For perspective on this 30 seconds business, the best median time to defibrillation for In-Hospital cardiac arrest you can find is about 1 minute. That's from a pool of a large amount of hospitals. When some quite renowned hospitals have looked at their data, some find it is actually 2+ minutes. That's in the hospital. That large pool study found that up to 40% of patients in an ICU, go over 2 minutes before being defibrillated. Those are scenarios where presumably patients are hooked up to continuous monitoring with alarms, and have the presence of both staff and equipment nearby to do the defibrillation.
Coming down hard on the people that were there last night and did what they could, simply from saying you view a clip, strikes me as unnecessary. They are professionals. I am sure there will be a debrief and a root cause analysis if warranted, and improvements will be made. Until then, a little grace for the people in the line of fire.
