Oxygen therapy is generally safe, but has some known side-effects. These include a dry or bloody nose, tiredness, lung burn, and morning headaches.

The benefits of oxygen therapy in patients with COPD outweigh the modest risk of burn injury associated with home oxygen use. However, with the increasing number of patients being prescribed oxygen, health care professionals must educate and counsel patients regarding the potential risk of burn injury.

Patients with lung disease experiencing difficulty breathing can be treated with oxygen therapy. This involves the delivery of "extra" oxygen by a face-mask or through small tubes placed in the nose called nasal prongs. This extra oxygen can have concentrations as high as 100% pure oxygen. The concentration of oxygen in normal air is only 21%. The high concentration of oxygen can help to provide enough oxygen for all of the organs in the body. Unfortunately, breathing 100% oxygen for long periods of time can cause changes in the lungs, which are potentially harmful.

For your other conspiracy theories I need to prepare more data than just a simple academic search. For instance, are you aware that Bill Gates blocked open-sourcing the Oxford vaccine? Do you know why his wife divorced him? When dealing with possible misinformation, it is needed to keep an open mind. If you just say: it is 100% impossible for Bill Gates to have been involved in the pandemic-planning, pancorona-vaccine program which moved to China, and any coverup where he had more information about COVID than the public, but choose not to share for ulterior motives. Then it will remain a 100% no matter what. That's dogma, and it is misinformation for everybody else.

Here's another one for you: Mary Maxwell Gates(Bill Gates' mom) is the largest shareholder in Pfizer and is personally lobbying governments to buy the Pfizer vaccine, even though she died almost 30 years ago.

For that angle:

> Just before breakfast on the morning of March 4, Private Albert Gitchell of the U.S. Army reports to the hospital at Fort Riley, Kansas, complaining of the cold-like symptoms of sore throat, fever and headache. Soon after, over 100 of his fellow soldiers had reported similar symptoms, marking what are believed to be the first cases in the historic influenza pandemic of 1918, later known as Spanish flu. The flu would eventually kill 675,000 Americans and an estimated 20 million to 50 million people around the world, proving to be a far deadlier force than even the First World War.

> A REPORT ON ANTIMENINGITIS VACCINATION AND OBSERVATIONS ON AGGLUTININS IN THE BLOOD OF CHRONIC MENINGOCOCCUS CARRIERS. By FREDERICK L. GATES, M.D. First Lieutenant, Medical Corps, U. S. Army. (From the Base Hospital, Fort Riley, Kansas, and The Rockefeller Institute of Medical Research, New York.) (Received for publication, July 20, 1918.) ... An officer in Group II had reacted severely to the typhoid and paratyphoid vaccinations developed a severe local and general reaction, with headache and malaise, after the first injection of 750 million cocci ... From this time on, a small number of the men in each group reported some local or general discomfort following the vaccination. The symptom most frequently mentioned was a "feverish sensation" often accompanied by headache, which was sometimes severe enough to cause loss of sleep.

> When the United States entered WWI in April 1917, the fledgling pharmaceutical industry had something they had never had before: a large supply of human test subjects. During the war years of 1918 to 1919, the U.S. Army ballooned to 6 million men, of which 2 million were sent overseas. The Rockefeller Institute for Medical Research took advantage of this new pool of human guinea pigs to conduct vaccine experiments. ... According to a 2008 National Institute of Health paper, bacterial pneumonia was the killer in a minimum of 92.7% of the autopsies of those who died of so-called “Spanish flu” between 1918 and 1919.

> Vaccination is one of the most successful immunology applications that has considerably improved human health. The DNA vaccine is a new vaccine being developed since the early 1990s. Although the DNA vaccine is promising, no human DNA vaccine has been approved to date. ... Briefly, as a DNA vaccine carrier, bacteria are divided into two major groups: non-pathogenic bacteria and attenuated pathogen bacteria. The attenuated bacteria that have been studied as the DNA vaccine carrier include Salmonella spp., Yersinia enterocolitica, Shigella spp., and Listeria monocytogenes. Pathogen bacteria target the mucous membranes as their infection route and as a result, they are suitable for mucosal administration. However, the main disadvantage includes the likelihood of causing infection, particularly in infants and immunocompromised patients.
