Sea level is the level of the sea's surface. However this changes with the tides and with the weather conditions.Therefore Mean sea level (MSL), an average level of the surface of one or more of Earth's oceans is used as a datum from which heights such as elevations are measured.
The amount of oxygen you get with every breath at the peak of Everest is about 1/4 of what you get at sea level. At sea level, oxygen is about 21% of the gas you breathe. I don't know if that percentage changes with altitude.
