What is the partial pressure of oxygen on Mt Everest if the atmospheric pressure on Mt Everest is one-third the atmospheric pressure at sea level?
The partial pressure of oxygen on Mt Everest would be approximately one-third of the partial pressure of oxygen at sea level, assuming a constant composition of air. This decrease is due to the decrease in atmospheric pressure at higher elevations. This lower partial pressure of oxygen can lead to decreased oxygen availability for breathing at high altitudes.
What is the particial pressure of oxygen?
The partial pressure of oxygen is a measure of the pressure exerted by oxygen in a mixture of gases. In atmospheric air at sea level, the partial pressure of oxygen is around 160 mmHg. The partial pressure of oxygen can also be calculated using the equation: partial pressure of oxygen = total pressure of gas mixture * mole fraction of oxygen gas in the mixture.

How would gas exchange be affected at the top of a tall mountain where air pressure is lower and there is less oxygen then at lower elevations?
At high altitudes, atmospheric pressure is lower. Therefore, the partial pressure (partial oxygen) is lower. As partial pressure of oxygen goes down, the body's desire for oxygen goes up.

An airplane is pressurized to 650 mm Hg which is the atmospheric pressure at a ski resort at 13000 ft altitude If air is 21 percent oxygen what is the partial pressure of oxygen on the plane?
To find the partial pressure of oxygen, we first need to calculate the total pressure of the air in the airplane cabin using Dalton's law of partial pressures. Given that the atmospheric pressure at 13000 ft altitude is 650 mm Hg, the partial pressure of oxygen can be calculated as 21% of this total pressure since oxygen constitutes 21% of the air. Thus, the partial pressure of oxygen on the plane is: 0.21 * 650 mm Hg = 136.5 mm Hg.
How can the effects of changes in atmospheric pressure be reduced?
Mountaineers often take oxygen tanks when they climb high mountains such as Everest. The tanks contain oxygen gas that has been compressed into small volume. This can help reduce the effect of atmospheric pressure
What is the partial pressure of oxygen in blood gas a mixture of N2 O2 and CO2 if the partial pr. of Nitrogen 630 mm of Hg and partial pressure of CO2 is 39 mm of Hg?
To find the partial pressure of oxygen, we need to subtract the partial pressures of nitrogen and CO2 from the total pressure of the mixture, which is typically around 760 mmHg at sea level. Therefore, the partial pressure of oxygen would be 760 - 630 - 39 = 91 mmHg.
What is the atmospheric pressure if the partial pressure of nitrogen oxygen and argon are 442mm Hg 118.34mm Hg and 5.66mm Hg respectively?
These three components are the three largest components of air. The total pressure of a gas mixture is just the sum of the partial pressures of each component. Air is a mixture and nitrogen, oxygen, and argon are the three biggest components. So, the atmospheric pressure (or air pressure) would be the sum of the partial pressure of each component of the air: Ptot=PPnitrogen + PPoxygen+ PPargon = 442 mmHg + 118.34 mmHg + 5.66 mmHg = 566 mmHg
Why is the partial pressure of oxygen in tissue lower than the partial pressure of oxygen in the blood?
The partial pressure of oxygen in tissue is lower due to oxygen being delivered from the blood to the tissues for cellular respiration. As tissues consume oxygen for metabolic processes, the partial pressure decreases. Additionally, factors like distance from capillaries and tissue oxygen consumption rate impact the partial pressure of oxygen in tissues.
How much oxegeon is on top of mount Everest?
The atmospheric pressure at the top of Mount Everest is about a third of sea level pressure or 0.333 standard atmospheres (337 mbar), resulting in the availability of only about a third as much oxygen to breathe.
How does partial pressure of oxygen change as altitude changes?
The percentage of oxygen in the air is for the most the same in the entire atmosphere.It is only in the very high altitudes that the percentage of oxygen actually diminishes. This because it is heavier than the helium and hydrogen that is up there.What matters however is the pressure of the air.At high altitude you breathe less oxygen because pressure is lower.At low altitude you breathe more oxygen due to higher pressure.The pressure of the atmosphere drops by approximately 50% every 18.000 feet (5.600 Meters, 5.6 Kilometer's)Oxygen, being a gas, exerts a partial pressure, which is determined by the prevailing environmental pressure. At sea level, the atmospheric pressure is 760mmHg, and oxygen makes up 21% (20.094% to be exact) of inspired air: so oxygen exerts a partial pressure of 760 x 0.21 = 159mmHg.The partial pressure does not actually change much at all with altitude since the percentage of oxygen remains the same.Our body however (with altitude) utilizes less oxygen because there is less of it and this effectively reduces partial pressure of oxygen in our bodies.Read more on related link down below.
