Question

directions: follow the link above to watch the pbs video. answer the following questions with c

1. what happens to the oxygen as you go higher in altitude?b
2. what is it like five miles above sea level?
3. what is hypoxia and what are its symptoms?

is it dangerous?

1. how does the hyperbaric chamber (gamow bag) work

Explanation:

1. As altitude increases, the partial - pressure of oxygen decreases, leading to less oxygen available for respiration.
2. Five miles (about 8 kilometers) above sea - level is in the stratosphere. It is very cold, has low air pressure and low oxygen levels.
3. Hypoxia is a condition where the body or a region of the body is deprived of adequate oxygen supply. Symptoms include shortness of breath, confusion, rapid heart rate, and in severe cases, can be life - threatening.
4. (No full question 4 text, but a hyperbaric chamber like a Gamow bag works by increasing the pressure around the person inside, effectively increasing the partial pressure of oxygen to levels more similar to lower altitudes, helping to relieve altitude - related symptoms.

Answer:

1. The partial - pressure of oxygen decreases.
2. It is cold, has low air pressure and low oxygen levels.
3. Hypoxia is oxygen deprivation. Symptoms include shortness of breath, confusion, rapid heart rate. It can be dangerous.
4. (Incomplete question, but generally) It increases pressure around the person to raise oxygen partial pressure.
