Here's 名乗り(readings specific to names) for both kanji. Some of them are rarely ever used, though.
保: お, たもつ, ほ, ほう, まもる, もち, もり, やす, やすし, より
節: お, さだ, せつ, たか, たかし, たけ, とき, とも, のり, ふ, ふし, まこと, みさ, みさお, みね, もと, よ, よし
Thus, 保節 can have dozens of possible readings, as Glenn-san and epigene-san wrote.

(What came to my mind before consulting a dictionary was やすとき for 保節.)
