Not sure whether it’s applicable here. But when learning scuba diving, we were taught (or rather reminded of, from middle school physics) that a balloon would become bigger as one gets closer to the surface. A balloon 90m under water will be 10X the size when it’s at surface. Therefore, using a balloon for emergency surfacing will lead to a monotonically increasing acceleration rate (which means you’ll going be too fast), or probably bursting the balloon half way through.

Looking up the numbers, it seems the pressure at the Titanic is about 400bar, while the pressure of a CO2 cartdrige is about 800bar, so that works. About the baloon becoming larger as it surfaces, a pressure release valve that vents the baloon based on the pressure differential with the exterior (water) may do the trick.
