before ERB 17,87%;
after ERB 34,22%.
During the before and after evaluation periods, other key system factors typically related to better outcomes remained constant, such as average EMS crew response intervals (6:35 min/s in 2014, 6:33 , 6:32  and 6:34  or the relative frequency of ECG presentations [VF/VT, asystole, pulseless electrical activity; p = 0.423]), gender (p = 0.685), arrest after EMS arrival (p = 0.386), and frequency of cases witnessed by bystanders (p = 0.362).
Good neurological outcome rates in patients successfully resuscitated at hospital arrival remains constant: 35-40%.
“The head-up/torso-up cardiopulmonary resuscitation bundle was feasible and associated with an immediate, steady rise in resuscitation rates during implementation followed by a sustained doubling of the number of out-of-hospital cardiac arrest patients being resuscitated. These findings make a compelling case that this bundled technique will improve out-of-hospital cardiac arrest outcomes significantly in other clinical evaluations. (Crit Care Med 2019; 47:449–455)”
