One person was purported to survive 7 days in the desert, 6 of these without water, without suffering heat stroke as the temperature reached no higher than 103.2 °F (39.6 °C) during his ordeal. [9] However, he had reached the third stage of dehydration, which is 80-90% fatal; this likely represents an upper limit of survival at high temperatures.
Room air at altitude can be enriched with oxygen without introducing an unacceptable fire hazard. At an altitude of 8000 m the equivalent altitude in terms of oxygen partial pressure can be reduced to below 4000 m without increasing the fire hazard beyond that of normal sea level atmospheric air.
The time a choking victim is still alive without brain damage [15] can vary, but typically brain damage can occur when the patient remains without air for approximately three minutes (it is variable). Death can occur if breathing is not restored in six to ten minutes (varies depending on the person).
Some scientists estimate that in case of the most ideal conditions people can live up to 127 years.

The life-support system may supply air, water and food. It must also maintain the correct body temperature, an acceptable pressure on the body and deal with the body's waste products. Shielding against harmful external influences such as radiation and micro-meteorites may also be necessary.
