So, just to be perfectly clear, as I have heard this in a round-about way from a few sources… We are not to use high concentration/High Flow oxygen via a BVM with a VSA patient without inserting an SGA – so when treating a VSA pt, we go directly to the SGA without ever using an OPA or NGA, correct? And what are our options if the SGA fails after 2 attempts and we do not have any extra hands to ensure a tight seal on the BVM mask – do we ventilate at all, or just administer compressions and carry on?
