... 1. Hyperoxygenation: The delivery of 100% oxygen under pressure (1.5 to 3 ATA) within the hyperbaric chamber provides up to 20 times normal oxygen to all tissues within the body. This oxygen super saturation is in marked contrast to breathing room air (21% oxygen at 1 ATA). 2. Direct Pressure to Oxy ...

Organisms at high altitude
.jpg?width=300)
Organisms can live at high altitude, either on land, or while flying. Decreased oxygen availability and decreased temperature make life at high altitude challenging. Despite these environmental conditions, many species have been successfully adapted at high altitudes. Animals have developed physiological adaptations to enhance oxygen uptake and delivery to tissues which can be used to sustain metabolism. The strategies used by animals to adapt to high altitude depend on their morphology and phylogeny.
