Flatliner helps trained emergency physicians, nurses, and paramedics record CPR and code blue events and prepare documentation. Record medications, rhythms, shocks, pulse checks, procedures, and key timestamps during a resuscitation. Review the event timeline afterward, generate a CPR summary, then review, edit, copy, or share the text for documentation. Choose the session mode that fits your workflow: • Standard tracks compressions and chest compression fraction (CCF). • Separate timers provides a separate timer layout. • Logging only focuses on event recording without tracking compressions or CCF. Configure voice, notification, and haptic reminders. Adjust cycle and epinephrine voice volumes separately, try reminder previews, and enable optional antiarrhythmic medication alerts. Notification previews stay separate from a live session. Other features include CPR and compression timers, a metronome, a CCF calculator, code history, and light and dark mode. Review generated notes against the clinical record before use.

It does not diagnose rhythms, interpret a patient's ECG, determine treatment, confirm a pulse, measure compression quality, confirm airway placement, or calculate doses. It does not replace clinical judgment, formal resuscitation training or certification, institutional protocols, or team leader decisions. The practice tools are for learning and do not grant or replace certification.
