Another thrilling Clasico ended in a 2-2 draw at Camp Nou on Sunday as Barcelona remained on track to finish the Liga season unbeaten.
But Real angered the hosts after refusing to kick the ball out with Suarez on the ground injured as they pushed for a winner.
However, Ramos had no regrets afterwards, saying the Uruguayan's history meant Real had no intention of stopping play.
"Whenever someone gets hurt on the pitch and we think it's serious, we kick the ball out," he said.
"It's a mark of respect.
"But knowing what he is like, his style and how he is, I didn't think it was necessary to do so."
Real had already refused to provide Barca with a guard of honour for their rivals' La Liga title success.
Suarez opened the scoring at Camp Nou as the 10-man hosts twice went ahead before holding on for a point.
Cristiano Ronaldo made it 1-1 with a finish from close-range before Barca's Sergi Roberto was sent off for a clash with Marcelo.
Lionel Messi fired the Liga champions back in front after 52 minutes but Gareth Bale's brilliant finish earned Real a share of the spoils.
