Figure 5From: How large is the lung recruitability in early acute respiratory distress syndrome: a prospective case series of patients monitored by computed tomographyIndividual variations of PaO 2 /FIO 2 ratio, before and after MRS. The red dashed line represents the threshold of 200. Whereas the baseline blood gas was collected at 100% oxygen fraction, the second one, collected at the titrated-PEEP, was collected at an average FIO2 = 45% (± 17%).Back to article page
