From: Non-invasive ventilation for acute hypoxemic respiratory failure: intubation rate and risk factors
Box-plots indicating the median delay (25thto 75thpercentiles) between NIV initiation and intubation in patients intubated within the first 96 h. The time to intubation was similar in survivors (at left) and non-survivors (at right). Only five patients (three survivors and two non-survivors) were intubated beyond 96 hours.
