Welcome to the AEDCPR Online CPR Certification course. In an emergency situation, seconds count. The goal of this class is to prepare you for an emergency and to help you save a life. It’s important to recognize when an emergency exists, what to do in case of an emergency, when to activate EMS, and what to do until they arrive.
We offer three different types of CPR certifications. Our Healthcare Provider BLS certification class deals with emergency situations for adults, children, and infants. BLS stands for Basic Life Support. It is the most comprehensive CPR class offered. BLS certification is required for medical professionals and caregivers. It is also the most requested course used to satisfy job or school requirements. The CPR/AED course is designed for lay rescuers who do not have to meet state licensure requirements. Our CPR/AED/First Aid certification includes everything in the BLS certification and everything in our First Aid class.
This class covers everything in the Healthcare Provider BLS course and the CPR/AED Course. It also covers the CPR portion of the CPR/AED/First Aid Course. For the complete course, please visit our CPR/AED/First Aid Course page.
After completing the class material, there is a test. This is the same exact test we give in our classroom-based courses. It is a multiple-choice test that contains 25 questions. We strongly advise you to complete all the course material before taking the test. However, you can skip ahead if you like. There is no time limit on the test. Test answers are saved for 30 days. So you can leave the test to review the class material. When you return to the CPR test, you can continue from where you left off or start over from the beginning. You can re-take the test as many times as you like.
The heart is a muscle about the size of your fist. It is located in the center of your chest, behind the lower part of your sternum. The sternum is the bone in the center of your chest where the ribs meet. At the bottom of the sternum is a small bony projection called the xiphoid process.
A heart attack, or myocardial infarction, occurs when blood flow to part of the heart is reduced. This is usually due to a blockage. The lack of oxygenated blood causes the affected part of the heart muscle to die. Coronary Artery Disease often causes blockages due to plaque buildup. Plaque can also break free and cause a blockage in another part of the heart or body. Heart attacks can last for a few minutes or a few hours. Sometimes they can last for several days.
Chest pain may include tightness and pressure. Some victims say it’s like having an elephant sitting on their chest. The pain is steady and will last for at least several minutes. Pain may radiate into the shoulders, arms, upper back, jaw, or teeth. Other symptoms include shortness of breath, difficulty breathing, nausea, vomiting, and sweating.
When the victim’s heart is no longer able to pump blood and provide a pulse, the victim is in cardiac arrest and clinically dead. Cardiac arrest can result from a pulseless rhythm, such as Ventricular Fibrillation or Ventricular Tachycardia. It can also occur when the victim has no heart activity, or Asystole (flatline).
It is essential to act fast! Immediate CPR and Defibrillation within 3-5 minutes will give the victim the best chance of survival.
Clinical Death is when your heart stops pumping blood. Without CPR, Biological Death begins to set in about 4-6 minutes later. Biological Death is when the victim’s brain is damaged and cells in the victim’s heart, brain, and other organs die from a lack of oxygen. The damage caused by Biological Death is irreversible. CPR will provide an oxygen-rich supply of blood to the brain and major organs to prevent the onset of Biological Death. If a victim is resuscitated within the first 4 minutes of cardiac arrest, there is little chance of permanent damage. Between 4 and 6 minutes, Biological Death will set in, and there is a possibility of permanent brain damage. After the onset of Biological Death, that amount of damage will become progressively worse from about 6-11 minutes. After 11 minutes without a supply of oxygen to the brain, the victim will have little chance of survival. These numbers can vary greatly when hypothermia is a factor, especially in the case of a cold water drowning. By providing an oxygen-rich supply of blood to the victim, CPR can postpone the onset of Biological Death until advanced cardiac care can be administered.

CPR or Cardio Pulmonary Resuscitation is provided to victims who are in Cardiac Arrest. Rescue Breathing provides oxygen to the bloodstream of a victim who is unable to breathe adequately. Chest compressions circulate the oxygen-rich blood throughout the victim’s body when the heart is unable to pump blood. The purpose of CPR is to provide an oxygen-rich supply of blood to the major organs, to buy time until Defibrillation and Advanced Care can be administered.

The ABCs of CPR have been modified and are now "CAB". The focus of CPR will now be on circulation. Studies have shown that the sooner compressions are initiated, the better the victim’s chance of survival. The most recent guidelines emphasize giving compressions with minimal breaks for assessments and providing ventilations. Many of the changes do not apply to professional-level courses. Lay-Rescuers will no longer check for breathing or circulation. There have also been changes in the rate and depth of compressions. Our CPR courses include all of the latest updates.
When you observe the victim, the first thing to do is determine if he or she is conscious. If the victim is alert but experiencing possible signs and symptoms of a heart attack, tell the victim to lie down or sit quietly and call 911. To do this, simply shake the victim and ask loudly, “Are you okay?” Look, listen, and feel for signs of normal breathing. Ignore agonal/gasping breaths. If no response and the victim is not breathing, act immediately. If you are alone with no mobile phone, leave the victim to activate the emergency response system and get the AED (if available) before returning to your victim and beginning CPR as quickly as possible. If you are not alone, have someone else activate EMS immediately. Single someone out and instruct him or her to “CALL 911, tell them we have an unconscious victim, and come back. Do you understand?” If they do not respond, be sure to send someone else.
To check for signs of circulation, find the carotid artery and check for a pulse for a full 10 seconds. The carotid can easily be located in the victim's neck. It is about an inch away from the cricoid cartilage in a depression on the side of the neck. Also, look for other signs of circulation, such as movement and color.
You must perform CPR on a hard, flat surface. If a victim is in a bed, you must place a backboard beneath the victim or move the victim to the floor. Remove the victim’s clothing as necessary. Do not attempt to perform CPR through clothing.
If the victim is not breathing and has no pulse, begin CPR. Take your hand from the top of the victim’s head and place the heel of your palm on the lower half of the sternum between the victim's nipples. Now take your other hand, place it over the hand on the victim's chest, and interlock your fingers. Position yourself so that your arms are perpendicular to the victim. Compress the victim’s chest at least 2 inches or 5cm. Compress at a rate of 100-120 per minute. Be sure to push hard and fast. Perform 30 compressions and then give 2 breaths. After 5 cycles of 30 compressions and 2 breaths, reassess the victim starting with a pulse check. If necessary, continue CPR with a compression-to-ventilation ratio of 30:2 and reassess after every 5 cycles.
To give rescue breaths, start by opening the victim’s airway. This is done with the head tilt/chin lift. Place your hand on the victim’s forehead while gently lifting the victim's chin with 2 fingers from your other hand. While you can’t swallow your tongue, when unconscious, it can fall to the back of the mouth and block the victim’s airway. Sometimes the head tilt/chin lift will cause spontaneous respirations.
If you suspect a spinal or cervical injury, do not perform a head tilt/chin lift. Open the airway with the “Jaw Thrust Maneuver”. With the heels of your palms, stabilize the victim’s head. Then place the middle two fingers of each hand under the bony projection of the jaw below each ear. Then thrust the jaw upward without moving the victim’s head. This will effectively open the victim’s airway.
IMPORTANT: Be careful not to breathe with too much force or volume. This will cause abdominal distension. The victim’s abdomen will swell and make it difficult to ventilate.
Starting with a pulse check, you should reassess the victim after every 5 cycles of CPR (about 2 minutes) or after every 10 rescue breaths (about 1 minute). If the victim has no pulse, continue CPR. If the victim has a pulse, check for breathing. If the victim has a pulse but is not breathing, provide 1 minute of rescue breathing (10 breaths), then reassess. If breathing and circulation are present, reassess the victim every 1-2 minutes.
If you do not suspect a spinal or cervical injury, place the victim on their side with their head resting on their shoulder as illustrated below. This will prevent the victim from aspirating vomit and allow you to easily monitor breathing and circulation.
For the purposes of CPR, a victim is considered a child from the age of 1 until the onset of puberty. Children go into cardiac arrest for different reasons than adults. Child victims generally suffer Asphyxial Cardiac Arrest, which is caused by a lack of oxygen (Respiratory Arrest). Ventilations are extremely important in pediatric resuscitation. You must move quickly because a child victim is in need of oxygen.
When you observe the child victim, the first thing to do is determine if they are conscious. To do this, shake the victim and ask loudly, "Are you okay?” Look, listen, and feel for signs of normal breathing. Ignore agonal/gasping breaths. If no response and the victim is not breathing, act immediately. If you witness the collapse and are alone with no mobile phone, leave the victim to activate the emergency response system and get the AED (if available) before returning to your victim and beginning CPR as quickly as possible. If you did not witness the collapse, provide 2 minutes of CPR before leaving the victim to activate 911. If you are not alone, have someone else activate EMS immediately. Single someone out and instruct them to “CALL 911, tell them we have an unconscious victim, and come back. Do you understand?” If they do not respond, be sure to send someone else.
To check for signs of circulation, find the carotid artery and check for a pulse for a full 10 seconds. Locate the carotid in the victim's neck. It is about an inch away from the cricoid cartilage in a depression on the side of the neck. Also, look for other signs of circulation, such as movement and color.
You must perform CPR on a hard, flat surface. If you suspect spinal or cervical injury, support the neck and spine as you move the victim. If the child is in a bed, you must place a backboard beneath them or move them to the floor. Remove the victim’s clothing as necessary. Do not attempt to perform CPR through clothing.
If the child is not breathing and has no pulse, begin CPR. Take your hand from the top of the child’s head and place the heel of your palm on the lower half of the sternum between the nipples. Leave your other hand positioned on the child's forehead. Position yourself so that the arm you are using for compressions is perpendicular to the victim. Compress the child victim’s chest about 2” or 1/3 the depth of the body cavity. Compress at a rate of 100-120 per minute. Be sure to push hard and fast. Perform 30 compressions and then give 2 breaths. After 5 cycles of 30 compressions and 2 breaths, reassess the child, starting with a pulse check. If necessary, continue CPR.
If you suspect a spinal or cervical injury, do not perform a head tilt/chin lift. Open the airway with the “Jaw Thrust Maneuver”. With the heels of your palms, stabilize the victim’s head. Then place the middle two fingers of each hand under the bony projection of the jaw below each ear. Then thrust the jaw upward without moving the victim’s head. This will effectively open the victim’s airway.
If the child victim has a pulse but is not breathing, provide rescue breathing at a rate of 1 breath every 3-5 seconds. The breaths should be sufficient to make the chest rise and be delivered over 1 ½ - 2 seconds. Deliver rescue breaths for about 1 minute, then reassess the victim beginning with a pulse check.
Beginning with a pulse check, you should reassess the victim after every 5 cycles of CPR (about 2 minutes) or after every 1 minute of rescue breathing. If the victim has no pulse, continue CPR. If the victim has a pulse, check for breathing. If the victim has a pulse but is not breathing, provide 1 minute of rescue breathing and reassess. If breathing and circulation are present, reassess the victim every 1-2 minutes.
If you do not suspect a spinal or cervical injury, place the victim on his or her side with their head resting on their shoulder as illustrated below. This will prevent the victim from aspirating any vomit and allow you to easily monitor for breathing and circulation.
For the purposes of CPR, a victim is considered an infant when they are under the age of 1. Infants, like children, go into cardiac arrest for different reasons than adults. Child victims generally suffer Asphyxial Cardiac Arrest, which is caused by a lack of oxygen. Ventilations are extremely important in pediatric resuscitation. You must move quickly because the victim is in need of oxygen.
When you observe the victim, the first thing to do is determine if he or she is conscious. To do this, tap the infant on the shoulders and chest. You may also smack the infant's feet or "flick" them with your fingers. DO NOT SHAKE THE INFANT! Look for signs of normal breathing. Ignore agonal/gasping breaths. If no response and the victim is not breathing, act immediately. If you witness the collapse and are alone with no mobile phone, leave the victim to activate the emergency response system and get the AED (if available) before returning to your victim and beginning CPR as quickly as possible. If you did not witness the collapse, provide 2 minutes of CPR before leaving the victim to activate 911. If you are not alone, have someone else activate EMS immediately. Single someone out and instruct them to “CALL 911, tell them we have an unconscious victim, and come back. Do you understand?” If they do not respond, be sure to send someone else.
To check for signs of circulation, find the brachial artery. This is located in the upper aspect of the arm between the bicep and triceps muscles. You may also use the femoral artery located in the groin area. Also, look for other signs of circulation, such as movement and color.
If the victim is not breathing and has no pulse, begin CPR. Leave one hand on the top of the victim’s head. Place the middle 2 fingers of your other hand on the center of the victim's chest, just below the nipple line. Compress the victim's chest 1.5 inches, about 1/3 the depth of the chest cavity. Compress at a rate of 100-120 per minute. Perform 30 compressions and then give 2 breaths. After 5 cycles of 30 compressions and 2 breaths, reassess the victim starting with a pulse check. If necessary, continue CPR with a compression-to-ventilation ratio of 30:2 and reassess after every 5 cycles.
If you suspect a spinal or cervical injury, do not perform a head tilt/chin lift. Open the airway with the “Jaw Thrust Maneuver”. With the heels of your palms, stabilize the victim’s head. Then place the middle two fingers of each hand under the bony projection of the jaw below each ear. Then thrust the jaw upward without moving the victim’s head. This will effectively open the victim’s airway.
IMPORTANT: If the victim has a pulse but is not breathing, provide rescue breathing at a rate of 1 breath every 6 seconds. The breaths should be sufficient to make the chest rise and be delivered over 1 ½ - 2 seconds. Deliver 10 rescue breaths (about 1 minute). Then reassess the victim, starting this time with a pulse check.
Be careful not to breathe with too much force or volume. This will cause abdominal distension. The victim’s abdomen will swell and make it difficult to ventilate.
Starting with a pulse check, you should reassess the victim after every 5 cycles of CPR (about 2 minutes) or after every 10 rescue breaths (about 1 minute). If the victim has no pulse, continue CPR. If the victim has a pulse, check for breathing. If the victim has a pulse but is not breathing, provide 1 minute of rescue breathing (10 breaths) and reassess. If breathing and circulation are present, reassess the victim every 1-2 minutes.
You may pick up the infant and cradle the victim on his or her side. This will prevent the victim from aspirating any vomit and allow you to easily monitor for breathing and circulation. You may also move the victim.
Quality CPR with good compressions, in conjunction with adequate ventilations, will give your victim the best chance of survival. If you are faced with an emergency situation and do not have proper protective equipment, then it is acceptable to do Compression-Only CPR. Since this is a professional-level course, Compression-Only CPR is recommended for rescuers without protective gear. Survival rates are much higher than with no CPR at all. If you have protective gear, provide full CPR. If you do not have adequate protection, then provide CPR with normal compressions and no ventilations.
Compression-Only CPR is also acceptable for those who are untrained in CPR.
2-Rescuer CPR is more efficient and most likely what you will be using in a hospital situation. There are several benefits of 2-Rescuer CPR. Having 2 rescuers can greatly minimize delays between sets of compressions. Another benefit is that we can tell if the compressions are effective by checking the carotid during compressions. One rescuer will perform ventilations, and the other will perform compressions if necessary. The rescuer giving ventilations will be in charge. He or she will assess the victim and inform the other rescuer whether CPR is required and whether compressions are effective. It is important to communicate during 2-Rescuer CPR. Talk out loud, especially during compressions, so there is no confusion between the rescuers.
Eventually, the rescuer doing compressions will become tired. At that point, they might want to change positions with the other rescuer. It is up to the rescuer performing compressions, Rescuer 2, to request a change.
2-Rescuer CPR for children and infants is usually only done in a hospital setting. For children, the ratio of compressions to ventilations changes to 15:2. All other aspects are exactly the same for children and adults. For infants, 2 rescuer CPR is only done when the victim is intubated or when an infant-sized bag-valve mask is in place. During 2-Rescuer CPR on an infant, compressions are performed by encircling the victim's chest with both hands and compressing with your thumbs.
The AED or Automated External Defibrillator is the single most important advancement in saving victims of sudden cardiac arrest. How and when to use an AED (automated external defibrillator) in conjunction with CPR, to assist a heart attack victim. An AED will only work on victims with a shockable rhythm such as ventricular fibrillation or ventricular tachycardia. When one of these pulseless rhythms is detected, the AED will provide an electrical shock intended to stop all heart activity and allow the heart to resume normal function on its own. It’s important to note that an AED stops the victim's heart. It does not jump-start it. This is why it is important to attach an AED and shock the victim quickly. If the victim is not shocked within the first 5 minutes, then the chance of survival will go down 50%.
The AED should be placed next to the victim’s head, on the same side of the victim as you. If you have completed the ABCs and found no signs of circulation, turn on the AED. If you have already begun CPR at the time the AED arrives, you must STOP CPR IMMEDIATELY. Do not complete your cycle. At this point, the AED takes precedence over CPR. The AED had both visual and voice prompts. As soon as you turn the unit on, it will tell you exactly what to do. First, place the pads on the victim’s bare chest. The pads have an illustration that shows the correct placement. Only use adult AED pads. Do not use child pads on an adult. One pad should be placed on the victim's upper right section of the chest, just below the collarbone. The other pad should be placed on the victim’s side, just below the left armpit. Plug the pad connector into the AED. Then stand clear, the AED will analyze the victim. If shock is advised, the AED will charge and tell you to “press the shock button”. Then it will pause and allow you to perform CPR for 2 minutes. This will provide oxygenated blood to the major organs and sustain the victim. After about 2 minutes, the AED will analyze the victim and provide another shock if needed. The AED will repeat the sequence until EMS arrives.
Using an AED on a child is the same as using it on an adult, with only a few minor differences. Do not turn on the AED until AFTER 5 cycles of CPR to the victim to ensure that the victim has a good supply of oxygenated blood. Use pediatric AED pads if they are available. Pad placement: one pad in the front center of the chest and a second pad on the victim's back, between the shoulder blades.
Choking or Foreign Body Airway Obstruction (FBAO) occurs when food or some other foreign object occludes the airway and prevents air from moving in and out. Generally, the obstruction will become lodged in the opening of the trachea and not inside the trachea.
Foreign Body Airway Obstruction can be broken down into 3 categories. These are complete airway obstruction, partial airway obstruction with poor air exchange, and partial airway obstruction with good air exchange.
The Heimlich Maneuver relieves the obstruction by taking residual air from the victim’s lungs and forcing it out. This is similar to taking an empty soda bottle, placing a cork in the opening, and smashing the sides of the bottle. The force of the air in the bottle will send the cork flying, just like the force of the residual air in a victim’s lungs will send the obstruction soaring.
If you see someone giving the universal sign for choking or you suspect that he or she is choking, do the following. Ask the victim, “Are you choking?” If they acknowledge that they are, then ask them, “Can you speak?” If they cannot speak, the obstruction will need to be relieved. You now need to get permission to help the victim. Tell the victim, “I’ve been trained, I’m going to help you.” If the victim refuses your help, you must back off. If the victim becomes unconscious, then it is implied consent.
Get behind the victim, place one leg between the victim’s legs, and take a wide stance. Wrap your arms around the victim’s abdomen. With one hand, make a fist. Place it just above the victim’s navel with your knuckles facing up. With the other hand, grab your fist and thrust inward and upward. The obstruction should come out within the first few thrusts. Look to see if the obstruction is relieved after every 5 thrusts. Continue these abdominal thrusts until the obstruction is relieved or the victim becomes unconscious.
When a conscious choking victim becomes unconscious, begin CPR immediately. If you’re not alone, send someone to activate EMS. Healthcare Providers should perform 2 minutes of CPR before leaving the victim to activate EMS. The first thing you should do to the victim is the “Tongue Jaw Lift”. With your index finger under the victim’s chin, place your thumb in the victim’s mouth just far enough to grab the jaw and lift it up. This will allow you to see into the victim’s mouth and perhaps see the obstruction. If you see an object, remove it. NEVER DO A BLIND FINGER SWEEP ON A CHILD OR INFANT. Then attempt to open the victim’s airway with the Head Tilt Chin Lift and give a breath. If it doesn’t go in, reposition the head and give another breath. If that does not go in, continue CPR for another 2 minutes.
Infants are not able to tell us that they are choking. When an infant is choking, he or she will kick, thrash, and try to scream. No sound will come out, and they will quickly become cyanotic (bluish discoloration of the skin). We cannot do the Heimlich Maneuver on an infant. Pick up the infant and turn him or her upside down. While resting your arm against your leg as shown in the illustration, hold the victim with their face down. Give 5 back blows between the victim's shoulder blades. Then flip the victim over and give 5 chest thrusts by compressing in the same place we did compressions during CPR. Continue to give 5 back blows followed by 5 chest thrusts until the obstruction is relieved or the victim becomes unconscious.
When a conscious choking victim becomes unconscious, begin CPR immediately. If you’re not alone, send someone to activate EMS. Healthcare Providers should perform 2 minutes of CPR before leaving the victim to activate EMS. During ventilations, open the victim’s mouth to check for foreign objects and obstructions. If you see an object, remove it. Studies have shown that chest compressions are more effective than abdominal thrusts to dislodge a foreign object from an obstructed airway. NEVER DO A BLIND FINGER SWEEP ON A CHILD OR INFANT. Continue CPR until EMS arrives or the victim is responsive.
Real-world emergencies often take place in “less-than-ideal” situations. If you are in a remote location, you may be unable to activate EMS quickly. In the case of an accident, fire, or with multiple victims, you may need to improvise. Priority should be given to the safety of yourself and other rescuers. The important thing is that you do what you can do and be sure to stay within your level of training. We hope that if you are faced with an emergency situation, you can take what you have learned in this course and apply it to the best of your ability.
Activate EMS immediately if someone is experiencing the symptoms of a heart attack or if they are unconscious. Dial 911 or your local EMS department. Do not attempt to drive the victim to the hospital. Do not attempt to drive yourself if you are experiencing any signs or symptoms of a heart attack.
Always protect yourself. Use a barrier device such as a mask with a one-way valve or bag valve mask. Always follow Universal Precautions.
