To pass the certification, focus on a clear understanding of the compression depth, rate, and correct airway management techniques. Maintain compressions at a depth of at least two inches for adults and avoid interruptions to ensure effective circulation.
Remember, rescue breaths should be delivered at a rate of 30:2, and ensuring proper head-tilt chin-lift position is crucial for opening the airway in unconscious individuals. Practice these steps consistently to ensure you’re prepared for real-life emergencies.
Pay special attention to the use of automated external defibrillators (AEDs): Immediate application after a shockable rhythm is detected significantly improves survival chances. The timely and correct use of AEDs can make a life-saving difference in a critical situation.
Review the sequence of actions: Begin with assessing responsiveness, followed by calling for help. This establishes the right order to initiate chest compressions and use the defibrillator effectively. Each step is integral to increasing survival rates in cardiac arrest scenarios.
Here are the corrected lines:
Correctly perform chest compressions at a depth of at least 2 inches (5 cm) for adults. Ensure compressions are consistent at a rate of 100-120 per minute.
Open the airway using the head-tilt, chin-lift method to prevent obstruction during resuscitation efforts.
Check for breathing by observing chest rise and listening for breath sounds for no more than 10 seconds. If no breathing is detected, proceed with CPR.
- For infants, use two fingers for chest compressions, ensuring a depth of about 1.5 inches (4 cm).
- For children, use one hand for compressions at a depth of at least 2 inches (5 cm).
If an AED is available, attach the pads immediately and follow the device’s instructions. Do not delay chest compressions while setting up the AED.
Continue resuscitation efforts until emergency medical services arrive or the individual shows signs of recovery, such as moving or breathing.
- In cases of choking, encourage the person to cough if able. Perform the Heimlich maneuver if the airway is fully obstructed.

Perform high-quality chest compressions with a depth of at least 2 inches, ensuring full recoil after each compression. Maintain a rate of 100 to 120 compressions per minute. Avoid interruptions during compressions and aim for minimal pauses during chest compressions, particularly when performing critical tasks like ventilation.
Ventilation Recommendations
Administer 2 rescue breaths after every 30 compressions. Ensure each breath lasts for about 1 second, making the chest rise visibly. If the chest does not rise, reposition the victim’s head to open the airway and retry. Avoid over-inflating the lungs, as this can lead to gastric distention.
Defibrillation Protocol
When a defibrillator is available, immediately assess the rhythm. If the rhythm is shockable, deliver a single shock and continue CPR, starting with chest compressions. If the rhythm is not shockable, continue CPR and reassess the victim every 2 minutes.
| Task | Action |
|---|---|
| Chest Compressions | Depth: At least 2 inches, Rate: 100-120 compressions per minute |
| Rescue Breaths | 2 breaths after every 30 compressions, Chest rise visible |
| Defibrillation | Deliver shock if rhythm is shockable, 1 shock, resume CPR |
For pediatric patients, adjust compression depth to 1/3 of the chest diameter or about 2 inches for children, and 1.5 inches for infants. For infants, use 2 fingers or 2 thumbs encircling the chest, depending on the size of the child.
Focus on understanding the core concepts related to emergency interventions. Each question will test your ability to identify the best course of action in specific situations. Read each choice thoroughly; eliminate answers that are clearly incorrect. Pay attention to keywords such as “first,” “immediately,” or “most appropriate,” as they help pinpoint the right response. Avoid second-guessing, but double-check if a scenario includes multiple possible solutions, and consider the most critical intervention required at that moment.
When unsure, prioritize steps that align with current protocols. For example, if the question involves cardiopulmonary arrest, choosing immediate chest compressions and airway management will likely be correct. Avoid distractions from less common or outdated practices that may seem plausible but are no longer recommended. Consistency with recognized guidelines ensures accurate decisions.
If a question offers responses that seem equally valid, remember that the exam often favors actions that promote long-term survival, like ensuring circulation and preventing further complications. Referring to systematic protocols such as the chain of survival is a reliable strategy when in doubt.
Mastering CPR techniques involves quick and accurate chest compressions. Aim for 100-120 compressions per minute, ensuring each push reaches at least 2 inches deep for adults. Practice with a manikin to develop consistent depth and rhythm, adjusting the pressure to avoid causing harm. Watch for the chest to rise after each compression to verify effectiveness.
Airway Management
Clear the airway swiftly by using the head-tilt, chin-lift method, ensuring it’s fully open before initiating rescue breaths. In cases where spinal injury is suspected, apply the jaw-thrust maneuver without tilting the head. Keep the airway open throughout the process, especially when transitioning between compressions and breaths.
Rescue Breathing
Deliver two breaths after every 30 compressions. Use a mask or barrier device to provide breaths, avoiding excessive volume. Each breath should last 1 second, just enough to cause the chest to rise. Frequent practice with different types of barriers ensures proficiency under pressure.
Team Dynamics play a major role in real-life scenarios. Efficient communication, including designating roles and maintaining focus, improves outcomes. Practicing with a partner or team will sharpen the ability to alternate roles smoothly during a resuscitation attempt.
Automatic External Defibrillator (AED) Usage requires familiarity with the device’s operation. When deploying an AED, ensure the area is clear and pads are placed on the chest as directed. Follow the machine’s prompts, staying calm and efficient until the shock is delivered. Training with actual devices makes this process second nature.
Skipping the assessment of the scene before approaching the victim can lead to danger. Always verify that the environment is safe before beginning any procedures.
Incorrect chest compression depth and rate is a frequent mistake. Ensure that compressions are at least 2 inches deep and at a rate of 100-120 per minute, avoiding both too shallow and too fast compressions.
Not checking for signs of breathing before starting CPR is another error. Confirm that the person is not breathing or only gasping, rather than assuming based on limited observations.
Failing to provide effective ventilation is a common pitfall. Make sure that the airway is open and that each breath visibly causes the chest to rise.
Misusing AEDs or delaying their use can hinder response time. Always follow the device’s prompts without hesitation, ensuring pads are correctly placed and that no one is touching the victim during shock delivery.
Incorrect hand placement during chest compressions reduces effectiveness. Place hands on the lower half of the breastbone and ensure your body weight is over your hands to generate proper force.
Failing to switch roles regularly during team resuscitation can cause fatigue, decreasing the quality of care. Alternate rescuers every two minutes to maintain high performance.
Not understanding the difference between adult and pediatric procedures can lead to errors. Be sure to adjust technique and equipment according to the patient’s age and size.
Omitting or incorrectly timing the use of rescue breaths in combination with compressions is a frequent mistake. Ensure the correct ratio is followed based on the victim’s condition and whether there’s a barrier between you and the patient.
Not staying calm and confident can lead to hesitation and poor decision-making. Maintain composure and focus on the tasks at hand for optimal results.
For CPR, initiate chest compressions immediately. Ensure the compression depth reaches at least 2 inches for adults and 1.5 inches for children. Maintain a rate of 100-120 compressions per minute.
- Ensure the airway is clear by tilting the head backward and lifting the chin.
- Provide rescue breaths after every 30 compressions. Each breath should last about 1 second, making sure the chest rises visibly.
- For infants, use two fingers for compressions, maintaining the same depth and rate as for children.
- For two-person CPR, one person should handle chest compressions while the other provides rescue breaths.
- Always use an AED as soon as it is available. Follow the prompts provided by the device and do not hesitate to shock if advised.
- After the first set of 30 compressions and 2 breaths, reassess the victim’s response and continue CPR if needed.
