Figure 2
Representative plots of minimum average 30 minute SmO 2 for (A) a subject with no pleural effusion detected and (B) a subject with pleural effusion detected by ultrasound and chest x-ray. Fever time zero denotes the time of defervescence (temperature ≤38°C). PE = pleural effusion as measured by ultrasound; PEI = pleural effusion index as measured on right lateral decubitus chest x-ray.
