When he was swallowed, how did Burt stay alive so long inside the Graboid?

We do try to work out the details on every bit of action.  Note that Burt takes cover inside an oil drum as he is swallowed.   So a little air is trapped with him.  He mentions that he has “limited air” on the radio.  Also, a person can survive at least three minute without air.  From the time he is swallowed til the time he is cut out of the Graboid is 3 minutes and about 14 seconds, actual screen time, although in “movie” time it does feel longer.  Finally, Burt plans for everything, and has probably done breath-holding exercises like deep sea free divers, right?
