Question

ACTIVITY 8.2t year-old woman has been on a heavy menstrual period for 12 days. Her hemoglobin is drastically reduced (8 g/100 mL blood; normal female value 15 g/dL).Assume that Taking a Sample Clinical Case: A 27- lung functionality, Pao, and PA, are normal at 100 mm Hg, the lung O, binding capacity is 20.1 mL O/100 mln and her hemoglobin saturation is 96% at a partial pressure of O (PaO,) of 100 mm Hg. Use the step-by-step calculations discussed earlier in this chapter to calculate total O, content (normal O is 20.0-20.4 mL/O,/100 ml. blood). Explain 2 if the results are normal THIRD FINALLY FIRST SECOND CALCULATE 0 CALCULATE O2CALCULATE DIS- CALCULATE TOTAL O, CONTENT TOTAL O2 CONTENT = 0, CONTENT+ DISSOLVED O, CONTENT SOLVED O2 VALUE O, BINDING CAPACITY, CONTENT DISSOLVED 02 LUNG o, BINDING (o, BINDING CAPACITY)Po,SOLUBILITY × (HD SATURATION %) CAPACTY7x0PATIENT HB/ NORMAL Hb) 100 mL blood 100 mL blood 100 mL blood 1ml bloe

Explanation / Answer

oxygen binding capacity,

= (lung oxygen binding capacity x patient Hb)/ normal Hb

= (20.1 x 8)/15

= 160.8/15

= 10.72 ml of O2 per 100 ml of blood

O2 content,

= O2 binding capacity x hb saturation

= 10.72 x 0.96

= 10.29 ml of O2 per 100 mlof blood

Dissolved oxygen,

= PO2 x solubility

= 100 x 0.02

= 2 ml of O2 per 100 ml of blood

Total oxygen content,

= Oxygen content + dissolved oxygen

= 10.29 + 2

= 12.29 ml of oxygen per 100 ml of blood

The normal oxygen content is 20 to 20.4 ml of oxygen per 100 ml of blood. So, the results are below normal.
