Townsend told the club's official website: "Monday's game is probably the fourth game in a row that people are calling must-win, but we're taking one game at a time.
"The gaffer has said he thinks 37 points might be enough and that's four wins and two draws, which we feel we are capable of achieving.
"That's what we're aiming for. We still believe and we'll be giving everything we can to stay up."
QPR are 19th in the Premier League and are seven points adrift of safety with eight games left to play this season.
