Perhaps you should try some spelling variations:
decrease pulmonary » decreases pulmonary (Expand search), increased pulmonary (Expand search), increases pulmonary (Expand search)
pulmonary objects » pulmonary effects (Expand search), pulmonary spect (Expand search), primary objects (Expand search)
decrease any » decrease and (Expand search), decreases and (Expand search), decreased and (Expand search)
any decrease » and decrease (Expand search), can decrease (Expand search), may decrease (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (Expand search)

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease any decrease AND decrease ) OR ( decrease NOT decrease pulmonary objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease any decrease AND decrease ) OR ( decrease not decrease pulmonary objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease any decrease AND decrease ) OR ( decrease not decrease pulmonary objects ))*.
