Question

What is the correct answer? I will thumbs up right answer

Joe's Arterial blood tests revealed the following: pO2 (partial pressure of oxygen in the plasma) 73 mm Hg (normal- 80-105 mm Hg) pCO2 (partial pressure of carbon dioxide in the plasma) 50 mm Hg (normal 35- 45 mm Hg) pH-7.32 (normal 7.35-7.45) Hb-02 sat (hemoglobin-oxygen saturation)-84% (normal 95-98%) In this case the His oxygen-hemoglobin dissociation curve would shift to the right, causing more O, to be released to his cells shift to the left, allowing less O2 to be released to his cells show no change, allowing the O2 concentration to remain stable.

Explanation / Answer

Here it is clear that partial pressure of oxygen is low which leads to left side shift of the curve.

Partial pressure of CO2 is slightly on the higher side but will not affect the curve as the increase in pCO2 is sloght.

pH is normal

Haemoglobin oxygen saturation is low which will again shift curve to left.

Left side shift of the curve resembles low partial presuure of oxygen, low haemoglobin oxygen saturation, higher affinity for oxygen ( higher binding capacity of Hb to oxygen) and decreased release of oxygen from Hb.

The answer is left side shift, allowing less release of oxygen to cells
