High Altitude (Definition)

As one ascends through the atmosphere, every breath contains fewer molecules of oxygen. One must work harder to obtain oxygen, by breathing faster and deeper. The % of oxygen in the atmosphere at sea level is 21%. As altitude increases, the % remains the same but the number of oxygen molecules per breath is reduced. At 12, 000 feet 40% fewer oxygen molecules per breath. Your ...Read more

How quickly can your hemoglobin rise in high altitude?

How quickly can your hemoglobin rise in high altitude?

Hemoglobin at altitu: Weeks to months depending on the altitude. The immediate response to altitudes over 10, 000 feet is an increase in the depth and rate of breathing to help maintain the level of oxygen in the blood. As the length of exposure persists, the kidneys will start producing a hormone to increase the rate of production of red blood cells to pick up and carry more of the available oxygen at that altitude. ...Read more

Could a lowlander adjust to permanently living at high altitude?

Could a lowlander adjust to permanently living at high altitude?

Certainly, Examples:: 1.Your bone marrow will makes more oxygen carrying red cells at altitude 2.The body produces more of a particular enzyme which increases release of oxygen from hemoglobin to the body tissues 3.Your kidneys adjust the acid base state of your body by changing amount bicarbonate (sodium bicarbonate) excreted. 4. Pulmonary capillary pressure increases, forcing parts of the lung to work that are dormant at sea level. ...Read more

Effects of living at high altitudes on the elderly - anything worrisome?

Low O2: High altitudes can be tough for elders, especially those with lung disease as the available oygen is less. Slow aclimation to high altitudes is vital to prevent serious problems including heart failure and brain swelling. Once an elder adjusts to the new altitude, there will likely be less problems. Similar situations can happen in flight for those with serious lung or heart conditions. ...Read more

Do people in high risk jobs experience a higher level of stress than people in low risk or zero risk jobs?

Do people in high risk jobs experience a higher level of stress than people in low risk or zero risk jobs?

Depends on you...: Stress levels are dependent on an interaction between many factors, including level of job risk, level of perceived risk, stress tolerance, personal resilience, abilities, and coping abilities. Depending on these variables, and others, a person at a high risk job may actually experience less stress than someone in a lower risk job. ...Read more

Can living at a higher altitude cause spontaneous pneumothorax?

Can living at a higher altitude cause spontaneous pneumothorax?

No: Pneumothorax is a risk with barotrauma occurring during rapid changes in pressure causing the lung to overexpand. For example if a scuba diver is at depth takes a deep breath and comes up from the high pressure depth to low pressure at surface, the lungs will overexpand. As pressure decreases, volume of air in lungs increase>barotrauma. Living at constant pressure at high altitude is ok. ...Read more

Is living in a high industry zone dangerous?

Is living in a high industry zone dangerous?

Environmental Prob: High industry areas could have issues with higher pollution problems with the air and water. High electrical plants might also cause emf problems for those that are sensitive to high electrical wave forms. There would also be more traffic in these areas and therefore, more potential for increased problems with pollution. ...Read more

What is high blood pressure in teenagers?

What is high blood pressure in teenagers?

A few causes: High blood pressure in teenagers is increasingly caused by the same problems that cause high blood pressure in adults. Sedentary lifestyle, poor diet or diets very high in sodium (salt), lack of exercise and obesity can all cause high blood pressure in teens. It is always worth getting it checked out by a doctor, sometimes it can be from kidney disease or other underlying problems with the body. ...Read more

Are oxygen saturation levels lower in the elderly?

Are oxygen saturation levels lower in the elderly?

Not necessarily: As we age, it may get a little harder for the oxygen to get into the blood through your lungs. But, as long as you have healthy lungs, the oxygen saturation levels can be normal well into one's 80s or 90s. ...Read more

Does rapid breathing at high altitudes results to respiratory alkalosis?

Does rapid breathing at high altitudes results to respiratory alkalosis?

Yes: Actually, since you're at high altitude the low pressures cause you to breathe faster to get enough oxygen and therefore you're blowing off co2 at a faster rate which results in a respiratory alkalosis. This can be prevented by a medication called Diamox (acetazolamide) and also controlling how high you ascend in a day. ...Read more
