I presume Boba suffered from some oxygen starvation and his memory of escaping the Sarlacc was swiss cheesed as a result. There may have not have been much air left in that dead trooper’s suit to begin with.

As an example, I had really bad asthma attacks as a little kid, and was rushed to the ER more than once. My parents kept a small emergency oxygen tank handy that looked to me like a green cartoon bomb after that. I have no memory of ever being in the ER at that age though. Probably a good thing.
