Severe hypoxemia without evidence of tissue hypoxia in adult respiratory distress syndrome.
A patient with severe arterial hypoxemia in adult respiratory distress syndrome (ARDS) secondary to a fractured femur is reported. A marked discrepancy between the clinical condition and laboratory findings was observed. At one point, PaO2 was below 4 kPa (30 mm Hg) on F1O2 0.21 without signs of tissue hypoxia. This patient illustrates beneficial effects of a leftward shift of the oxyhemoglobin dissociation curve.
