Like other medical professionals, a State-Tested Nursing Assistant (STNA) must achieve and maintain a certification in CPR (cardiopulmonary resuscitation). This is a common first-aid technique used to keep victims of heart failure alive and prevent brain damage until more advanced medical intervention can be given. Our STNA training in Ohio teaches our students how to properly administer CPR and save lives.

CPR has two main goals: to keep the blood flowing and to keep air going in and out of the lungs.

If you find a patient who may potentially be in cardiac arrest or unconscious, the first step is to call 911 for additional help. Once help is on the way, check for a pulse. The STNA classes in Ohio show students all the proper techniques for accurately determining whether or not the patient is breathing or has a pulse.

To begin CPR, the victim must be lying on his or her back on a flat surface. Then you begin with the ABCs of CPR. Developed by the American Heart Association, the ABCs are:

Airway

The mouth and throat need to be clear and unobstructed before any CPR can be given. To clear a blocked airway, you should first place the palm of your hand across the victim’s forehead and push down gently. With the other hand, slowly lift the chin forward and slightly up. Move the chin up until the teeth are almost together, but the mouth is still slightly open.

Tilting the head back and lifting the chin in this manner will move the tongue out of the airway. At this point, you will check again for breathing. If the victim is choking on something, you may see their chest heave as they try to breathe, but you won’t be able to feel or hear air being exhaled. If that happens, you may need to compress the abdomen with forceful thrusts or manually dislodge any object with your fingers.

Once this is done, you have to check for signs of breathing again. Just clearing out the windpipe may sometimes be enough to allow the victim to start breathing on their own. If the victim starts breathing and moving around on their own, you should stop CPR. If this doesn’t happen, you’ll have to help them breathe, by providing mouth-to-mouth resuscitation.

Breathing

Lungs have one main function: remove carbon dioxide and take in oxygen. Normally, the muscles in your chest contract and expand your chest cavity, allowing your lungs to fill with air. Oxygen and carbon dioxide diffuse across the immense surface area of your lungs. Finally, your chest muscles relax, and you exhale.

Rescue breathing uses your lungs to force air into the victim’s lungs at regular intervals. The timing of each breath (about 1.5 to 2 seconds per breath) mimics normal breathing. However, the process is much more like blowing up a balloon than real breathing. You inhale deeply, form a tight seal with your mouth over their mouth, and exhale strongly to push air out of your mouth into theirs. Because you also pinch the victim’s nostrils closed, the air has nowhere to go except down into the lungs, which expand as they fill with air.

Mouth-to-mouth breathing is hard work. Normally, when you inhale, the chest muscles drive the process. In artificial respiration, you’re working against the victim’s relaxed chest muscles. When the chest muscles are relaxed, the chest cavity is small, keeping the lungs in a deflated state. As a rescuer, you have to exhale forcefully into the victim’s mouth for 1 to 2 seconds to overcome this resistance. As the lungs fill with air, the victim’s chest is pushed up at the same time; you can actually see it rise. When you remove your mouth from the victim’s and break the air seal, their chest falls and once again deflates the lungs. As in normal breathing, this results in air being exhaled from the victim’s mouth.

Circulation

After giving two full breaths, if you can’t find a pulse, then you need to provide artificial circulation in addition to breathing.

External chest compressions are used to provide artificial circulation. When you apply rhythmic pressure on the lower half of the victim’s breastbone, you force the heart to pump blood. There is a precise timing you must follow to adequately administer chest compressions. Our 3-hour CPR for STNA training classes in Ohio teach you exactly what to do.

Once you have been trained, you must periodically review the procedure. But this training makes you a valuable asset to your family, friends, and neighborhood for years to come.
