrest. Prior cardiac arrest, coronary heart disease, heart valve disease, congenital heart defects, and arrhythmias brought on by defective genes are all significant risk factors. However, persons who were unaware they had a heart condition account for 50% of cardiac arrests.
