There is always a debate in the ED that should we send a patient status post ROSC to cath lab or not. JAMA in July 2022 published a French national multicenter study regarding OHCA patient who had a ROSC to assess cerebral performance category. They enrolled 279 patients and they measured 180 days survival rates. As a conclusion they did not find emergent cath lab activation to be better than delayed cath lab intervention.
