What does CPR mean in PHYSIOLOGY

CPR is an emergency procedure used to restore the circulation of oxygenated blood in a person whose heartbeat and breathing have stopped. It involves chest compressions, rescue breathing, and sometimes the use of an automated external defibrillator (AED).

CPR can be administered by any person with basic knowledge and training. However, it is most effective when performed quickly by someone who has completed a CPR certification course and has practiced their skills.

To correctly perform CPR, begin by checking for signs of consciousness such as coughing or moving. If unresponsive, call 911, then put both hands at the center of the chest and press firmly to compress the heart approximately 2 inches for 30 times while counting aloud. Give two breaths mouth to mouth before going back to compressions. Continue this cycle until help arrives or until there is movement or breathing from the person being resuscitated.

You should never attempt to perform CPR when another individual can do it more effectively–such as someone who is certified or have had practice in administering it. Additionally, if the victim appears to have suffered a severe brain injury or shows signs of life such as breathing or movement, then performing CPR would be unnecessary and potentially harmful. Lastly, if there is no heartbeat detected after checking for one minute using a stethoscope or Automated External Defibrillator (AED), you should not attempt resuscitation as death has already occurred.

Yes - There are two main types of CPR that are recommended by medical professionals – high quality chest compressions for adults and layperson compression-only that includes children over the age of 8 years old. Additionally, there are varying levels of expertise depending on whether an individual has received professional training in performing resuscitation procedures.

No – During adult resuscitation procedures only your body weight is required; however having an automated external defibrillator (AED) on hand can reduce response time during emergencies which improves chances of survival drastically.

Yes– While pushing down on the victims sternum too intensely will not cause any further damage than normal, it can cause discomfort and may lead to decreased effectiveness during resuscitation attempts.

Yes – Mouth-to-mouth ventilation is necessary alongside chest compressions during adult resuscitation events especially if an automated external defibrillator (AED) is not available.
