"WebFirst, the relationship between Pa o 2 and Sa o 2 was nonlinear, as expected for the oxyhemoglobin dissociation curve (Figure 1A). Within the cyanotic range, a narrow range of Pa o 2 values corresponded with a wide range of Sa o 2 values; the more hypoxemic the patient, the wider the standard deviation in Sa o 2 (Figure 1B).
