the clip and the light that you are talking about is a pulse oximeter and this machine measure the hemoglobin that is bind to oxygen in your blood. The hemoglobin is what transport oxygen to your cells and tissues. If you have a low hemoglobin level but they're all bind to oxygen the reading will be good but your tissues and cells are not receiving enough oxygen. That can be one of the reason you're feeling you don't get enough air.
Otherwise it could be because of congestion in your lungs even if you're getting enough oxygen.
well, you don't breath carbon dioxide, you breath oxygen
Why would you become short of breath at high altitudes if air at those levels still contains 21% oxygen
It makes it hard to breath and, if severe, lowers oxygen levels.
Plants have a nearly opposite respiration with that of humans. They harness the energetic photons of sunlight along with the ability to fix carbon dioxide (CO2) in separate reactions to create carbohydrates (R-6-P) as the product and, to answer your question, Oxygen as the respiratory "waste" product. This fact is why you often hear people say that we need trees and plants to breathe and sustain oxygen levels at their optimal P02 levels of around 25-28%
If the patient blood levels fall (maybe due to hemorrhage), the oxygen that the RBCs are carrying is lost with the blood. The person will feel 'out of breath'.
Shortness of breath, COPD, asthma, and low oxygen levels to the body requiring oxygen therapy.
hi, as we breath in we breath in about 20% oxygen, we breath out 16%.. we only use about 4% of the oxygen we breath in..
A good way to measure dissolved oxygen levels in the human body would be to use a pulse oximeter. It is a little device that you can put on a finger or toe to get the measurement.
Answer: Because the percentage of oxygen in the air is not as much as it is at sea level. When higher altitude is attained, oxygen levels drop. Hope this helps.
When you hold your breath, CO2 levels will increase in your body, which, simply put, makes your body oxygen-starved. This, then, will trigger a reaction that will attempt to get as much oxygen throughout the body as possible, and this is done by increasing the heart rate.
Oxygen levels in the blood are measured with a pulse oxymeter that measures by shining a light through the finger tip, with or blood gas tests run in a laboratory. Lab could be venous or arterial, usually arterial.
there is no such thing because we breath oxygen and breath out carbon dioxide
