Figure 2From: Surfactant disaturated-phosphatidylcholine kinetics in acute respiratory distress syndrome by stable isotopes and a two compartment modelTracer to tracee ratio plot. Tracer to tracee ratio (ttr) in disaturated-phosphatidylcholine and palmitate isolated from tracheal aspirates in ARDS (upper) and controls (lower). Values are mean ± SEM. n = 7 for control subjects and 12 for patients with ARDS.Back to article page
