•Once the trachea has
been intubated, chest compressions, at a rate of 100 a minute, should continue uninterrupted (except for defibrillation or pulse checks when indicated), and
ventilation should be continued at roughly 12
without interruption for ventilation result in a substantially higher mean
coronary perfusion pressure.
•new guidelines include the option to use biphasic shocks. In
defibrillation, success rates of repeated
biphasic shocks at £ 200J are the same as or
higher than success rates of monophasic waveforms of escalating energy (200 J, 200 J, 360 J).
