As an example, even if the PO2 reaches as low as 50 to 60 mmHg, the oxygen saturation can remain at 85% - 90%. That is an indication that even though the oxygen levels are quite low, the saturation will be nearly normal. Clinically, this means that the patient has very little oxygen in reserve.

19. Why does PaO2 have to fall below 60 mmHg to cause noticeable changes in ventilation? a) we generate most of our energy via anaerobic means b) because our chemoreceptors respond to CO2 first c) O2 is not sensed by the central chemoreceptor d) we only use oxygen when PaO2 is less than 60 mmhg e) when PaO2 is above 60 mmhg there is not much benefit to increasing ventilation 20.

(Resources: Challenge Question and Reading Question #15 on page A-76 and the answer to that question on A-81 of the Course Pack) A) peripheral chemoreceptors B) central chemoreceptors Peripheral chemoreceptors would be stimulated due to arterial PO 2 less than 60 mmHg and Il valore di pO2 riscontrato deve essere sempre confrontato con la percentuale di ossigeno che il paziente sta respirando. Per capire meglio quest'ultima affermazione facciamo un esempio. Consideriamo la seguente emogas in tre tipologie di pazienti differenti: pH = 7,45 (vn 7,35 - 7,45) pO2 = 85 mmHg (vn > 60) pCO2 = 37 mmHg (vn 35-45) Because the functional hemoglobin is nearly 100% saturated, we do expect a pO2 of near 100 mm Hg(figure 2). Indeed if the hemoglobin saturation is 98%, the predicted pO2 is 95 mm Hg. As a side note, in the absence of lung disease, hypoventilation or environmental hypoxia, the pO2 is also expected to be normal in cases of methemoglobinemia.
