It depends a bit on the system used. If you are being supplied with air or oxygen via demand valve then your consumption will depend on your rate or breathing rather than the amount of oxygen biologically needed by your body. So clearly in this situation being able to control your breathing rate will help a lot. Humans, like most animals have a natural ...

In a situation with ample oxygen supply, I don't think any special technique would be necessary. In a limited and depleting scenario where you expect to come near to depletion; steady breathing, limiting talking, and excessive physical exertion will help extend that rate of consumption. Though inevitably as O2 saturation decreases, your body will suffer ...

As the elevation increases, the boiling point of water drops. This makes cooking times increase enormously. You may want to essentially ignore cooking, and rely on cold food, and warm drinks. The whisper light is a good stove for such events. I have also used regular gasoline at low temperatures, but due to the explosive nature of fumes, I would never ...

For cooking at cold and altitude, the pressurised liquid fuel stove is your friend. They're expensive and need some skill and care in use (practise before you take them into challenging situations), but they will perform much better than alcohol or canister stoves when the going gets tough. Here's a video that gives a good overview of how they are used. As ...

Both times I was severely sick for three days with migraine and vomiting compared to others with normal blood pressure. There has to be some connection between low blood pressure and severe altitude sickness.
