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

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

How does the body use oxygen ususally?

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

Does increasing oxygen work if patient is in respiratory distress and if they have low hemoglobin?

It does.: It will help if the patient o2 saturation is low. You would like to see it between %96-100 by adjusting o2 flow of 1-2 lit per min. But the main goal should be raising the hemoglobin to normal level. ...Read more

Is there any research in the works to reduce the stress of copd...Ie: get rid of oxygen?

Always: There are numerous studies going on for copd. Newer medications come out every few years and advances over the past 10 years have dramatically improved COPD management. Unfortunately there hasn't been many breakthroughs yet in repairing the damage, only preventing worsening. Don't smoke, continue to get regular check-ups (including breathing tests - pfts), and keep your fingers crossed. ...Read more

Why is too much oxygen dangerous?

Oxygen toxicity: Hyperoxia likely exists whenever oxygen tension exceeds 21% of atmospheric pressure. It appears to produce cellular injury through increased production of reactive oxygen species, such as hydrogen peroxide, superoxide anion, and hydroxyl radical. Oxygen toxicity refers most commonly to resulting tracheobronchial injury and damage to the tissue of the lungs. ...Read more

Are repetitive mild aspiration pneumonias, life threatening? Recovers fast with antibiotics and oxygen.

Not good: I ask why. Do they occur at night (gerd), do you have trouble swallowing, hiatial hernia;perhaps overweight. The fact that this is occuring, and that you recover fast does not mean that you always will. Should these episodes become more severe and as you get older, your treatment options may become limited. Get the cause worked up and decide what to do with you pcp. ...Read more

What are the risks or possible side effects of hyperbaric oxygen therapy? Does it hurt? And what side effects are there?

What are the risks or possible side effects of hyperbaric oxygen therapy? Does it hurt? And what side effects are there?

Treatment: Treatment of hyperbaric oxygen therapy (hbot) is generally safe and painless.

The most common side effect would be the risk of injury to your ear drums during the compression phase of the treatment. This is because compression of the hyperbaric chamber is similar to when an airplane lands, or when you dive to the bottom of a swimming pool. As pressure builds up outside of the ear, you will have to equalize pressure by "popping" your ears. If you can do this, there should be no problems. If you cannot because you have a cold, aren't paying attention, or because you are not properly trying to equalize pressure, you can have pain, bleeding, swelling, or in a worst case scenario - rupture of the ear drum. These can all be easily avoided by communicating with your hyperbaric chamber operator, who will monitor your progress and adjust your compression or decompression rate. If you cannot successfully equalize your ears, you may be referred for pressure equalization tubes, which will eliminate this risk.

You may have similar discomfort in your sinuses, which is more difficult to manage because it is not possible to actively equalize pressure in your sinuses. In this case, your treatment may have to be postponed until you can decreased the amount of inflammation around your sinus cavities.

People who get hbot may also be at risk to damage to their lungs if there is a history of spontaneous collapse of the lungs, or damage to the lung tissue such as emphysema or COPD or asthma. If you have any history of lung disease, you should tell your treating physician ahead of time so that they can screen you for safety.

We have noticed that there are some people who develop mild nearsightedness as a result of hbot. This usually is in the elderly or diabetic patient but can happen to anyone who has had a multi-week series of hbot. These effects are generally temporary and revert back to pre-hbot vision. You should be aware of these changes so that you can plan for alternative transportation in case your vision changes. You should not have to get new glasses, as vision will generally return to baseline after you have stopped your hbot.

As with any medication, too much medicine may result in an toxicity. In the case of oxygen, you can get a case of oxygen poisoning of the brain, which could result in a seizure. This seizure is strictly related to the oxygen and will stop once the oxygen levels are decreased. You won't have to take any medications or be at any higher risk of seizures in the future. The risk of an oxygen induced seizure has been estimated to be about 1 in 3, 000 to 1 in 5, 000 treatments. Your treating physician may modify your treatment profile to use less oxygen, or institute more frequent or longer air breaks to temporarily lower the dose of oxygen to your brain. ...Read more

What effect does oxygen from an oxygen generator have on the respiratory system?

What effect does oxygen from an oxygen generator have on the respiratory system?

None: An oxygen concentrator simply provides a higher level of oxygen to the lungs than room air can. It has no effect on the lungs themselves. It can be very helpful if a person's oxygen level is too low from either lung or heart disease. ...Read more

I have grand mal seizure whenever I get one it lasted between 5to10 min. Does not having oxygen to my brain for so long cause damage?

I have grand mal seizure whenever I get one it lasted between 5to10 min. Does not having oxygen to my brain for so long cause damage?

Hopefully not: Grand mal seizures that last over 20 min are seen as a risk for brain damage, but shorter ones are not considered to be a risk for that. Here's a link: However, it is still important that you work w/ your physician on achieving the best management you can. Talk with them about your concern and best treatment planning. I hope it goes well. ...Read more

How many minutes without oxygen does it take before a child suffers permanent brain damage?

How many minutes without oxygen does it take before a child suffers permanent brain damage?

What is oxygen therapy and why is it used in treating diving accidents?

Oxygen for diving: Hyperbaric oxygen is used to "displace" nitrogen that accumulates in the blood during dives where you breath compressed air. Nitrogen is less readily dissolved in your blood, and can "bubble up" (open a bottle of soda or beer, and the co2 bubbles up- "carbonation"). Nitrogen bubbles in the blood cause "the bends" (e.g. Pe painful joint involvement, or serious brain involvement causing a stroke). ...Read more

Can you die from to much oxygen?

Oxygen Toxicity: Normal room air is 21% oxygen. That will not hurt you. Diving with 100% oxygen can cause some respiratory problems. Prematures on extra oxygen can develop serious eye problems. Hyperbaric oxygen, for a long time (maybe 12 hrs or more) can hurt you.
Most of these situations will not kill you.
Also severe fires are accelerated by excess oxygen, so smoking on oxygen has killed people. ...Read more

Is 2 liter a low dosage on oxygen?

Is 2 liter a low dosage on oxygen?

2liter a volume, not: A dosage. Dosage=a quantity per unit time. 2 Liters/min oxygen flow by nasal cannula is a commonly used adjunctive oxygen flow for people with lung ventilation/perfusion problems: https://en. Wikipedia. Org/wiki/Ventilation/perfusion_ratio. What counts is oxygen saturation of hemoglobin as percentage, not dosage. Too much oxygen, esp. Over days/weeks, is also toxic; yet uncommon without intubation. ...Read more
