Once you are admitted to icu I wonder what the chances are of recovery at that point
There is a study in the Lancet about the recovery of critical condition (as opposed to merely serious) from a hospital in Wuhan. They defined it as needing oxygen above a certain level or mechanical intervention with breathing. After 28 days 67% were dead. Most who survived were younger than 50. If you needed mechanical help with breathing then you had an 80% chance of death. Again those who survived were in the younger groups.
Long and short if you are over 60 and need mechanical ventilation, it looks like you are more or less fucked.
So in terms of shortages of equipment, arguably you have to allocate on basis of who has the best chance of survival...
132 cases in Italy. 26 serious. 2 in Venice now.
