CPR Assist: ALS/ACLS Metronome

In cardiac arrest it is rarely the knowledge that makes the work hard - it is everything happening at once. The cycle is running, someone asks when adrenaline was last given, the shock count no longer matches, and afterwards the times for the report are missing. CPR Assist takes over that part: the app structures the workflow along the 2025 resuscitation guidelines for adults - either ERC / ALS (Europe) or AHA / ACLS (USA) - and records every step with a time stamp.

IMPORTANT - WHAT THIS APP IS NOT
CPR Assist is a cognitive aid and an event log for trained professionals. It is not a medical device and does not diagnose, treat, cure or prevent any medical condition. It gives no patient-specific advice and replaces neither training nor clinical judgement. Responsibility stays with the treating team. No paediatric mode: adult resuscitation only.

THE CYCLE AT THE CENTRE
A large ring counts down the two minutes. The last ten seconds warn visibly, then the analysis window prompts for the two things nobody thinks of under stress: check the rhythm, change the person compressing. The shock button is held instead of tapped - against accidental triggering; every shock increases the counter and starts the next cycle.

METRONOME AND TEMPO
The built-in CPR metronome keeps the beat for chest compressions: tempo 100, 110 or 120 per minute, audible and with a visual pulse. Support, not quality control.

DRUGS AS A STATUS
Adrenaline shows what the elapsed time means: too early, due, overdue. In a non-shockable rhythm as soon as possible; in VF/pVT after the third shock (ERC) or the second (ACLS), then every 3-5 minutes. Amiodarone is a dose status: 300 mg after the third shock, 150 mg after the fifth.

REVERSIBLE CAUSES AND INTERVENTIONS
The 4 H's and 4 T's - 5 H's and 5 T's in ACLS - as a working state instead of a tick list: open, checked/unlikely, suspected/treated, with a hint and a note. Access, airway, intubation, capnography or a mechanical CPR device go into the log with one tap.

CORRECTABLE WHILE THE CASE RUNS
The undo button takes back the last action - a shock with its cycle, a dose, an intervention. The live log shows the case with clock times; mistaken entries can be deleted, counters and status recalculate without them.

AFTER ROSC IT CONTINUES
ROSC opens a dedicated mode: airway, SpO2 target 94-98%, normocapnia, cause finding, 12-lead ECG, circulation, temperature. On re-arrest one button leads back into CPR - the adrenaline clock keeps running correctly.

TRAINING AND SIMULATION
In simulation training the app runs exactly as on a real case: the metronome keeps the tempo, cycles and drug status structure the scenario, the log carries the debriefing - from megacode training to team drills. CPR Assist is not a patient simulator; it keeps the beat, the structure and the record.

TWO GUIDELINE STANDARDS
Selectable on the start screen: ERC / ALS or AHA / ACLS, both resting on the ILCOR consensus. Switching changes the first adrenaline dose in VF/pVT, the reversible causes and the targets after ROSC. In ACLS you can also choose whether amiodarone or lidocaine carries the drug card. Free of charge.

TAKE THE REPORT WITH YOU
Every case can be named and exported as a PDF or image - with a summary and the complete log. The report is created on the device and leaves it only once you pick a destination.

ALSO INCLUDED
Six languages, following the device language on first start. Under "Guidelines and sources": publisher, date and link of the 2025 ERC or AHA guidelines plus ILCOR - and all the values the app calculates with.

NO PATIENT DATA, NO ACCOUNT
No details about patients; log and settings stay on the device. No account, no server, no tracking, no advertising. One voluntary one-off purchase, no subscription.

All information without warranty. What counts are the applicable guidelines and the decision of the treating team.
