Hemodynamics during mechanical CPR


Synopsis

Per-Olav Berve is a Norwegian anaesthesiologist who works for the Oslo air ambulance and in-hospital at the Oslo University Hospital. He is currently wrapping up a PhD on CPR physiology, focusing on multimodal monitoring. His main project is a OHCA study on mechanical active compression-decompression CPR.

Tailored or targeted CPR and resuscitation is a very popular concept with a lot of traction currently. In this talk from The Big Sick in Zermatt in 2018, Per details insights from his research that cautions us when choosing targets to titrate to. There’s more to the eye than sheer numbers, it turns out. Learn how your pattern recognition abilities may beat any monitor on the market.

Scott Weingart recently did an emcrit podcast with PO specifically on this topic of diastolic pressure targets during CPR. A lot more to be learned there including advice on how to apply this in practice.
