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 bloeExplanation / 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.
