Blackburn boss Steve Kean admitted his side missed a chance to take a "big leap" towards Premier League safety after their third consecutive draw.
Junior Hoilett cancelled out Lee Bowyer's opener at the end of the first period, but the second half proved a pressure-filled affair with few clear-cut chances.
"I wanted to take a big leap today but we're taking little steps and we just have to keep chipping away," said Kean. "If all the teams around you pick up wins and you only get a point you're massively disappointed. But today we're probably a little bit better off than when we started."
Kean reserved particular praise for Hoilett, who pounced on an error by Liam Ridgewell to burst clear and round goalkeeper Ben Foster before slotting home.
"Junior has shown he can play on any side and if you're a defender and he's running at you he can petrify you with his touch and his pace."
However, the hard-earned point came at a price with Hoilett limping off with a tight hamstring and Ryan Nelsen and Roque Santa Cruz also having to leave the pitch early.
Injury problems also continue to hit Birmingham's bid for survival, with central defender Roger Johnson forced off after suffering a slight concussion in a first-half melee.
