One approach to defining benefit examines the probability of an intervention leading to a desirable outcome. CPR has been prospectively evaluated in a wide variety of clinical situations. Knowledge of the probability of success with CPR could be used to determine its futility. For instance, CPR has been shown to be have a 0% probability of success in the following clinical circumstances:
- Septic shock
- Acute stroke
- Metastatic cancer
- Severe pneumonia
In other clinical situations, survival from CPR is extremely limited:

In other clinical situations, survival from CPR is extremely limited:
- Hypotension (2% survival)
- Renal failure (3%)
- AIDS (2%)
- Homebound lifestyle (4%)
- Age greater than 70 (4% survival to discharge from hospital)
