I should think that it would be fairly obvious to any scientist, or even a med student, that with the percentage of oxygen not changing and the volume of lungs staying the same that there would be less moles of oxygen.
I was driving over the mountains in colorado n i felt like i was gonna pass out n my heart started beating so fast my whole body was shaky while driving n i knew i had to get to lower altitude so i continued driving has this happened to anyone. I live in colorado just at a lower altitude. When I am above 6k feet I eventually feel like the life force is leaving me and I return to lower altitudes asap.

People who do not spend enough time acclimatizing to a new altitude before progressing further have the highest risk of developing altitude sickness. The body may also respond to a change in altitude by altering blood acidity level, lung pressure, electrolyte levels, and fluid and salt balance.
Rising to higher altitudes can also cause fluid to leak from tiny blood vessels, resulting in a potentially dangerous fluid buildup in the lungs and the brain. The primary symptom of altitude sickness is a headache. However, many factors, including dehydration , can cause similar symptoms. As a result, a doctor will assess a range of criteria to reach a diagnosis. For a doctor to diagnose a person with altitude sickness, the person must have climbed to an altitude higher than 8, ft , present with a headache, and be experiencing other associated symptoms.
These symptoms may include dizziness, insomnia, and shortness of breath, among others. A person who develops any of these symptoms should immediately stop ascending and rest until their symptoms have cleared.
They may also benefit from descending to a lower altitude. People with very mild symptoms may continue ascending but should go at a much slower pace. However, if a person experiences even slight symptoms, they should alert others. Those with more severe symptoms should rest, consume plenty of fluids, and avoid anything that may affect blood oxygen levels, such as smoking. Descending: Moving to a lower altitude is usually the best action to take if a person develops symptoms of altitude sickness.
Once acclimatized they may be able to ascend once more. Pure oxygen: Giving pure oxygen can help a person with severe breathing problems caused by altitude sickness. Physicians at mountain resorts commonly provide this treatment. A Gamow bag: This portable, plastic hyperbaric chamber can be inflated with a foot pump and is used when a rapid descent is not possible. Painkillers: Acetaminophens, such as Tylenol, can be taken for headaches. Ibuprofen , an anti-inflammatory medicine, can also help.
However, this medication may cause some side effects, including a pins and needles feeling in the face, fingers, and toes, excessive urination, and blurred vision in rare cases. Dexamethasone: This is a steroid hormone that can suppress immune activity and inflammation. It can reduce the incidence of acute altitude sickness and other complications. However, the medication has some possible side effects, including stomach pain , depression , and euphoria.
Nifedipine: This is a dihydropyridine calcium channel blocker doctors commonly prescribe to treat high blood pressure. It is effective for treating fluid buildup in the lungs. This medication reduces the narrowing of the pulmonary artery, easing chest tightness and making breathing easier. More severe symptoms generally occur at over 12, ft. A lack of oxygen at high altitude combined with the subsequent changes in pressure within the blood vessels causes fluid to leak through tiny blood vessels into the brain, which leads to swelling.
