CPR vs DNR: Understanding Do Not Resuscitate Orders
Short answer
CPR (cardiopulmonary resuscitation) is an emergency procedure to restart a person’s heart and breathing, while a DNR (Do Not Resuscitate) order is a medical directive to withhold CPR if the heart stops. Understanding the difference helps individuals make informed healthcare choices and respect patient wishes during critical moments.
What Is CPR and How Does It Work?
CPR stands for cardiopulmonary resuscitation, a life-saving technique used when someone’s heart stops beating or they stop breathing. It combines chest compressions with rescue breaths to manually maintain blood flow and oxygen to the brain and vital organs until professional medical help arrives. For example, if someone suddenly collapses and is unresponsive, a bystander trained in CPR would call 911, begin chest compressions at a steady rhythm, and provide breaths if trained. This action can help keep the person alive and reduce the chance of brain damage.
Chest compressions work by pressing down on the chest about 2 inches deep at a rate of 100-120 compressions per minute, simulating the heart’s pumping action. Rescue breaths supply oxygen to the lungs. CPR is a temporary measure; emergency responders use advanced tools like defibrillators to further treat the patient.
What Is a DNR Order and What Does It Mean?
A Do Not Resuscitate (DNR) order is a legal document or physician’s instruction that tells medical personnel not to perform CPR or advanced resuscitation if a person’s heart stops or they stop breathing. People usually choose a DNR when they have a serious illness, advanced age, or quality-of-life considerations that make resuscitation unlikely to help or consistent with their wishes.
For instance, if an elderly patient with a terminal illness has a DNR order, healthcare providers will respect that decision and not initiate CPR in an emergency. Instead, care will focus on comfort and symptom management. A DNR does not mean no care will be provided; it only applies to CPR and related emergency measures.
Why Is Knowing the Difference Between CPR and DNR Important?
Understanding CPR versus DNR is crucial because it affects emergency decisions about life-saving treatments. Without clarity, confusion can arise about what actions healthcare providers should take during a crisis. For families and patients, knowing these terms supports having important conversations about end-of-life care preferences before emergencies happen.
For example, a person might want CPR if their heart stops but only under certain conditions, or they may prefer no resuscitation to avoid prolonged suffering. Being informed allows individuals to complete advance directives and communicate clearly with doctors and loved ones, ensuring their wishes are honored.
How Are CPR and DNR Orders Documented and Communicated?
CPR is a medical procedure performed in emergencies, so no prior documentation is needed unless a person has a DNR. A DNR order must be written by a doctor based on a patient’s wishes and medical situation. It is often included in advance directives or medical orders like POLST (Physician Orders for Life-Sustaining Treatment).
To make a DNR effective, patients or their proxies must inform healthcare providers, emergency personnel, and family members. Some states have special DNR bracelets or wallet cards that alert first responders. Without proper documentation, emergency responders will typically perform CPR by default.
What Are Common Misunderstandings About CPR and DNR?
People sometimes confuse DNR with stopping all medical care or think CPR is always successful and risk-free. A DNR only applies to resuscitation efforts, not other treatments like pain relief, antibiotics, or feeding. CPR does not guarantee survival; it may cause broken ribs or other injuries but aims to save life in critical moments.
Another mix-up is between DNR and other related orders, such as DNI (Do Not Intubate), which means no breathing tubes, or full advance directives that cover more than resuscitation. Clarifying these terms prevents unwanted treatments or misunderstandings during emergencies.
What Steps Should You Take to Decide About CPR and DNR?
- Learn about CPR, including how it works and its risks and benefits.
- Reflect on your health status, values, and goals for care.
- Talk with your healthcare provider about whether CPR aligns with your wishes.
- Discuss your preferences with family or healthcare proxy.
- Complete any necessary legal documents, such as advance directives or DNR orders.
- Share your decisions with all involved parties and keep documentation accessible.
Being proactive helps ensure that your choices are respected and reduces stress for loved ones in emergencies.
How Does CPR Relate to Other Emergency Treatments?
CPR is often combined with other interventions like defibrillation, which uses electrical shocks to correct heart rhythm, or advanced airway management in hospitals. DNR orders specifically address CPR and related resuscitation efforts but do not affect other treatments unless specified.
Understanding this relationship clarifies that CPR is one tool among many in emergency care, and a DNR limits only certain actions while allowing others focused on comfort.
Where Can You Learn More About CPR and DNR?
Reliable sources like the American Red Cross provide training and detailed information on CPR techniques and when to use them. Medical websites such as MedlinePlus explain advance directives and how to establish a DNR. Talking to your primary care doctor or a hospital social worker can also guide you through the decision-making process.

Frequently asked questions
Can someone with a DNR order still receive other treatments?
Yes, a DNR order only applies to CPR and resuscitation efforts. Patients can still receive treatments like medications, pain relief, and comfort care unless other directives specify otherwise.
Who can request a DNR order?
Usually, a patient or their legally authorized healthcare proxy can request a DNR order with input from a healthcare provider. The order must be documented and signed by a physician.
What happens if emergency responders don’t know about a DNR?
If a DNR is not clearly documented or communicated, emergency responders will generally perform CPR by default to save the person's life.
Is CPR always successful in restarting the heart?
No, CPR does not guarantee survival. It increases the chance of survival but may not work, especially in cases of severe illness or prolonged cardiac arrest.
Can I change my mind about a DNR order?
Yes, patients can change or revoke their DNR order at any time by informing their healthcare provider and updating any legal documents.
