At high altitudes, hypoxia can occur because the percentage of O2 in atmospheric air is decreasedQuestion 16AnswerTrueFalse

On ascent to high altitude, there is a marked drop in Hb-O2 saturation, this drop can be explained by: (Select all that are correct. There may be one or more correct options)Group of answer choicesFall in temperature in the atmosphere creates a right ward shift of the Hb-O2 curveDecrease barometric air pressure means the air is less dense and thus the number of O2 molecules inspired with each breath is lessDecrease barometric air pressure decrease O2 partial pressure in the surrounding airPercentage composition of oxygen decreases with altitude, thus less O2 is inspired with each breath

The lower oxygen concentration at high altitudes makes you get out of breath easier. It can also cause headaches, nausea (feeling like vomiting), and ___.drowsinesssleeplessnessalertness
