What is oxygen treatment?

A gas: Oxygen therapy is usually given to people who have cardiac and pulmonary disease and have low oxygen saturations. The oxygen comes in a tank or concentrator and the flow is adjusted to deliver oxygen to keep a specific blood saturation above 88. ...Read more

Does bronchiolitis cause low oxygen saturation?

Does bronchiolitis cause low oxygen saturation?

It happends: Bronchiolitis causes a build up of secretions in the tiny airways and blocks transfer of oxygen into the tissues. It can and does cause a drop in blood oxygen in many cases. ...Read more

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

Can COPD patient on oxygen get carbon monoxide poison?

Not usually: Carbon monoxide is found in cigarette smoke, out of car exhausts, and other places. Simply being on oxygen doesn't mean that you can get carbon monoxide poisoning, unless you get exposed to it. ...Read more

Can shallow breathing (anxiety?) reduce oxygen saturation?

Can shallow breathing (anxiety?) reduce oxygen saturation?

Shallow breathing: Will lower oxygen level. We often rib cage breathe when anxious. Please learn some belly breathing and you will increase your oxygen level. Peace and good health. ...Read more

Is hyperbaric oxygen therapy raise blood pressure?

Is hyperbaric oxygen therapy raise blood pressure?

Usually Not: Hyperbaric oxygen does not usually raise ones blood pressure. If your blood pressure is above normal than it is usually due to some other condition. See your family physician to discuss this. ...Read more

Help docs, is hyperbaric oxygen therapy the same as breathing oxygen through an oxygen tank?

Help docs, is hyperbaric oxygen therapy the same as breathing oxygen through an oxygen tank?

Hyperbaric vs oxygen: No, it is not. Oxygen with a mask or nasal cannula supplied by a tank is not delivered under pressure. Hyperbaric chambers deliver oxygen under pressure so that the level of oxygen in the body tissues exceeds those values that oxygen is delivered via sea level. ...Read more

Could low oxygen (decreased lung expansion) decreases cardiac output?

Could low oxygen (decreased lung expansion) decreases cardiac output?

Possible: The heart needs oxygen as fuel to do its job. If oxygen is very low, the heart may not pump as well. ...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

Can oxygen help in treating carbon monoxide poisoning?

Can oxygen help in treating carbon monoxide poisoning?

Yes: Carbon monoxide (co) stays tightly bound to hemoglobin, forming carboxyhemoglobin. Co comes off the hemoglobin gradually as the hours go by. Studies show carboxyhemoglobin's half-life to be about 4 hours (3-5 hr) in regular air, but about 1 hour (30-90 minutes) when breathing 100% oxygen for treatment of co poisoning. Increased oxygen makes the co come off the hemoglobin and leave the body sooner. ...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
