What exactly is oxygen toxicity?

What exactly is oxygen toxicity?

Resp arrest.: Pts. With COPD have a problem in letting the co2 out from their lungs. Co2 measurements at the level of the brainstem send a message to the brain and lungs to breath slower or faster. When too much oxygen gets in, the stimulus of co2 stops then the lungs stop moving since there is plenty of oxygen ( respiratory arrest). COPD patients that retain co2 cannot get concent. Of o2 >2 lts. X min. ...Read more

I am on oxygen 24/7 is that to much oxygen?

Depends: What are your saturations? You should keep them around/above 90% then you are getting just enough and not too much. I strongly recommend investing in a pulse oximeter, as medicare does not pay for oxygen at night and as needed as we used to prescribe before. Now the only way you can get oxygen is if you get a prescription for 24/7. ...Read more

For normal patient who does not smoke very low oxygen level could be defined as an oxygen saturation less than 88% or a partial pressure of oxygen measured in blood gas less than 60 mmhg. For an active smoker these numbers may be different. For someone with underlying lung disease again these numbers may be lower. ...Read more

How does the body use oxygen ususally?

OXYGEN for ENERGY: Biochemically, oxygen (o2) is required for energy production for every living cell. Oxygen is transported by the blood bound to hemoglobin (red pigment in red cells). Oxygen is then delivered to the cells via simple diffusion. Oxygen is taken up by the mitochondria of the cells where oxidation and phosporylation are coupled to make atp (energy molecule). Oxygen converted to h20 in process. ...Read more

Are novelty oxygen bars as effective as medical oxygen treatments?

Are novelty oxygen bars as effective as medical oxygen treatments?

Absolutely not: Oxygen bars needlessly separate you from your money, or are just downright harmful. Life evolved to tolerate oxygen long before it evolved to thrive in it. As such, most life on land does best when o2 is at environmental levels (21%). Higher levels can be toxic and, over a long time, accelerate aging. Fortunately, most o2 bars "sell" air identical to what you breath on a city street. ...Read more
