Key result
Simultaneous compression and ventilation with abdominal binding increases cerebral blood flow to ~32% vs conventional CPR.
Why the study?
It was uncertain whether cerebral blood flow is enhanced by simultaneous chest compression and lung inflation with abdominal binding during CPR, given the transmission of intrathoracic pressure fluctuations to intracranial pressure.
Does simultaneous chest compression and lung inflation with abdominal binding improve cerebral blood flow in pentobarbital-anesthetized dogs with induced ventricular fibrillation compared to conventional CPR?
Does simultaneous chest compression and lung inflation with abdominal binding improve cerebral blood flow in pentobarbital-anesthetized dogs with induced ventricular fibrillation compared to conventional CPR?
Absolute Event Rate: 32% vs 3%
Simultaneous chest compression and lung inflation with abdominal binding substantially improves brain perfusion compared to conventional CPR in a canine model of cardiac arrest.

Hypothesis-generating for augmented CPR techniques; prospective human trials needed before any practice consideration.
Koehler et al. (1983) studied Cardiac arrest. Simultaneous chest compression and lung inflation with abdominal binding (SCV CPR) vs. Conventional CPR was evaluated on Cerebral blood flow (% of prearrest cerebral flow). Simultaneous chest compression and lung inflation with abdominal binding significantly increased cerebral blood flow compared to conventional CPR (32% vs 3% of prearrest flow).
