Conservative oxygen therapy with a target SpO2 of 90% did not reduce 90-day all-cause mortality compared to usual oxygen therapy in mechanically ventilated adult patients.

In children with septic shock and no known cardiac dysfunction, starting treatment with norepinephrine rather than epinephrine was associated with lower 30-day mortality.

Really cool study led by David Murphy on "apnea interval" - the interruption in ventilation due to intubation attempt during CPR. TL;DR: Shorter apnea interval associated with favorable outcomes.

Does VF on consecutive rhythm checks mean refractory or recurrent VF?
In this analysis of data from cases in the ARREST registry out of Amsterdam, only 5% (n=22) of cases remained in refractory VF after 3 shocks.
