In medicine, while performing an arterial-blood gas test, physicians measure the partial pressure of carbon dioxide and oxygen. With these measurements, they can calculate the pH of their patient's blood. You might find it surprising that air pressure changes with altitude and temperature. It's...
I study genotype-environment associations in alpine species. I frequently see altitude as the sole predictor of partial pressure of oxygen in the literature concerning hypoxia adaptations. However, I understand that partial pressure of oxygen is also influenced by temperature, humidity, and... ...
How much oxygen is in the air at sea level? What is the pressure in the abyssal zone? Is sea level pressure the same as air pressure? Below which altitude measurement is 50 percent of Earth?s atmosphere found? What is the relationship between temperature and altitude in the troposph...
The reduction of oxygen levels is a technique used both for fire fighting and fire protection in confined spaces. The purpose of this study was to find out if and how reduced oxygen levels affect cognitive performance in a small group of persons living in a confined space such as a submarine...

1. Gaseous compound Q contains only xenon and oxygen. When 0.100 g of Q is placed in a 50.0 mL steel vessel at 0 °C, the pressure is 0.229 atm. When the vessel and its contents are warmed to 100 °C, Q decomposes into its constituent elements. What is the total pressure, and wha...
alives 4500 m above sea level. The liver graft was harvested at sea level and transferred to our surgical facility at 3658 m above sea level. Long-term hypoxemia and low blood partial pressures of oxygen (PO2) of the patient after transplantation delayed the recovery of liver function from ...
Oxygen pre-breathing (OPB), a standard approach to remove dissolved N2 from tissues in anticipation of exposures to sub-normal pressures associated with high-altitude aviation and extra-vehicular transits while in space, is one of those strategies [21]. OPB has been associated with a decreased ...
