Final answer:
To calculate Qs/Qt in this scenario, use the formula Qs/Qt = (A-a)O2 / C(a-v) and substitute the given values of (A-a)O2 and C(a-v) into the formula to obtain the desired value.
Step-by-step explanation:
Calculation of Qs/Qt:
Qs/Qt can be calculated using the formula Qs/Qt = (A-a)O2 / C(a-v), where (A-a)O2 represents the alveolar oxygen pressure and C(a-v) represents the difference in oxygen content between the alveolus and the pulmonary artery. In this case, if (A-a)O2 is given as 300 torr and C(a-v) is given as 3.6 vol%, we can substitute these values into the formula to calculate Qs/Qt.
Calculation:
Qs/Qt = (A-a)O2 / C(a-v)
Qs/Qt = 300 torr / 3.6 vol%
Qs/Qt = 83.33 torr/vol%
