NB the third link is NOT a decompression clip - it shows the effects of anoxia.
I would suggest you try one of the military for training videos of decompression chamber runs. I believe RAF North Luffenham (as was?) would have had some and there have been some on UK TV programmes. The RAF training has been taken over, I believe, by The RAF Centre of Aviation Medicine at RAF Henlow - you could try there? The standard 'run' in my day was in one chanber at 25,000ft and a diaphragm then ruptured between us and a chamber at 100,000ft taking us to around 56,000ft I recall. Perhaps a little dramatic for airline crew, though
