Emma Norton, aged 26, is admitted to hospital with an acute
exacerbation of her COPD. Using your knowledge of the respiratory
system (M2) and the cardiovascular system (M3), please answer the
following questions below. Be sure to clearly label the different
parts:
PART A / Emma undergoes a pulmonary lung function test. How
would her total lung capacity test and her FEV1/FVC values compare
to normal physiological values?
PART B / In hospital, Emma is placed on oxygen but develops
respiratory depression. Explain why Emma stops breathing when she
is administered oxygen.
PART C / Emma’s COPD has caused pulmonary hypertension and
subsequent failure of the right ventricle. What are the roles of
venous pressure and capillary hydrostatic pressure in causing
edema?
PART D /  Emma’s right ventricular failure has caused
a decrease in cardiac output. Explain which hormonal system will be
activated and how it compensate for this.
