QPR have dropped 13 points from winning positions at Loftus Road this season and had five players sent off at home, three in their last four fixtures.
As a result, only goal difference separates QPR from the relegation zone and they face an ominous run-in, including facing six of the top seven teams in the league.
Hughes believes QPR have the quality to win their battle against the drop - providing they stop shooting themselves in the foot with red cards.
"We haven't helped ourselves because we haven't managed to keep 11 players on the field and that has hurt us in too many games," said Hughes, who will be without the suspended pair Samba Diakite and Djibril Cisse. "In three of the last four home games we have gone down to 10 men and it is very difficult to overcome those differences at Premier League level.
"We want to keep 11 on the field of play, that will help us significantly. We need to start getting points on the board. I remain convinced we have enough quality in the club to stay up. We have to make sure we emphasise that fact by getting the points on the board. We need to be competitive in the league but we need to keep people on the field of play. If we do that in our home games we will pick up more than enough points."
