Rangers sit second bottom of the table and two points adrift of safety ahead of Saturday's London derby at home to West Ham.
Three points looks essential against the Hammers given QPR's next two matches are away to Manchester City and Liverpool, before they finish against Newcastle and Leicester.
"If you win three games you're probably going to stay up," Ramsey said.
"As long as we're above the line come the end of May we'll be happy.
"I just care if we win
I just take care of our own game
If we don't get good results it doesn't matter what the others do.
"We know the enormity of the task ahead but you can only plan and prepare as best you can and what happens, happens.
"We understand there is pressure in these last few games.
"I can't say I don't feel pressure but it depends on how you deal with it."
QPR have enjoyed an upturn in form, taking four points against West Brom and Aston Villa before conceding a last-minute goal to lose 1-0 against Chelsea last time out.
It was the seventh time this year QPR have conceded in the final 10 minutes of a match and Ramsey admits his side must improve their concentration.
"It is down to a lack of continued concentration," Ramsey said.
"Not many teams are getting slaughtered but the quality at the top end is why they are there.
"We're not happy with late goals
We need to stop conceding those late goals.
"We were quite frustrated at the end of the last game as we played well but didn't get a positive result."
Richard Dunne is fit again after recovering from a knee problem while Leroy Fer is also available.
Rio Ferdinand, however, is still out and Ramsey suggested the former Manchester United defender may not be fit enough to play again this term.
"Rio is still nursing a knock, unfortunately he's had it a long time," Ramsey said.
"He will be in contention to play again this season but we need fit players to play."
Ferdinand has said he intends to retire at the end of the current campaign.
The 36-year-old moved to Loftus Road on a one-year deal last summer but has made only 11 league appearances.
