Be better prepared. Save more lives.
The Perfect Code Blue in Your Pocket.
Code Blue Leader offers instant access to patient-specific guidance and reminders so no critical step is missed or delayed.
In a research trial affiliated with Harvard University, Code Blue Leader significantly improved resuscitations, decreased errors, and demonstrated above-average usability.

Health
Problems
Resuscitations
Cardiac arrest is extremely common and has a very high mortality rate.
The quality and coordination of resuscitations in hospital is suboptimal.
Humans
Human factors lead to a disparity between resuscitation theory and practical application.
Cognitive overload is extremely common in health care providers coordinating resuscitations.
Logistics
The timing of interventions during a resuscitation is critical but difficult to manage.
Optimizing the clinical environment is crucial but often deprioritized.
Quality Improvement
Detailed resuscitation data is difficult to obtain and, therefore, is lacking.
Clean, accurate data is needed for guideline development and progressing medical practice.

Research
Proven in a Randomized Controlled Trial
- Fewer Errors
- 3×
- A 14% increase in correct actions during a code blue and a threefold decrease in the rate of errors.
- Critical Steps Completed
- 100%
- Completion of critical resuscitation steps rose from 85% to 100% with Code Blue Leader.
- Found It Easy to Use
- 94%
- 94% of testers said Code Blue Leader was easy to use and that they would use it frequently.
What Clinicians Say
“This is a great tool for real-life cardiac arrest situations. I am looking forward to using it during future codes!”
Emergency RN
“Straightforward, easy to use, and helpful. Love the integrated timers!”
Radiology MD
“It was easy to settle in to the rhythm of the app, and it was nice to know that the doses, reversible causes, and next steps were in the app in case I forgot something. It's foolproof!”

FAQ
Frequently Asked Questions
Which algorithm does the app follow?
Code Blue Leader follows the Adult Cardiac Arrest algorithm from Advanced Cardiovascular Life Support (ACLS). This algorithm is recommended by the American Heart Association, the Heart and Stroke Foundation of Canada, and other international resuscitation organizations as the best response to an ongoing or imminent cardiac arrest.
I am a nurse, paramedic, or general practitioner. Is this app for me?
Built by emergency medicine physicians for all medical professionals, Code Blue Leader is designed for any ACLS-certified individual involved in cardiac arrest response. That includes hospital staff, paramedics, military medics, family doctors, and others. It is especially useful for providers who don't use their ACLS knowledge regularly and may need reminders or closer guidance through the algorithm.
What personal information is captured? How is patient privacy handled?
The Code Blue Leader app does not collect or store any personal identifying information about users or patients. Past code logs contain a detailed record of the events that took place in a clear and anonymous way.
Are any other algorithms available?
Pediatric algorithms are in active development and will be added in a future update.
