Cole is confident West Ham can cause an upset at Arsenal on Wednesday.
He said: "We should have won. We got lots of crosses into the box but credit the QPR defence - they held strong.
"We have to try to take the positives, though. It's another point on the board and another step towards safety. We'll go to Arsenal on Wednesday in good spirits and try to put in a good performance. I think 38 points will probably be enough [to stay up] this year.
"We're going there to win, it has been done before. They have great footballers, Jack Wilshere, Theo Walcott and the rest. You have to go there and try to stifle them. We'll always be a threat, especially from set pieces."
