CPR Basics: All About Chest Compressions

CPR is one of the most important things you can learn in a first aid class. It's something that anyone should know how to do, and it's also something that everyone should know they can do. I've heard many stories about people who have performed CPR on someone else and saved their lives but never expected to use it themselves. And even if you don't think you'll ever need to perform CPR yourself, knowing this life-saving technique just might save someone else's life one day. One thing that can make CPR hard is remembering all of its steps correctly and at the right time. So today we're going over everything you need to know about chest compressions: what they are, why they're so important, how often they should be performed—and more!

Chest compressions are the most important part of CPR.

The most important part of CPR is chest compressions. Without them, a patient will definitely die. This is why you should not stop compressing their chest even if you think they are dead or do not respond to any other part of first aid (such as breathing into their mouth).

Keeping a patient's blood circulating is the primary goal of a first responder; without it, death will occur within minutes--and many people die from heart attacks each year because they didn't receive prompt CPR! An automated external defibrillator (AED) may be available at your workplace or in public places like malls and airports; use one if possible instead of doing manual compressions by hand if no human responders are available on site.

You should lay a patient on his/her back and make sure there is space around their chest.

  • Lay the patient on his/her back.
  • Make sure there is space around their chest.
  • Make sure they can breathe and are not in any danger from anyone else who may be in the room with you (for example, if someone is unconscious). If this does not apply to your situation, skip this step.
  • If they are not breathing, you should perform CPR -- this will help keep them alive until help arrives. The best way to do CPR is with two hands on top of one another pressing down hard on the chest. Women should use the heel of their hand instead of fingers when performing chest compressions so that they don't injure themselves while trying to save someone else. You can do CPR on a person's back or stomach; however, some people find it more comfortable if lying face-up during cardiac arrest because then gravity helps pull blood out from under their brain (the most common cause) into other areas where it needs more oxygen. If possible try doing 10 compressions followed by mouth-to-mouth resuscitation before checking again whether they're still breathing normally - this gives enough time for oxygenated blood flow throughout our bodies without wasting precious minutes spent checking every second whether we've succeeded yet!

Using the heel of your hand, place it over one-third of the way down on the breastbone, just below the nipples (in women).

  • Use the heel of your hand, not the palm or fist.
  • Don't press down too hard on their breastbone or ribs (you should be able to feel it but not hurt them).
  • Keep your hand in place during each compression so you don't move around too much and lose count of how many times you've done this already!

Compressions should be about 2 inches deep and at 100 per minute.

Compressions should be about 2 inches deep and at 100 per minute. The rate of compressions is important because it helps the heart keep pumping blood through the body. The depth of compressions is also important because it keeps blood flowing through the heart, lungs, and brain. You can use a timer to keep track of how long you have been doing chest compressions if you are alone with someone who needs CPR or if they are unconscious after an accident or injury.

Compressions make sure that oxygenated blood continues circulating through the body even though there isn't enough oxygen coming in through breathing alone (or even breathing at all). Chest compressions will keep working until someone else takes over so if no one else knows how to do CPR, then YOU should definitely learn!

CPR stands for "Compression-Resuscitation-Pump". That means there are three steps:

  • Compressions
  • Ventilations
  • Repeat

Perform 30 compressions for every 2 breaths.

CPR is not difficult to learn, but it's important that you have the right technique. Here are some things to keep in mind:

  • You should perform 30 compressions for every 2 breaths. If you're unsure if you're doing it right, ask another person to check your technique or find a video online that demonstrates proper CPR techniques.
  • If there is no one else around and you feel comfortable performing CPR on strangers, do 30 compressions before searching for a pulse--but only if they are unconscious! If someone is conscious or alerting others about their situation (for example by yelling for help), stop immediately and call 9-1-1 instead of continuing with chest compressions; otherwise, continue until help arrives! Be sure not to forget this step because it could save someone's life in an emergency situation where seconds count!

Breathe into the nose and mouth, not into their lungs.

  • Breathe into the nose and mouth, not into their lungs.
  • Breathe into their nose and mouth, not into their lungs.
  • You should breathe into their nose and mouth, not into their lungs.

CPR is a very effective way to save lives when performed correctly

CPR is a very effective way to save lives when performed correctly. It should be performed as soon as possible after a person stops breathing before emergency personnel arrives. In fact, the sooner you start CPR, the better your chances are of bringing them back to life.

There are two types of CPR: chest compressions only (also known as compression-only), and chest compressions with rescue breaths (or CPR with rescue breaths). Both types involve pressing down on the center of your victim's chest at least twice per second for about 30 compressions before switching over to giving two breaths every five seconds until help arrives or until he or she starts breathing again on their own


The most important thing to remember is that the more you practice and become familiar with the process, the better off you'll be when it comes time to save someone's life. Even if you've never done CPR before, there's no reason why you couldn't be the person who saves someone else's! If there are any questions about how much pressure should be applied during compressions or how fast they should go at 100 per minute, please contact your local hospital or doctor for further instructions.
