Figure 3From: 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 conditionsPao 2 /Fio 2 ratio in different types of lung conditions at three PEEP levels. 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; Pao2, arterial oxygen tension; PBW, predicted body weight; PEEP, positive end-expiratory pressure.Back to article page
