Little things can make a big difference when it comes to running
a code. EMS director and CPR aficionado Bill Reed gives a primer on
High Performance CPR.
High Performance CPR core principles
- Rate = 110 (100-120).
- Metronome set at 110.
- Depth = 2.0-2.5 inches.
- Full recoil (no leaning).
- Focus on rate & depth.
- Listen for 15 second countdown warning of upcoming compressor
- Change compressors at 2-minute intervals/cycles.
- Whenever possible, compressions performed from patient’s right
side and new compressor comes in from the previous compressors
right side. Opposite is true for left sided
- New compressor to “hover” over chest during rhythm check and/or
- No more than 5 second pauses for compressor change or rhythm
- Immediately resume CPR after defibrillation (no pulse checks)
or when rhythm check is complete.
- NRB or nasal cannula at max flow initially.
- BVM when available.
- Rate = 1 breath every 10 compressions (unsynchronized).
- Volume = no more than ½ ambu bag.
- ETI when feasible or if no ROSC by 6-8 minutes as resources
- ETCO2 monitor connected as soon as feasible.
- ETI should be accomplished by a provider other than code
- Hands off patient and/or airway device at 2-minute check.
- Attach as soon as possible.
- Standard pad placement.
- If witnessed VF while pads were in place for another reason,
immediate charge and defibrillate. Otherwise, ensure CPR for
at least 30 seconds before delivering any defibrillations.
- Pre-charge defibrillator 15 seconds prior to 2-minute
- If non-shockable rhythm at 2-minute check, “dump” charge by
pressing the decrease energy selection button.
- If shockable rhythm at 2-minute check, immediately defibrillate
& resume CPR (no pulse checks).
- If VF on rhythm check at 6 minutes (third cycle), immediately
defibrillate, then roll patient 30 degrees towards new compressor,
attach new posterior pad slightly below and medial to the patients
left scapula, roll patient back and resume CPR. Attach new
anterior pad over left superior chest. Connect new AP pads to
- At 8 and 10-minute checks (fourth & fifth cycles),
pre-charge and defibrillate with new AP pads &
monitor/defibrillator set at max joules.
- At 12-minute check (sixth cycle), pre-charge both
defibrillators to max joules and defibrillate both “simultaneously”
if patient is still in VF. One operator, two fingers.
- Changing to AP pads and/or double sequential defibrillation
(DSD) is only for refractory VF.
- If VF converts with standard pad placement, AP pad placement,
or DSD, use that pad placement and energy setting for recurrent VF
- IO is faster than IV.
- IV can follow IO.
- Central venous access should be accomplished by a provider
other than the code lead.
- Know your rhythm before giving drugs! That tachycardia
might be SVT or something that might not take kindly to a bolus of
- Goal is for 3 doses in first 10 minutes.
- Can give at 2,4, & 6-minute checks or whatever time
interval is most easily accomplished.
- After 10 minutes, goal is for Epi every 5 minutes.
- Amiodarone (for VF)
- Goal is for 2 doses in first 10 minutes.
- 300mg first dose and 150mg second dose.
- Can give at 2 & 6-minute checks or whatever time interval
is most easily accomplished.
Code Lead & Code Scribe/Time Keeper
- Confirm/ensure metronome use & appropriate CPR depth &
- Confirm/ensure appropriate BVM or BV ET Tube rate and
- Confirm/ensure ETCO2 connected and documented.
- Notify team of impending compressor change and rhythm check 15
seconds prior to the end of the 2-minute cycle.
- Confirm/ensure defibrillator is pre-charged.
- Interpret rhythm.
- Instruct defibrillator operator to deliver shock (or deliver
shock if code lead is the operator) after confirming no team member
is touching the patient.
- Confirm/ensure resumption of CPR and BVM after rhythm check
- Request and confirm drug delivery at appropriately
- Confirm/ensure documentation of rhythm(s) and drug doses.
- Ensure all pauses are less than or equal to 5 seconds (use 5
sec verbal count down).
