III.Cardiac output
IV.PCO₂ level

Question

Which of the following factors affect oxygen delivery to the tissues? I.Hemoglobin concentration II.Arterial hemoglobin saturation with oxygen III.Cardiac output IV.PCO₂ level

Quizplus · Accepted Answer

Factors that affect oxygen delivery (O₂ DEL) to the tissues include (1) hemoglobin concentration, (2) arterial hemoglobin saturation with oxygen (this automatically takes the PaO₂ into account), and (3) cardiac output ( $\dot Q $1 ). Because hemoglobin concentration, saturation, and PaO₂ determine the CaO₂, O₂ DEL depends on CaO₂ and $\dot Q $
