CRITICAL LEVELS - THE PODCAST -
“Critical Levels” is a new podcast dedicated to having critical conversations in paramedicine created for paramedics, by paramedics, with a Canadian and local bias.
The opinions and discussion within the podcast are meant as educational material for paramedics, and it is not meant to establish a standard of care – please do not deviate from your local medical directives.
We hope to release monthly episodes, but we are in this together – please reach out with ideas for guests and topics.
In addition to the podcast, which will be availiable across all podcast platforms, this website serves as a central location for episode summaries and resources.
There are several theories that suggest why double sequential defibrillation and/or vector change defibrillation may be effective.
Energy theory: increased energy delivery allows for defibrillation of a critical mass of myocardium terminating the refractory VF.
Setting up theory: the first shock reduces the threshold and results in a more successful second shock.
Multiple vector theory: change in pads (or additional pads) changes the energy vector defibrillating parts of myocardium not adequately defibrillated in standard position.
