The administration of Epinephrine 1 mg every 3 to 5 minutes has been the standard medication within the cardiac arrest algorithm. An option to provide epinephrine every four minutes as a midrange has been added. This allows the provider to administer epinephrine every other two-minute rhythm check.
Amiodarone and lidocaine change
Amiodarone and lidocaine are now considered equivalent in the treatment of ventricular fibrillation or pulseless ventricular tachycardia. Either amiodarone or lidocaine may be used.
Quantitative waveform capnography with a bag-mask device to confirm and monitor CPR quality is now recommended. Prior to the 2020 guidelines, the recommendation for quantitative waveform capnography monitoring was limited to monitoring only after endotracheal tube placement.
