CPR Medical Abbreviation
What does CPR mean in medical terms?
What is CPR?
CPR (Cardiopulmonary Resuscitation) is an emergency lifesaving procedure performed when someone's heart stops beating or they stop breathing, combining chest compressions with rescue breaths to manually circulate oxygenated blood to the brain and vital organs. It is used in cardiac arrest, drowning, drug overdose, and other emergencies where normal heart and lung function has ceased. CPR is designed to buy critical time until advanced medical care or a defibrillator can restore a normal heart rhythm.
What CPR Stands For and Its Origins
CPR stands for Cardiopulmonary Resuscitation. The word breaks down into three Latin-rooted parts: "cardio" comes from the Greek "kardia," meaning heart; "pulmonary" derives from the Latin "pulmo," meaning lung; and "resuscitation" comes from the Latin "resuscitare," meaning to revive or raise up again. Together, the term literally means "reviving the heart and lungs." The technique as we know it today was formally developed in the late 1950s and early 1960s, when researchers combined closed-chest cardiac compression with mouth-to-mouth ventilation into a single unified protocol. The American Heart Association began promoting CPR training for the general public in 1963, and it has since become one of the most widely taught emergency skills in the world.
How and Where CPR Appears in Clinical Settings
In hospital and clinical documentation, CPR appears in a wide range of contexts. Emergency department records, intensive care unit notes, and code team reports all reference CPR when documenting a resuscitation event. You may see phrases such as "CPR initiated," "CPR in progress," or "CPR withheld per patient directive" in medical charts. Anesthesiology and perioperative records document CPR readiness as part of pre-procedure safety planning. In nursing notes, CPR status is frequently documented alongside a patient's advance directive or Do Not Resuscitate (DNR) order. Paramedic and EMT run reports almost universally include CPR details, specifying the time it was started, who performed it, the number of cycles delivered, and whether return of spontaneous circulation (ROSC) was achieved. Hospital quality and safety teams also track CPR outcomes as a key performance metric under programs like the American Heart Association's Get With The Guidelines initiative.
What CPR Means in Practice for Patients and Families
For patients and their families, understanding CPR status is one of the most consequential conversations that can happen in a healthcare setting. When a care team asks about CPR preferences, they are asking whether the patient wants resuscitation attempted if their heart or breathing stops. This is typically documented through an advance directive, a living will, or a physician order such as a DNR (Do Not Resuscitate) or POLST (Physician Orders for Life-Sustaining Treatment) form. If CPR is performed in a hospital, it involves rhythmic compressions on the chest at a rate of 100 to 120 per minute, often accompanied by bag-mask ventilation or intubation to support breathing. Rib fractures are a common side effect of effective chest compressions, particularly in older patients. Families should ask providers about the realistic likelihood of survival with good neurological outcomes in their loved one's specific situation, as CPR outcomes vary dramatically based on the underlying cause of cardiac arrest and how quickly resuscitation begins.
CPR vs. Related Terms and Common Misunderstandings
CPR is often confused with defibrillation, but they are distinct interventions. CPR maintains circulation manually through physical compression, while defibrillation uses an electrical shock to reset an abnormal heart rhythm such as ventricular fibrillation. An AED (Automated External Defibrillator) delivers that shock and is frequently used alongside CPR, not instead of it. Another common misunderstanding is that CPR always results in survival. In reality, survival rates for out-of-hospital cardiac arrest average around 10 percent nationally, though bystander CPR can double or triple those odds. In-hospital cardiac arrest outcomes are somewhat better because advanced care is immediately available. It is also worth noting that "compression-only CPR," which omits rescue breaths, is now recommended for untrained bystanders by the American Heart Association, as it is easier to perform correctly and still significantly improves survival. Finally, a DNR order does not mean "do not treat" — it specifically means do not attempt CPR; all other treatments, comfort measures, and pain management continue as appropriate.
Questions About CPR
What does CPR mean in medical terms?▾
In medical terms, CPR stands for Cardiopulmonary Resuscitation, an emergency procedure used when a person's heart stops beating or they stop breathing. It involves chest compressions and, when appropriate, rescue breaths to manually circulate blood and oxygen until the heart can be restarted or advanced care arrives. It is considered the foundational response to cardiac arrest in both hospital and out-of-hospital settings.
What does CPR stand for?▾
CPR stands for Cardiopulmonary Resuscitation. 'Cardio' refers to the heart, 'pulmonary' refers to the lungs, and 'resuscitation' means to revive. The term describes the combined act of manually compressing the chest to circulate blood and providing ventilation to support breathing when normal heart and lung function has failed.
When is CPR performed?▾
CPR is performed whenever a person experiences cardiac arrest, meaning their heart has stopped pumping blood effectively. Common triggers include heart attack, drowning, electric shock, severe allergic reaction, drug overdose, and trauma. It may be initiated by bystanders, emergency medical responders, or hospital staff, and should begin as quickly as possible after cardiac arrest is recognized.
What is the difference between CPR and a DNR?▾
CPR (Cardiopulmonary Resuscitation) is the procedure itself, while a DNR (Do Not Resuscitate) is a medical order directing healthcare providers not to perform CPR if a patient's heart or breathing stops. A DNR does not affect any other aspect of care — the patient continues to receive treatments, medications, and comfort measures. Patients and families should discuss DNR preferences with their physician as part of advance care planning.
What does 'CPR status' mean in a hospital chart?▾
When you see 'CPR status' in a hospital chart, it refers to the patient's documented preference or physician order regarding whether CPR should be attempted in the event of cardiac or respiratory arrest. It is typically listed alongside an advance directive or as a POLST order. Patients have the legal and ethical right to accept or decline CPR as part of their overall treatment plan.
Is CPR the same as using a defibrillator?▾
No, CPR and defibrillation are different, though they are often used together. CPR uses physical chest compressions and rescue breaths to manually pump blood and oxygen through the body. A defibrillator delivers an electrical shock to correct a dangerously abnormal heart rhythm such as ventricular fibrillation. In many cardiac arrest situations, both are needed: CPR keeps the patient alive while the defibrillator addresses the underlying electrical problem.
Can bystanders perform CPR without medical training?▾
Yes. The American Heart Association recommends that untrained bystanders perform compression-only CPR, which means pressing hard and fast on the center of the chest at a rate of 100 to 120 compressions per minute without attempting rescue breaths. This hands-only approach is effective and significantly easier for untrained individuals to perform correctly. Calling 911 immediately and starting CPR without delay are the two most important actions a bystander can take.
What are the survival rates for CPR?▾
Survival rates for CPR vary significantly by setting. Out-of-hospital cardiac arrest has an average survival rate of around 10 percent nationally, though this rises to 20 to 40 percent when bystander CPR is started immediately. In-hospital cardiac arrest has higher survival rates, often between 20 and 25 percent, because trained staff and equipment are immediately available. The underlying cause of arrest, time to CPR, and time to defibrillation are the strongest predictors of outcome.
