The oxyhemoglobin dissociation curveCurve 1 of 3 · Q 1/5

Hemoglobin saturation across a range of PO2 values. The solid curve is normal adult blood at rest; the dashed curve is the same blood under different conditions.

↑ Hemoglobin O2 saturation (%) · → PO2 (mmHg), 0 to 120

PaO2 falls from the value at point E to the value at point D. What happens to arterial O2 content?
