He used what he knew about the TOP management team to convince them to ratchet up the number of patients each physician had to see in a given period to increase profits.
第一部分what 引导的宾语从句：He used what he knew about the TOP management team
to convince them 不定式做宾补
to ratchet up the number of patients each physician had to see 这句话和两个不定式干什么成分我实在看不多，
in a given period to increase profits.是状语，不定式做名词成分
He主语 used 谓语 what he knew about the TOP management team 宾语 括号内部分为不定式短语作sued的目的状语。
在这个不定式短语中， to ratchet up the number of patients each physician had to see in a given period to increase profits为convince的宾语补足语。其中each physician had to see in a given period为定语从句修饰patients。to increase profits为ratchet up的目的状语。
