Definition
What is a myocardial infarction?
Myocardial infarction is also known as a heart attack, occurring when blood flow to the heart is blocked.
What can cause a cardiac arrest?
Causes of cardiac arrest include choking, drug overdose, severe trauma, electrocution, and respiratory shock.
How many cardiac arrests occur annually?
Approximately 560,000 cardiac arrests occur annually in the United States.
What is the first link in the chain?
The first link in the chain of survival is early recognition and prevention.
What does C-A-B stand for in CPR?
C-A-B stands for Circulation, Airway, Breathing.
What is cardiac arrest?
Cardiac arrest is when the heart stops effectively pumping blood through the body.
What is respiratory shock?
Respiratory shock is a condition where the body does not get enough oxygen due to respiratory failure.
What percentage chance of survival is there
The chance of survival for cardiac arrest victims is about 14%.
What does BLS stand for?
BLS stands for Basic Life Support.
What is the purpose of chest compressions?
The purpose of chest compressions is to force blood to circulate throughout the body.
What are arrhythmias?
Arrhythmias are changes in the heartbeat's normal rhythm.
What is severe trauma?
Severe trauma can result from accidents that severely injure the body.
What are the two types of cardiac arrest?
The two types of cardiac arrest are out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA).
What are the steps in the Chain of Survival?
The steps in the Chain of Survival include early recognition, activation of the emergency response system, high-quality CPR, defibrillation, advanced resuscitation, and post-cardiac arrest care.
How much blood is pumped during compressions?
During effective chest compressions, approximately 30% of the blood volume supplied by a normal heartbeat is pumped.
What is biological death?
Biological death is when vital organs can no longer function or be revived.
What does drug overdose lead to?
Drug overdose can lead to cardiac arrest by affecting the heart's electrical system or slowing the heart rate.
What is the difference between OHCA and IHCA?
OHCA occurs outside a hospital setting, while IHCA occurs inside a hospital.
What is high-quality CPR?
High-quality CPR helps maintain blood flow to vital organs until advanced care can be provided.
What is the airway step in CPR?
The airway step involves opening the victim's airway to allow for rescue breaths.
What is clinical death?
Clinical death is when breathing and blood circulation have stopped.
How can electrocution cause cardiac arrest?
Electrocution can disrupt the heart's electrical signals, leading to cardiac arrest.
How does survival chance decrease over time?
The chance of survival decreases by 10% for every minute that passes after the cardiac arrest
What is the role of defibrillation?
The role of defibrillation is to restore a normal heart rhythm in cases of VF or pVT.
What are rescue breaths?
Rescue breaths are given to fill the victim's lungs with air containing oxygen that can be absorbed by the blood.
