Kavanagh was without six first-team players for the goalless weekend draw against Brentford and is hoping to draft in much-needed cover ahead of the run-in.
"We've looked at a few potential signings already, but they haven't happened for us for whatever reason," Kavanagh told the club's official website.
"I do know that we need bodies in the building because of the injuries we've picked up.
"I'm doing all I can to get players in. I could gamble and take players I know nothing about, but you have to ask if they're going to be better than what we have.
"I have to get players in I feel will improve the squad. However, maybe we are getting to a stage where we have to take a calculated gamble.
"The amount of injuries we've had over the second half of this season is something I haven't seen before."
The Cumbrians boss also wants to extend the loan spells of both Sunderland goalkeeper Jordan Pickford and Manchester United striker Sam Byrne.
"We haven't spoken yet but I'd love to keep both of them for as long as I can," Kavanagh added.
"They've been great additions to the club and they are fantastic around the group. Hopefully we'll get to see them for a little bit longer."
