Because oxygen is the combustion  fuel and glucose  is the substrate needed for synthesis of energy as ATPs during cellular respiration.Therefore Guillermo lacks enough energy as ATPs in her  body cells, especially skeletal muscles cells to complete the task of ascending the s steps.

For all the mitochondrial in cells(sites of energy production)   to receive needed glucose,and other metabolites needed for  energy synthesis; an efficient transport system is needed, so that  these materials   are available  immediately, in required amount. This system is called circulatory system.

And for the the supply of combustion fuel (oxygen) needed for the completion of the ATP synthesis mechanisms;  respiratory systems which  convey oxygen from the external environments to the circulatory system through breathing mechanisms, for distribution is needed.

Therefore in order  for the available  glucose, oxygen , co-factors,  and enzymes, needed for complete synthesis of ATPs   to be used efficiently for  energy synthesis, a step-wise , metabolic  reactions is needed  in the cells called  cellular respiration( respiratory system).

Thus the  doctor needs to test both the circulatory and respiratory systems.
