Episode 8 – Oxygen Delivery After Cardiac Arrest Resuscitation

During cardiac arrest resuscitation, most patients are intubated and placed on 100% oxygen. In this podcast, Drs. Teran and Abella discuss recent investigations that suggest that too much oxygen may worsen post-arrest injury. Global resuscitation guidelines suggest down-titration of oxygen as tolerated to maintain adequate O2 saturation, but it’s not clear how well this is done- many patients are left on high oxygen “dose” for hours.
