The Lions have a massive injury toll at present, with both Jonathan Brown (hip) and Mal Michael (ribs) late withdrawals from Saturday night's loss to the Western Bulldogs at the Gabba.
Matters only got worse during the game with Troy Selwood concussed after hitting his head on the ground in the first term and Ash McGrath appearing to badly injure a hamstring in the last quarter.
"The medical staff have a big job on their hands to get everyone up and running for after the bye," Charman said.
"It's going to be an interesting time for the club and us and hopefully we can get through it and get a few players back after the break.
"There were a fair few key players out and certainly that makes a difference. Big Mal back there would have played on (Chris ) Grant and that would have been a key match-up.
"After the bye we'll have Browny and Mal back and that will help things. Overall we've had an up and down first half of the year but hopefully we can pull through and we've got six winnable games and we'll take it from there."
The Bulldogs were far more clinical in converting their opportunities - particularly in the first-half - and Charman said better finishing was a must for the Lions.
"They moved the ball pretty quick from the kick-ins and were able to get a lot of space in the forward line," he said.
"All you can do is practice and do the extras. Shermo (Justin Sherman) missed one through the middle (in the first quarter) and it would have been good at that time to kick a few goals.
"But that wasn't the case and the Bulldogs' skill level was really good."
Charman returned from a one-week suspension to gather 17 possession and had 23 hitouts opposed to 211cm Western Bulldogs beanpole Peter Street. He said Street's height advantage - Charman is listed at 197cm - made him a tough match-up.
"He jumped well in the centre. He jumped high and hard tonight and he was a good competitor in the second bounce," Charman said.
The media attention surrounding the relationship between Leigh Matthews and reigning club best-and-fairest Jason Akermanis again hit overdrive this week in relation to an email reportedly sent by the player's brother Rory - but from Jason's email address - criticising the Lions coach.
But Charman, as Matthews did at his Friday media conference, downplayed the supposed furore and said it was no big deal and had not affected the playing group in any way.
"To be honest I've only read something in the paper and it hasn't been discussed amongst the players," he said.
"I think it got sorted about between Leigh and Aka and I haven't heard any of the players talking about it."
Also like Matthews, Charman believes Akermanis will stay a Lion next year and said the 2001 Brownlow Medalist was an important part of the future at the Gabba.
"He's going to help this team push further and he's a sensational player. Of course I'd like him to stay," Charman said.
