Cardiopulmonary resuscitation (CPR) is a lifesaving technique that aims at keeping blood and oxygen flowing through the body when a person's breathing and heartbeat have stopped unexpectedly. It can be employed in emergencies, such as a cardiac arrest or drowning, where the person is unresponsive and not breathing. Knowing how to perform CPR is essential as it can buy crucial time before the arrival of professional medical help and can significantly increase the likelihood of survival for the affected individual.

The basic procedure for CPR includes giving chest compressions, combined with rescue breaths, in a specific sequence. To perform it effectively, the person providing assistance must push down on the chest at a depth of around 5-6cm and at a rate of 100 to 120 compressions per minute, while giving two rescue breaths after every 30 compressions. This technique helps to circulate blood and oxygen throughout the body, potentially preserving vital organs until further medical treatment is available. It is important to keep practicing these steps, as proper technique and timing can make all the difference in emergency situations.

Understanding CPR

CPR, or cardiopulmonary resuscitation, is a vital first aid procedure that can save lives in emergency situations where a person's heart has stopped beating or they are not breathing effectively. The primary goal of CPR is to maintain a flow of oxygen-rich blood to the brain and other vital organs until advanced medical help arrives.

Performing CPR involves a combination of chest compressions and rescue breaths. To perform chest compressions, place the heel of one hand in the centre of the person's chest, place the other hand on top and press down by 5 to 6cm (2 to 2.5 inches) at a steady rate of 100 to 120 compressions per minute. After every 30 compressions, give 2 rescue breaths. To administer rescue breaths, gently tilt the person's head back and lift their chin to open their airway.

In some cases, a defibrillator may be available to help restart the person's heart. If one is nearby, follow the instructions provided by the defibrillator and continue CPR until medical help arrives or the person starts to breathe normally.

It is essential for everyone to know the basics of CPR in case of an emergency situation. CPR courses may provide practical experience, certification, and helpful resources to ensure you are confident and prepared to perform CPR when needed.

In conclusion, understanding CPR may significantly increase the chances of survival for someone in cardiac arrest or experiencing breathing difficulties. By learning and practising CPR techniques, you can be ready to take life-saving action and make a difference during an emergency.

Steps of CPR Procedure

• Ensure Safety

  Before starting CPR, it's crucial to check your surroundings for any potential dangers. Ensure the area is safe for you and the person in need of assistance.

• Check Response

  Once you've determined the scene is safe, check the person's responsiveness by gently shaking their shoulders and asking them loudly if they are okay.

• Call for Help

  If the person is unresponsive, quickly call for emergency assistance (in the UK, dial 999) and request a defibrillator if available.

• Open the Airway

  To open the airway, tilt the person's head back by placing one hand on their forehead and gently lifting their chin with the other hand. This helps in identifying if the person is not breathing or not breathing normally.

• Check for Breathing

  Look, listen, and feel for signs of breathing for up to 10 seconds. If the person is not breathing or has abnormal breathing (such as gasping), proceed with CPR.

• Perform Chest Compressions

  Begin by placing the heel of your hand in the centre of the person's chest. Place your other hand on top and interlock your fingers. Press down firmly and smoothly at a rate of 2 compressions per second to a depth of 5-6 cm. Continue performing 30 chest compressions.

• Deliver Rescue Breaths

  After completing chest compressions, give two rescue breaths. To do this, pinch the person's nose shut and form a seal around their mouth with yours. Blow into their mouth for about 1 second, allowing the chest to rise. Repeat this process once more before returning to chest compressions.

  Keep alternating between 30 chest compressions and 2 rescue breaths until the emergency services arrive or the person starts to show signs of recovery (such as coughing, talking, or opening their eyes).

CPR for Infants and Children

CPR, also known as cardiopulmonary resuscitation, is a life-saving emergency procedure performed when a person's heart stops beating or they stop breathing. CPR for infants and children differs from adult CPR in technique and compression-to-breath ratio. This section will cover the essential steps for performing CPR on infants (under 1 year) and children (1 year to puberty).

Infant CPR (Under 1 Year)

1. Check for responsiveness: Gently tap the infant’s foot and call their name to see if they respond.

2. Call for help: If the infant remains unresponsive, call for emergency medical help (999 in the UK) immediately.

3. Begin compressions: Position the infant on a firm, flat surface. Place two fingers in the center of the infant's chest, just below the nipple line. Start performing chest compressions by pressing down about 4cm (1.5 inches) deep and at a rate of 100-120 compressions per minute.

4. Open the airway: Tilt the infant's head to a neutral position using the head-tilt/chin-lift technique. Ensure you do not overextend their neck.

5. Give rescue breaths: Cover the infant's mouth and nose with your mouth and give two gentle breaths, ensuring each breath makes the chest rise. Allow the air to exit before giving the next breath.

6. Continue CPR: Repeat the cycle of 30 chest compressions followed by 2 rescue breaths until help arrives or the infant begins to breathe normally. The compression-to-breath ratio in infant CPR is 30:2.

Child CPR (1 Year to Puberty)

1. Check for responsiveness: Call the child's name and tap their shoulder to check for responsiveness.

2. Call for help: If the child remains unresponsive, call for emergency medical help (999 in the UK) immediately.

3. Begin chest compressions: Position the child on a firm, flat surface. Place the heel of one hand in the center of the child's chest and the other hand on top. Press down by 5 to 6cm (2 to 2.5 inches) at a rate of 100-120 compressions per minute.

4. Open the airway: Tilt the child's head gently and lift their chin to open the airway using the head-tilt/chin-lift technique.

5. Give rescue breaths: Pinch the child's nose and cover their mouth with your mouth. Give two breaths, ensuring each breath makes the chest rise, and allow the air to exit before giving the next breath.

6. Continue CPR: Repeat the cycle of 30 chest compressions followed by 2 rescue breaths until help arrives or the child begins to breathe normally. The compression-to-breath ratio in child CPR is 30:2.

It is essential to adapt CPR techniques according to the age and size of the child or infant to maximise the chances of successful resuscitation. For more detailed instructions, consider attending CPR training or refer to NHS guidelines.

Hands-Only CPR

Hands-only CPR is a simplified version of the traditional CPR procedure that focuses on providing chest compressions without rescue breaths. This method is easy to learn and remember, making it more accessible for individuals in emergency situations outside of medical settings.

When someone experiences cardiac arrest, every second counts as their heart stops beating effectively enough to circulate blood to the brain and other vital organs. In such cases, hands-only CPR can be the difference between life and death for the person suffering from cardiac arrest.

To perform hands-only CPR, follow these steps:

1. Call for help: If the person is unconscious and not breathing or not breathing normally, call 999 immediately. If there is someone with you, ask them to find a defibrillator.

2. Start chest compressions: Position yourself next to the person lying on their back. Place the heel of one hand on the centre of their chest, and the palm of your other hand on top. Press down smoothly and firmly at a rate of two compressions per second, or approximately 100 to 120 compressions a minute. You can try pushing to the beat of "Stayin' Alive" by the Bee Gees to maintain the proper rhythm3.

3. Continue compressions: Keep providing chest compressions until either someone else takes over, there are signs of life, or you become exhausted.

Remember that hands-only CPR increases the likelihood of surviving cardiac arrest and is a valuable skill to have in emergency situations 1. By learning this technique, you could potentially save someone's life, possibly even someone you know and love

Automated External Defibrillators (AEDs) and CPR

Automated External Defibrillators (AEDs) are valuable tools that can significantly improve a person's chances of surviving cardiac arrest. When a person experiences cardiac arrest, their heartbeat becomes erratic or stops altogether, leading to a lack of blood flow and oxygen to vital organs. AEDs work by delivering an electric shock that helps to restore a stable heart rhythm. Using an AED in conjunction with Cardiopulmonary Resuscitation (CPR) can dramatically increase the likelihood of a successful outcome in such situations.

In the event of a suspected cardiac arrest, it is crucial to call emergency services for help immediately. While waiting for medical assistance to arrive, initiating CPR is essential to maintain blood flow and provide oxygen to the vital organs. To perform CPR, one should follow these steps:

1. Place the heel of one hand on the centre of the person's chest

2. Place the other hand on top and interlock fingers

3. Keep arms straight and perform chest compressions at a rate of 100 to 120 per minute

4. Push down about 2 inches (5 cm) with each compression

Upon locating an AED, it is important to switch it on and follow the device's audio and/or visual prompts. These prompts will guide the user through the following steps:

• Assess whether the person is in cardiac arrest by checking for the absence of breathing

• Expose the person's chest and attach the AED's adhesive electrode pads

• Ensure nobody is touching the person before delivering the shock

• Resume CPR immediately after the shock, regardless of the person's response

AEDs have been designed to be used by anyone, even individuals without prior training. They are equipped with built-in safeguards to prevent delivering shocks when not necessary, eliminating the risk of harm to the person experiencing cardiac arrest. Continued CPR, combined with the appropriate use of an AED, can make a life-saving difference while waiting for professional medical help to arrive.

Post-CPR Procedure Care

After successful cardiopulmonary resuscitation (CPR), it is vital to provide proper post-resuscitation care for the patient. This care is focused on reducing mortality and morbidity, and requires a closely coordinated multidisciplinary team effort. There are several key steps involved in the care of patients who have achieved return of spontaneous circulation (ROSC) after CPR.

Firstly, the patient's cardiopulmonary status must be assessed and stabilised. This involves close monitoring of vital signs, including blood pressure, heart rate, and oxygen saturation. It may be necessary to provide supplemental oxygen or adjust ventilatory support to ensure adequate oxygenation and ventilation.

Secondly, it is important to manage the potential causes of the cardiac arrest. This may involve initiating treatment for underlying conditions such as coronary angiography for patients without ST-elevation on their 12-lead ECG, or administering appropriate medications to address electrolyte imbalances or ongoing arrhythmias.

Another crucial aspect of post-CPR care is the implementation of targeted temperature management (TTM). This involves maintaining a stable core body temperature within a specific range, typically between 32 and 36 degrees Celsius, for a duration of 24 to 48 hours. TTM has been shown to improve neurological outcomes in patients who have experienced cardiac arrest.

In addition to these interventions, ongoing care for the patient may include the management of potential complications arising from the cardiac arrest. This can involve monitoring for organ dysfunction, such as acute kidney injury or hepatic dysfunction, and addressing any coagulopathy or haematological issues.

Throughout this process, it is essential to provide comprehensive and compassionate care for the patient and their family. This includes clear communication regarding the patient's condition, the interventions being provided, and the expected outcomes. By implementing a coordinated and evidence-based approach to post-resuscitation care, clinicians can work to optimise the recovery and long-term outcomes for patients following cardiac arrest.

CPR Training and Certification

CPR, or cardiopulmonary resuscitation, is a life-saving technique that can be used during instances of cardiac arrest. It is essential for those who wish to learn this vital skill to undertake proper CPR training and obtain certification from reputable organisations.

These courses also often cover the use of automated external defibrillators (AEDs), which can significantly improve the chances of survival during a cardiac arrest.

Participants enrolling in CPR courses should expect to learn the following skills:

• Recognising the signs of a cardiac arrest

• Proper hand placement for chest compressions

• The correct compression rate and depth

• Performing rescue breaths and maintaining an open airway

• AED operation and application

CPR courses may vary in their training methods and duration. Some involve hands-on training sessions, wherein participants practice on manikins to simulate real-life scenarios. Others may offer online courses that provide in-depth knowledge about the CPR procedure through videos and interactive lessons. The Resuscitation Council UK recommends considering a combination of both practical and online training for maximum effectiveness.

After successfully completing a CPR training course, participants receive a certificate, which serves as evidence of their ability to perform life-saving techniques during a medical emergency. Certificates typically require renewal after a specific period to ensure that individuals remain updated with current guidelines and best practices in CPR.

In summary, obtaining proper CPR training and certification is crucial for those who wish to be prepared for cardiac emergencies. By learning the essential skills and techniques, individuals can significantly improve the chances of saving a life during the critical moments of a cardiac arrest.
