I do think that may have helped in this situation. In a more broad sense my point is I would be disappointed if a paramedic didn’t do something to stop someone from dying. We don’t have to agree on the administration of sedatives but I’d rather me or my family be sedated and transported to the hospital instead of situations continuing to escalate while fighting with law enforcement that may lead to someone being killed.
To be clear, I don’t know the full details of this specific case, as I said in my original comment, there isn’t a reason I can think of for the medics not monitoring capnography, that’s industry standard as it will show in real time when someone stops breathing and allow us to take over. If the paramedics did not monitor capnography and the patient died then that is most likely negligence that resulted in someone’s death which is unacceptable. However if they did everything appropriately and recognized the change in condition and addressed it and the patient still died then then it’s hard to fault them, apart from giving the incorrect dose of ketamine, tho just giving an extra 200mg of ketamine will not cause someone to die but it can cause unwanted side effect that if unrecognized or untreated could lead to someone’s death.
