For someone in need of urgent help, immediate chest compressions are the first step to sustaining life. Begin with ensuring the person is lying on their back in a safe environment. Kneel next to their chest and place your hands, one on top of the other, in the center of the chest. Apply downward pressure with your arms straight, pushing hard and fast at a rate of 100-120 compressions per minute.

Ensure that the depth of each compression is at least two inches, and allow the chest to fully rise between compressions. After every 30 compressions, give two rescue breaths if you are trained to do so. However, if you are unsure about providing breaths, continue with chest compressions without interruption.

When an automated external defibrillator (AED) is available, turn it on and follow the spoken prompts. Attach the electrode pads to the patient’s bare chest. The AED will assess the heart’s rhythm and will guide you whether a shock is needed. If a shock is advised, ensure no one is touching the person and press the shock button when prompted.

After administering a shock, resume chest compressions without delay. Continue this cycle until help arrives or the person shows signs of recovery, such as breathing or movement.

CPR Test – Key Guidelines

Begin chest compressions immediately after confirming that the person is unresponsive and not breathing. Place the heel of one hand on the center of the chest, with the other hand stacked on top. Keep your arms straight and use your body weight to press down hard and fast at a rate of 100-120 compressions per minute. Ensure the chest recoils fully between compressions.

If an AED (Automated External Defibrillator) is available, turn it on and follow the voice prompts. Attach the pads to the person’s bare chest. If shock is advised, make sure no one is touching the victim before delivering it. After the shock, resume chest compressions immediately.

After performing chest compressions for about 2 minutes, check for signs of life or breathing. If there are no signs, continue CPR until emergency medical services arrive or the person shows signs of recovery.

For children, use one hand for chest compressions and reduce the depth if necessary. For infants, use two fingers for compressions and be gentle with pressure. In all cases, airway management is crucial–ensure the airway is clear and that breaths are delivered effectively when performing mouth-to-mouth resuscitation.

When administering rescue breaths, tilt the victim’s head back and lift the chin to open the airway. Pinch the nose shut, cover their mouth with yours, and give two full breaths. Ensure the chest rises with each breath before continuing compressions.

Continuous training and practice are recommended to maintain proficiency in these life-saving techniques. Keep up-to-date with local guidelines and refresher courses regularly to be prepared for emergencies.

Key Steps in Performing CPR on Adults

Begin by assessing the scene for safety. Ensure both you and the victim are out of harm’s way. Check the person’s responsiveness by tapping their shoulder and shouting loudly. If there’s no response, call for help immediately.

Next, check for breathing. Look at the chest for signs of movement, listen for breathing sounds, and feel for air on your cheek. If the person is not breathing, proceed with chest compressions.

  • Position your hands in the center of the chest, just below the nipple line.
  • Place one hand on top of the other and interlock your fingers.
  • Keep your elbows straight and shoulders directly over your hands for maximum pressure.
  • Perform compressions by pressing down at least 2 inches (5 cm) deep, at a rate of 100-120 compressions per minute.
  • Allow the chest to fully rise between compressions.

After 30 compressions, deliver 2 rescue breaths. To do this, tilt the head back slightly to open the airway. Pinch the nose shut and give a breath that lasts about 1 second, ensuring the chest rises. Repeat for a total of 2 breaths.

Continue cycles of 30 chest compressions and 2 rescue breaths until help arrives, or the person begins to breathe on their own. If you are unable to perform rescue breaths, continue chest compressions at the same rate.

If an automated external defibrillator (AED) is available, turn it on and follow the prompts. Apply the pads to the victim’s bare chest, and allow the device to analyze the heart rhythm. If a shock is advised, deliver it as directed by the AED.

How to Properly Assess Victim’s Condition Before Starting CPR

Check for responsiveness. Tap the victim’s shoulder and shout loudly. If no response, proceed with further assessment.

Check for breathing. Look for chest movement and listen for breath sounds. If the victim isn’t breathing or breathing abnormally (gasping), begin resuscitation techniques.

Check for a pulse. Place two fingers on the victim’s neck (carotid artery) or wrist (radial pulse). No pulse means immediate action is required.

If the victim is unresponsive, not breathing, and has no pulse, initiate resuscitation without delay. If pulse is present but the person is not breathing, focus on rescue breathing until help arrives.

If you are unsure about the victim’s pulse or breathing, it’s safer to act. When in doubt, initiate life-saving measures.

Correct Hand Placement for Chest Compressions

Place the heel of one hand on the center of the chest, on the lower half of the breastbone (sternum). Ensure the hand is aligned with the chest and that the fingers are not touching the ribs or the chest wall. Place your other hand on top of the first, interlocking your fingers. Keep your elbows straight and shoulders directly over your hands to apply force vertically down into the chest.

Press down hard and fast, aiming for a compression depth of at least 2 inches (5 cm) for adults. Allow the chest to fully recoil between compressions, but do not lift your hands off the chest. Maintain a rate of 100-120 compressions per minute.

Avoid placing your hands on the upper part of the chest or near the neck, as this reduces the effectiveness of the compressions and may cause injury. The correct hand placement is vital to ensure that compressions are delivered to the heart, not the ribs or the abdomen.

Ideal Compression Depth and Rate in CPR

The depth of chest compressions should be at least 2 inches (5 cm) for adults, with a maximum of 2.4 inches (6 cm). Deeper compressions may cause injury, while shallow compressions are less effective in maintaining blood flow to vital organs.

The rate of compressions should be between 100 and 120 per minute. This ensures adequate blood circulation while preventing fatigue and maintaining the rhythm needed for optimal circulation during resuscitation efforts.

Maintain a full recoil of the chest after each compression to allow the heart to refill with blood, ensuring that every compression contributes to the circulation of oxygenated blood.

Adjust compression techniques for children and infants, reducing the depth and rate according to size and age, but always focus on achieving an effective blood flow to the brain and heart.

Differences in CPR for Children and Infants

For infants under one year old, chest compressions should be performed using two fingers, placed in the center of the chest just below the nipple line. The compression depth should be about 1.5 inches (4 cm), and the rate should be at least 100-120 compressions per minute. For children over one year old, the heel of one hand is used for compressions, and the depth should be about 2 inches (5 cm). The rate remains the same–100-120 compressions per minute.

The rescue breaths for infants are delivered by covering the infant’s mouth and nose with your mouth, ensuring a seal. For children, you use the same technique, but it is possible to give breaths without covering both mouth and nose if the child is older and has a larger mouth. The ratio of chest compressions to rescue breaths is 30:2 for both children and infants when performed by a single rescuer.

Infants require less force when performing chest compressions because their chest walls are softer and more flexible. It’s crucial to use minimal pressure to avoid causing injury. In contrast, children’s chest walls are firmer, so slightly more force is required for compressions.

When checking for signs of circulation in infants, check for the brachial pulse located on the upper arm. For children, check for the carotid pulse in the neck. If you are unsure whether a pulse is present, begin chest compressions immediately.

How to Handle Victims with Obstructed Airway During CPR

Immediately assess the airway. If the victim is unresponsive and not breathing or breathing abnormally, open the airway by tilting the head back and lifting the chin. If the obstruction is visible and within reach, attempt to remove it carefully. Do not perform a blind finger sweep as it may push the object further down the airway.

If the obstruction is not visible or cannot be removed quickly, perform chest compressions. For adults, compress the chest at a depth of at least 2 inches and at a rate of 100-120 compressions per minute. This helps generate pressure in the chest, which may expel the object or restore some airflow.

When performing rescue breaths, do not force air into the lungs if you suspect a blocked airway. Instead, continue chest compressions and reassess the airway after every 30 compressions. If the victim starts to breathe or respond, stop CPR and monitor the situation closely.

If the victim is a child, apply a different approach: use smaller chest compressions, no more than 1.5 inches deep, and ensure you adjust the force of the rescue breaths to prevent further injury to the airway.

When to Stop CPR: Recognizing Signs of Recovery or Death

Stop the chest compressions when you notice any signs of life, such as the return of breathing, purposeful movement, or a pulse. If the person starts coughing, breathing normally, or moving their arms or legs, it may indicate recovery, and you should reassess the situation quickly.

If the individual has no pulse, is not breathing, and shows no response to stimuli, continue until emergency medical responders arrive or exhaustion sets in. In cases where help is unavailable, it’s important to perform until you can no longer safely continue.

In some situations, you may need to stop if the scene becomes unsafe, such as if there is a danger of fire, electrical hazards, or other immediate threats to your safety. If the person’s condition worsens or no signs of life return after a prolonged period, the decision to stop may be necessary. Always rely on professional medical evaluation for final confirmation.

Be cautious if there’s no observable improvement after a considerable period, and you have provided continuous assistance. If the person has been without circulation for too long (usually several minutes), survival chances significantly decrease, even if you are performing correctly.

CPR and AED Use: Integration and Timing

When performing chest compressions, immediately assess if an Automated External Defibrillator (AED) is available. If so, prioritize using it as soon as possible after starting compressions. The speed at which the AED is applied significantly affects the outcome for the individual in need.

The sequence should proceed as follows: begin high-quality chest compressions at a rate of 100-120 per minute and a depth of at least 2 inches. If someone else is present, have them fetch the AED. Once the AED is ready, stop compressions, attach the pads to the chest, and follow the machine’s instructions. If a shock is advised, deliver it promptly, then resume chest compressions immediately afterward. Minimize delays during this process, as each minute without defibrillation reduces survival chances by 10%.

The timing between chest compressions and AED use is critical. Each pause should be as brief as possible to maintain blood circulation to vital organs. The total time for attaching the AED should not exceed 30 seconds, and chest compressions should be resumed as soon as the shock is delivered. If no shock is advised, compressions should resume immediately, without any further delay.

Action Time Consideration
Start chest compressions Immediately upon recognition of cardiac arrest
Get AED As soon as possible, ideally within 1 minute
Attach AED pads Less than 30 seconds
Deliver shock (if advised) As soon as AED instructs
Resume chest compressions Immediately after shock delivery or AED no-shock advice

When an AED is available, the goal is to minimize the time without defibrillation while ensuring that high-quality compressions are maintained throughout the process. Coordination between CPR and AED use can greatly increase the chances of survival.
