Body weight is a predictor of biphasic shock success for low energy transthoracic defibrillation

RECOVER evidence and knowledge gap analysis on veterinary CPR. Part 4: Advanced life support

“…Niemann et al (LOE 6, good/supporting) found that defibrillation was more successful with BP and there was less evidence of ST segment changes after ROSC with BP . Zhang et al (LOE 6, good/supporting) evaluated the success of MP versus BP defibrillation in a model of LV dysfunction and identified better success with BP defibrillation . Tang et al (LOE 6, good/supporting) found that pigs were more successfully defibrillated with BP than MP defibrillation at lower energies and had less myocardial damage …”

Hyperventilation-Induced Hypotension During Cardiopulmonary Resuscitation

“…5 If resuscitation was successful, animals were ventilated with a ventilator and supplemental oxygen. Return of spontaneous circulation (ROSC) was defined as a palpable pulse over 5 minutes.…”

Dual defibrillation in out-of-hospital cardiac arrest: A retrospective cohort analysis

“…13,14 Alternatively, others hypothesize that defibrillation is a weight based treatment and larger individuals simply may require more joules. 15,16 The last leading theory for DSD efficacy is that the therapy changes the vector of the therapy and the shock is given over a longer duration. 8 DSD was first developed and tested in canine models of refractory VF.…”
