Compression rate

AHA target 100–120/min
110 /min pacing beat

Starts pacing once compressions are running.

Depth
5–6 cm (at least 5 cm, no more than 6 cm)
Ratio
30:2 until an advanced airway is in place
With advanced airway
Continuous compressions, 1 breath every 6s
Guideline reference used by this timer
  • • Compression rate 100–120/min, depth 5–6 cm (at least 5 cm, no more than 6 cm), full recoil, ratio 30:2 until an advanced airway is in place.
  • • Rhythm reassessed every 2 minutes; keep every interruption under 10 seconds.
  • • Epinephrine (adrenaline) 1 mg IV/IO every 3–5 minutes — as soon as feasible in asystole/PEA, after failed defibrillation in VF/pVT.
  • • Amiodarone 300 mg (then 150 mg) or lidocaine for VF/pVT refractory to shocks.
  • • With an advanced airway: continuous compressions and 1 breath every 6 seconds (10/min).
  • • Search the reversible causes (Hs and Ts) throughout the arrest.
