I Asked Prof Simon Mitchell About The Helium Penalty

An interview with Prof Simon Mitchell, a decompression physiology and diving medicine researcher, about the helium penalty. They cover where the idea came from, the Bühlmann assumption about helium versus nitrogen kinetics, and what recent research suggests. The conversation also addresses why shorter decompression raises risk and why surviving a dive once proves little.

Why divers recommend it

Stands out as an expert-led look at the online debate over deep dives run with no helium programmed, giving technical divers using helium context from a leading voice in diving medicine.
