What is CPR?
A cardiac arrest occurs when the heart promptly stops pumping blood around your body due to an issue with electrical signals in your heart. During a cardiac arrest, the brain is starved for oxygen, causing the person to collapse and stop breathing. Studies have shown that more than 85% of people who undergo cardiac arrest expire before reaching a hospital or medical care facility and this can be averted if effective CPR (cardiopulmonary resuscitation) is provided by a bystander in the first few minutes of cardiac arrest. Cardiopulmonary resuscitation (CPR) is a vital medical technique which should be given to anyone who is going through a cardiac arrest. CPR is also practical in many cases, including heart attack or near drowning.
Importance of CPR
Cardiac arrest is a serious medical condition that can lead to cessation of life can occur within minutes unless treatment is started.
- CPR can save a life
- CPR can prevent brain death
- CPR makes you confident during medical emergencies
- CPR prevents worsening of any situation
- CPR training makes your more valuable to the community
Types of CPR
1. High-Frequency Chest Compressions
This technique involves imitating hear beats by giving more chest compressions at intervals of time in high frequency. This is a critical technique to help revive one from cardiac arrest.
2. Open-Chest CPR
Open chest CPR is a procedure in which the heart is retrieved through thoracotomy. Compressions are executed using the heel of the hand and opened out fingers against the sternum. This procedure helps to regulate blood flow and coronary perfusion pressure.
3. Interposed Abdominal Compression CPR
Interposed Abdominal Compression is a 3-rescuer technique. This includes the chest and abdominal compressor and the protector providing ventilations. This method incorporates, sternum compressions merged with simultaneous abdominal push. This technique is important to better the coronary perfusion pressure.
How to Give Hands-only CPR?
- Place the person flat on his back on a hard surface. Check if the person is reacting by shaking and communicating to the person.
- Check if they are breathing.
- If they are not responsive and not breathing, start with chest compressions.
- Kneel down on the side of the person in front of their chest.
- Put your hand on the person’s sternum.
- Interlock both your hands on the sternum.
- Keep your elbows straight and get your shoulders over the sternum. Compress the chest up to 5 cm.
- Relax but do not withdraw your hands.
- Allow the chest to return to the normal position before starting with the compressions again.
- Continue to push hard and fast, until medical help is available and/or electric shock machine is accessible.
- Stop only if the patient starts responding or breathes normally.
- Remember to push hard (compress 5 cm with each down stroke) and push fast (100 per minute) at the center of the chest.
In India, only 2 out of 100 people know how to give CPR in an emergency, whereas the death rate due to cardiac arrest is more than 10%. Learning CPR is not only going to empower one to lend a helping hand during such cases, but also help save a life. Every minute counts.
