Figure 2From: Erratum to: End-expiratory lung volume during mechanical ventilation: a comparison with reference values and the effect of positive end-expiratory pressure in intensive care unit patients with different lung conditionsMeasured EELV as percentage of predicted sitting FRC at three PEEP levels. The black dotted line represent predicted sitting FRC (100%). Patients in group N had normal lungs, those in group P had a primary lung disorder, and those in group S had a secondary lung disorder. Values are expressed as mean ± standard deviation. EELV, end-expiratory lung volume; FiO2, inspired oxygen fraction; FRC, functional residual capacity; Pao2, arterial oxygen tension; PEEP, positive end- expiratory pressure.Back to article page
