Full code means that if your heart stops beating or you stop breathing, the medical team will perform every available resuscitation procedure to keep you alive. This includes chest compressions, electric shocks to restart the heart, a breathing tube placed into your airway, and medications delivered through an IV. Full code is the default status for every patient admitted to a hospital unless they’ve had an explicit conversation with their medical provider choosing otherwise.
What Happens During a Full Code
When a patient’s heart stops or they stop breathing, hospital staff call a “Code Blue,” which summons a specialized team to the bedside. This team typically includes a rapid response nurse, an emergency nurse, an intensive care charge nurse, and a supervising physician. Each person has a defined role: one handles chest compressions, another manages defibrillation (delivering electric shocks), another pushes medications through an IV line, and another documents everything in real time.
The interventions follow a standardized sequence laid out by the American Heart Association. Chest compressions begin immediately to manually pump blood through the body. If the heart is in a rhythm that can respond to an electric shock, the team uses a defibrillator. A breathing tube is inserted into the windpipe to deliver oxygen directly to the lungs using a mechanical ventilator. Medications are given to stimulate heart function and stabilize its rhythm. This entire process can last anywhere from a few minutes to well over 30 minutes, depending on how the patient responds.
The Physical Toll of Resuscitation
CPR is physically aggressive by necessity. Effective chest compressions require pushing the breastbone down about two inches at a rate of 100 to 120 times per minute. Rib fractures are largely unavoidable. In one study of 40 patients who received CPR, researchers counted a total of 423 rib fractures, most commonly in the third through sixth ribs on both sides of the chest. Thirty percent of those patients also had fractures of the breastbone itself. About one-third of all fractures were incomplete (meaning the bone cracked but didn’t break all the way through), reflecting the natural elasticity of ribs. These injuries are a known and expected consequence of high-quality CPR, not a sign that something went wrong.
Survival Rates and Recovery
Surviving a full code in a hospital is more common than many people assume, but the odds are still not in your favor. A large analysis covering more than 200,000 patients who had cardiac arrests in hospitals between 2001 and 2024 found that about 34.7% survived to leave the hospital. That rate varied significantly by hospital, ranging from 25% to nearly 45%, depending on factors like staffing, response time, and the patient’s underlying condition.
Survival alone doesn’t tell the whole story. Among survivors of traumatic cardiac arrest, roughly 46% achieved good or moderate neurological recovery, meaning they could return to something close to their prior level of function. About 27% were left with severe disability requiring help with daily activities, and around 11% remained in a vegetative state. These numbers vary depending on the cause of the arrest, how quickly CPR began, and the patient’s age and overall health before the event.
How Full Code Differs From DNR and DNI
Code status exists on a spectrum. Full code sits at one end, meaning everything is done. At the other end are orders that limit specific interventions. The two most common are DNR and DNI, which are often confused with each other but address different medical emergencies.
A DNR (Do Not Resuscitate) order means that if your heart stops, the team will not perform chest compressions, defibrillation, or the other interventions used to restart it. A DNI (Do Not Intubate) order means that if you can’t breathe on your own, the team will not place a breathing tube or connect you to a mechanical ventilator. These are distinct decisions because the situations they address have very different survival profiles. In-hospital cardiac arrest carries a mortality rate above 75%. Mechanical ventilation for breathing failure from causes like pneumonia or heart failure, by contrast, has mortality rates below 40%. A patient could reasonably choose DNR but not DNI, or vice versa, based on their values and medical situation.
Some patients opt for what’s called a “limited code” or “partial code,” where they accept certain interventions but decline others. For example, a patient might agree to chest compressions and defibrillation but refuse intubation. Medical professionals have raised concerns about this approach, noting that picking and choosing individual components from a bundle of treatments designed to work together can lead to combinations that are clinically ineffective or even harmful.
How Code Status Gets Documented
Because full code is the default, no paperwork is required to be full code. You are automatically treated as full code unless you actively choose a different status. Changing your code status, however, does require documentation. In a hospital, this is recorded as a physician order in your medical chart after a conversation between you (or your designated decision-maker) and your medical team.
Outside the hospital, code status is typically documented on a form called a POLST (Physician Orders for Life-Sustaining Treatment) or, in some states like New York, a MOLST (Medical Orders for Life-Sustaining Treatment). These are signed medical orders, not the same as a living will or general advance directive. In New York, for instance, the MOLST form is the only legally authorized document for recording a nonhospital DNR or DNI order. Without one of these forms, emergency responders who arrive at your home are required to attempt full resuscitation.
Why the Conversation Matters
Many patients remain full code simply because no one ever asked them what they wanted. The default status assumes maximum intervention, which is appropriate for someone who hasn’t expressed a preference. But for patients with serious chronic illness, advanced age, or terminal diagnoses, the question of whether full resuscitation aligns with their goals becomes more complex. The physical trauma of CPR, the odds of survival, and the risk of significant neurological impairment after a successful resuscitation are all factors worth weighing.
Code status isn’t permanent. You can change it at any time by talking with your medical team. A patient who was DNR can switch back to full code, and a patient who was full code can choose to limit interventions as their condition or priorities change. The key is having the conversation before an emergency, when there’s time to ask questions and think through what matters most to you.
