Relating oxygen partial pressure, saturation and you will content: the brand new haemoglobin–oxygen dissociation curve

In clinical practice, the level of arterial oxygenation can be measured either directly by blood gas sampling to measure partial pressure (PaOdos) and percentage saturation (SaO2) or indirectly by pulse oximetry (SpO2).

New haemoglobin–outdoors dissociation curve outlining the relationship ranging from oxygen partial pressure and saturation might be modelled mathematically and you can regularly gotten clinical studies assistance the accuracy out-of an old picture regularly define it hinge sınavları relationships.
