This brief was updated on June 26, 2020, with data as of June 18, 2020. Overall findings remain consistent, but the percentage of patients with an unknown outcome has decreased from 34% to 6%.
Here we examine the mortality of patients who received invasive mechanical ventilation as treatment for acute respiratory failure due to COVID-19.
As of June 18, 2020, for COVID-19 positive patients age 19+ requiring invasive mechanical ventilation (n = 10,873), 4,989 (46%) were discharged from the hospital, 5,215 (48%) died, and 669 (6%) remain in the hospital.

The overall mortality rate in this sample of patients is between 48%-54%. Survival varies with age and sex, with younger and female patients having an increased likelihood of survival. Understanding ventilator survival rates by age and sex may be helpful for clinicians who are counseling patients and family members on likely outcomes with mechanical ventilation.
Data are pooled from 48 health systems representing 333 hospitals spanning 22 states and covering 42 million active patients.
