Newcastle United finally stopped their run of eight straight defeats by drawing with West Bromwich Albion at the weekend.
Newcastle ended a run of straight eight defeats by drawing 1-1 with the Baggies, and Perez believes that it is a result which they can build upon.
The Spanish striker, who scored the Magpies' goal in the match, believes that the whole squad are more positive after this weekend's point and they want to secure their safety by beating Queens Park Rangers in their next match.
"We were definitely after the three points, but that point is very important at this stage," he said. "It has given us a lot of confidence, but we need to focus on the next game against QPR and go after those important three points.
"We have to go full steam ahead against QPR. It is a crucial game - very important - and we need to go there and get the three points."
Newcastle actually dropped to 17th place in the Premier League table after their draw with the Baggies, but Hull City are the only team in the relegation zone who can catch them.
The Tigers have tough games against Tottenham Hotspur and Manchester United remaining, meaning that Newcastle should only need to beat already-relegated QPR or out-of-sorts West Ham United to confirm their safety.
Doing so will be easier said than done, though, as Newcastle have been woeful under John Carver's stewardship so far.
The Magpies look under-motivated and poorly organised and unless they raise their performance levels then their safety still looks far from secure.
