How Does CPR Work? – Exploring the Basics and Benefits of Cardiopulmonary Resuscitation

Introduction

Cardiopulmonary resuscitation (CPR) is a lifesaving technique used to restore breathing and circulation to someone whose heart has stopped beating. It is an essential skill for anyone to have, as it can save the life of someone in cardiac arrest or respiratory distress. The importance of learning CPR cannot be overstated; research has shown that “early bystander CPR can double or even triple a victim’s chance of survival.”

Explaining the Basics of CPR and How it Works

CPR requires three steps: chest compressions, rescue breaths, and defibrillation. Chest compressions are the most important part of CPR, as they help circulate oxygenated blood throughout the body. Compressions should be performed at a rate of 100-120 per minute, with each one pushing down two inches into the chest. Rescue breaths are then given after 30 compressions, which supply oxygen to the victim’s lungs. Defibrillation is only necessary if the victim is unresponsive and not breathing; it involves delivering a shock to the heart to restore its normal rhythm.

When performing CPR, it is important to use proper techniques. The rescuer should stand behind the victim and place their hands on the lower half of the victim’s sternum, with their fingers interlocked. The rescuer should then press down firmly and quickly at least two inches into the chest. After 30 compressions, two rescue breaths should be given. The rescuer should tilt the victim’s head back and pinch their nose shut before sealing their mouth around the victim’s and blowing until their chest rises. This process should be repeated until help arrives or the victim starts breathing on their own.

Evolution of CPR

CPR has evolved significantly since it was first developed in the late 1800s. In 1960, the American Heart Association introduced the first set of guidelines for administering CPR. Since then, there have been numerous changes to the guidelines, including the introduction of hands-only CPR in 2010. Hands-only CPR is a simplified version of CPR that focuses solely on chest compressions, without rescue breaths. It is recommended for use in adults and children over the age of eight.

In addition to hands-only CPR, there are several other variations of CPR, including infant CPR, pet CPR, and water rescue CPR. Each variation is tailored to the specific needs of the victim. For example, infant CPR is designed to be performed on babies younger than one year old, while pet CPR is designed to be performed on animals.

Risks Associated with Performing CPR

While performing CPR can be a life-saving measure, there are some risks associated with it. One of the most common risks is the possibility of causing further damage to the victim. This risk can be minimized by using proper technique and avoiding excessive force when performing chest compressions. Additionally, the rescuer should take safety measures to avoid exposing themselves to any bodily fluids from the victim.

Stories of People Saved by CPR

CPR has been credited with saving countless lives around the world. One such story is that of Chris Dempsey, who was saved by CPR after suffering a sudden cardiac arrest. Chris was on a ski trip with his family when he suddenly collapsed. His wife, Mary, immediately began performing CPR and continued until the paramedics arrived. Thanks to her quick thinking and timely action, Chris survived and made a full recovery.

Another remarkable story is that of Jenna Jordan, who was saved by CPR after drowning in a swimming pool. She had been underwater for nearly 20 minutes when a bystander performed CPR and managed to revive her. Jenna was rushed to the hospital and eventually made a full recovery. Her story highlights the power of CPR and emphasizes the importance of learning this life-saving technique.

Conclusion

CPR is a vital life-saving technique that everyone should learn. It can be used to restore breathing and circulation to someone whose heart has stopped beating, and it can be the difference between life and death. Knowing CPR can give you the confidence to act in an emergency situation and potentially save a life. Everyone should get certified in CPR and take refresher courses regularly to stay up to date on the latest guidelines.
