Code-blue documentation timer (AHA 2020)
Tracks the clock during a cardiac arrest.

Example
- Code start time
- 2026-05-19T12:00
- Last rhythm check at
- 2026-05-19T12:06
- Last epinephrine dose at
- 2026-05-19T12:04
- Last shock energy
- 200
- Cumulative cycle count
- 3
Result: Next rhythm check 12:08; next epi 12:08; last shock 200 J; AHA 2020 ETCO2 ROSC target >10 mmHg.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Rhythm checks
- q2 min per AHA 2020.
- Epinephrine 1 mg
- q3-5 min per AHA 2020.
- ETCO2 ROSC
- Sustained >10 mmHg (ideally >20) per AHA 2020.
What you enter
Code start time; the last rhythm check, epinephrine dose, and shock energy; and the cycle count so far.
What this is
Enter the code start time and the timestamps of the last rhythm check and last epinephrine dose, and it returns elapsed code time, cycle count, and when the next rhythm check and next epinephrine dose fall due, following AHA 2020 intervals. It also builds a printable timeline summary for the chart.
When to use it
Use it as the recorder's aid during a resuscitation and for documenting the timeline afterward. It computes intervals only; the code leader, the ACLS algorithm, and local protocol drive every decision, and the timer is never a prompt to give a drug or deliver a shock.
