Depending on the area seen in an individual picture, brown, yellow and green continents can be seen or parts of Earth can be covered by white clouds. Earth is by far the most dynamic planet when seen from space.
Oxygen therapy is a medical treatment. It must be prescribed by a doctor. For people with COPD, oxygen therapy can be a helpful part of their treatment plan. The prescription your doctor writes will include: If you need oxygen for rest, exercise and/or sleep, and how much in liters per minute (lpm) for each activity.
Generally oxygen is not covered by insurance and not prescribed unless the saturation is <89% (and we inpatient doctors need a result from the day of discharge and not before). For Medi-Cal insurance, they require an actual blood gas showing the hypoxia. To answer your question, it's hard to say.
