Assuming villain is semi conscious, he will fold to any bet unless he hit his flush, in which case he is silently praying that you will attempt to steal it so he can check raise you.
You should have 2 thoughts here
1 He hit his flush
2 He didn't flush
He may have paired or even set the board.
If you bet the previous bet of $22 and he hit his flush, he will raise and you can go into Marlon Brando mode, put on an act, then shove.
If you bet that same $22 and he was fishing, then he folds.
But you want value here. How about half the previous bet? $11. He might have paired, and a retrenchment like that might suggest you were fishing, and only have ace high. In that case he raises, and you go for a pissing contest, minraising him back. Praying he will do likewise. I think the potential for a big pot here makes this alternative attractive.
