==Conclusion==
Overall, I think the AltoLab is a cost effective and useful way of training for high altitude conditions, and possibly for improvements at sea level. I suspect that the downsides of using other intermittent systems will be similar to AltoLab. From what I understand from other people who've slept in altitude tents, there are different, but equally significant downsides to that approach, including poor sleep quality.
==Usage==[[File:HypoxiaWithAltoLab.JPG|none|thumb|800px|Example of O2 saturation from an AltoLab training session. The green vertical line marks the end of the hypoxic time and the red vertical line marks the beginning of the hypoxic time. The red line is O2 saturation, with the green fill showing above 90%, blue fill showing 90-75% and the pink fill showing below 75%. The blue line is heart rate.]]
