The R's are currently bottom of the Premier League table with 17 points from their 26 matches.
However, despite their apparent bleak situation, Redknapp believes that a total of 20 points from their remaining 12 encounters could be enough for his side to retain their status as a top flight club.
"I think we need 20 points from our final 12 games to give ourselves a chance, to be honest," he told the club's official website. "If someone offered me 37 points now I'd probably take my chance and think that would be enough."
Next weekend QPR will play host to league leaders Manchester United.
