No abstract

The original article contains a mistake in the appendix section. On page 1186, last point in appendix currently reads "Worsening gas exchange [e.g., O 2 desaturations (e.g., PaO 2-FiO 2 ≤ 240), increased oxygen requirements, or increased ventilation demand]." It should be corrected as "Worsening gas exchange [e.g., O 2 desaturations (e.g., PaO 2 / FiO 2 ≤ 240), increased oxygen requirements, or increased ventilator demand].
