Perhaps you should try some spelling variations:
decreases during » decrease during (Expand search), increases during (Expand search), decreases lung (Expand search)
toc decreases » c decreases (Expand search), oic decreases (Expand search), co2 decreases (Expand search)
during object » using object (Expand search), moving object (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)

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

• Removing quotes may allow a broader search: (( decrease and decrease and decrease ) OR ( decrease toc decreases during object ))~.
