The following link and excerpts are from an early study of the Seattle area hospital that had many (most?) of the people from the Life Care center. It seems that being put on a ventilator gives you a 24% chance of survival if you are in that demographic.
Excerpts:
A total of 21 cases were included (mean age, 70 years [range, 43-92 years]; 52% male). Comorbidities were identified in 18 cases (86%)....
The mean onset of symptoms prior to presenting to the hospital was 3.5 days, and 17 patients (81%) were admitted to the ICU less than 24 hours after hospital admission....
Mechanical ventilation was initiated in 15 patients (71%) (Table 2). Acute respiratory distress syndrome (ARDS) was observed in 15 of 15 patients (100%) requiring mechanical ventilation and 8 of 15 (53%) developed severe ARDS by 72 hours....
As of March 17, 2020, mortality was 67% and 24% of patients have remained critically ill and 9.5% have been discharged from the ICU.

“In the state that saw the nation’s first confirmed covid-19 case on Jan. 31, and the first recorded coronavirus-related death on Feb. 29, initial dire predictions of massive spikes have waned even as testing has increased rapidly. While the number of cases in Washington state grew by as much as 28 percent in one day on March 15 — it has since slowed significantly statewide, as have hospitalizations and deaths.
State authorities said there have been 2,580 positive cases and 132 deaths, and as testing in Washington has ramped up, the percentage of positive cases has remained low — holding at about 7 percent. “
