For the American Heart Association’s Basic Life Support (BLS) exam, mastering key concepts is vital. Begin with identifying the correct sequence of actions when providing CPR. For adult patients, start with chest compressions at a depth of at least 2 inches, at a rate of 100-120 compressions per minute. Ensure full chest recoil between compressions. Maintain this rhythm until help arrives or an automated external defibrillator (AED) becomes available.
In cases of a witnessed collapse, provide high-quality chest compressions immediately. If you are trained to do so, use an AED as soon as possible. Attach the pads and follow the device’s prompts. If no shock is advised, resume CPR without hesitation. Remember to perform compressions with minimal interruptions to maximize the chances of survival.
For pediatric BLS, remember that chest compressions are slightly different. For infants, use two fingers for compressions, and for children, use one hand if they are over 1 year old. Compression depth should be about one-third the depth of the chest. These variations are critical for ensuring effective care across different age groups.
Reviewing these core principles, along with staying calm under pressure, is key to success on the exam. Regular practice with scenarios will reinforce your knowledge and ability to act quickly and effectively in real-world situations. Stay confident, stay prepared, and focus on each step as you approach the exam.
Here is the corrected version of the text:
Always assess the scene for safety before approaching a victim. Check for responsiveness by tapping the person and shouting, “Are you OK?” If there is no response, call 911 immediately or direct someone else to do so. If the person is not breathing or is only gasping, begin CPR without delay. Start with chest compressions by pushing hard and fast at the center of the chest, aiming for a depth of at least two inches and a rate of 100 to 120 compressions per minute.
If you are trained in providing rescue breaths, deliver them after every 30 compressions. Open the airway by tilting the victim’s head back and lifting the chin. Pinch the nose shut, give two full breaths, ensuring the chest rises with each breath. Continue alternating between 30 compressions and 2 breaths until help arrives or the victim shows signs of life.
If an automated external defibrillator (AED) is available, use it as soon as possible. Turn it on, follow the voice prompts, and place the pads on the victim’s chest as indicated. The AED will analyze the heart rhythm and advise whether a shock is needed. If it prompts a shock, ensure no one is touching the person and press the shock button. Resume CPR immediately after the shock, continuing until professional help arrives.

For a patient in need of CPR, ensure that you assess the scene for safety before proceeding. If the person is unresponsive and not breathing normally, initiate chest compressions. Perform high-quality chest compressions at a depth of at least 2 inches for adults and at a rate of 100-120 per minute.
Chest Compressions
Use the heel of one hand, placing it on the center of the chest, with your other hand on top. Keep your elbows straight, shoulders directly over your hands, and push hard and fast. If an AED is available, use it as soon as possible, following the prompts.
Rescue Breathing
If you are trained to provide rescue breaths, give 2 breaths after every 30 compressions. Ensure the chest rises with each breath. Continue CPR until help arrives or the person shows signs of life. Avoid interruptions to chest compressions longer than 10 seconds.
Mastering the basics of CPR and the application of life-saving techniques are key elements of the BLS exam. Focus on the following concepts to succeed:
- Chest Compressions: Ensure compressions are deep enough, at least 2 inches, and delivered at a rate of 100 to 120 per minute. Make sure the chest fully recoils between compressions to optimize blood flow.
- Airway Management: Properly open the airway using the head-tilt, chin-lift maneuver. In cases of suspected spinal injury, use the jaw-thrust technique.
- Rescue Breaths: Deliver breaths that create visible chest rise without excessive force. Ensure a good seal around the mouth with the mask during ventilations.
- Defibrillation: If an AED is available, apply it as soon as possible. Follow the prompts, and allow the device to analyze the heart rhythm before administering a shock.
- Compression-to-Ventilation Ratio: For adult patients, perform a 30:2 ratio of chest compressions to rescue breaths. In two-rescuer CPR, this remains the same.
- High-Quality CPR: Consistency is key. Keep the rhythm steady, minimize interruptions, and switch rescuers every two minutes to prevent fatigue.
- Recognizing Cardiac Arrest: Know the signs of sudden cardiac arrest. The patient will be unresponsive, not breathing normally, and without a pulse.
- Infant and Child BLS: For infants, use two fingers for compressions, and for children, use one hand. The compression depth is shallower compared to adults.
Reviewing these core skills will increase your preparedness for the BLS exam. Pay attention to detail during training to refine your techniques.
Familiarize yourself with the BLS guidelines and protocols before attempting the exam. Review the American Heart Association’s current BLS guidelines and focus on the core areas such as CPR techniques, use of AED, and recognizing signs of cardiac arrest. Having a strong grasp of these foundational skills will help you answer questions with confidence.
Understand the Question Format
The exam questions are typically multiple-choice or scenario-based. Read each question carefully and look for keywords that define the action needed. For example, when a question involves CPR, identify whether it asks for adult, child, or infant procedures. This will guide your response based on the specific protocol required.
Focus on Timing and Sequence
Timing and the sequence of actions are vital in BLS. Many questions assess your ability to prioritize steps. For instance, in a situation requiring CPR, the first action is always to check responsiveness, followed by calling for help. Knowing the right sequence ensures your answers reflect the proper protocol.
Practice scenarios and mock exams to build confidence. Time yourself to get a feel for the pace and pressure of the real exam. Familiarity with different question types helps reduce anxiety and improves accuracy when selecting answers.
Stay calm and logical throughout the exam. If you’re unsure about a question, eliminate the obviously incorrect answers and make the best choice based on your knowledge of BLS protocols.
One of the most common mistakes during the BLS exam is failing to perform proper chest compressions. Ensure that your hands are positioned correctly at the center of the chest, with elbows straight, and that you apply enough force to compress the chest by at least 2 inches for adults. Inadequate compressions will not generate sufficient blood flow to vital organs, leading to poor exam performance.
Incorrect Airway Management
Another frequent error is improper airway management. When performing mouth-to-mouth or using a bag-valve mask, always check for adequate chest rise to ensure that air is entering the lungs. Failing to do this can lead to inadequate ventilation, which may cause oxygen deprivation and negatively impact the patient’s chances of survival.
Timing and Sequence of CPR Steps
Misunderstanding the correct order of steps can impact your performance. Always follow the sequence of checking responsiveness, calling for help, and beginning chest compressions before attempting to open the airway. This ensures that circulation is established as soon as possible. Skipping or rearranging these steps can delay treatment and affect exam results.
Practice with a timer to perfect your compressions and ventilations. In the exam, the speed and depth of compressions must meet specific standards, and being too slow or too shallow can result in penalties. Don’t rush or overcompensate for the timing–it’s all about consistency.
Ensure you are familiar with the automated external defibrillator (AED) usage. Not following the correct steps when using an AED, such as failing to clear the patient when delivering a shock, is a critical mistake that can negatively affect your score. Be sure to know how to quickly assess whether a shock is needed and the correct process for administering it.
Now the word “BLS” is not repeated more than 2-3 times per line, while maintaining meaning and correctness.
When administering BLS, focus on delivering high-quality chest compressions, ensuring that each compression is firm and deep enough. Use the correct hand positioning to avoid any misalignment that could affect the effectiveness of your efforts. Keep a steady rhythm, ideally at 100-120 compressions per minute.
Chest Compressions
Chest compressions are the primary component of BLS. Aim for a depth of at least two inches, ensuring that the chest fully recoils between compressions. This helps maintain circulation to vital organs. If you’re not trained in advanced airway techniques, continue with compressions until emergency personnel arrive.
Rescue Breathing
During BLS, rescue breathing should be performed if the person is not breathing. Give two full breaths after every 30 chest compressions. Ensure that the airway is open and seal your mouth tightly over the patient’s mouth. Watch for chest rise to confirm that air is entering the lungs.
Stay focused, avoid distractions, and continually assess the situation. If there is any sign of improvement or change in the person’s condition, reassess and adjust your technique accordingly. Continue until help arrives or the person starts breathing on their own.
