Dah ada kajian yg di buat tunjukkan pesakit2 yg kronik lebih mudah mati apabila di beri oksigen secara supplementary seperti yg di beri di ICU2 lani tu ler
Oxygen therapy, also known as supplemental oxygen, is the use of oxygen as a medical treatment. This can include for low blood oxygen, carbon monoxide toxicity, cluster headaches, and to maintain enough oxygen while inhaled anesthetics are given.

Liberal Use of Oxygen Increases Risk of Death for Acutely Ill
Researchers have found oxygen therapy increases risk of death when given liberally to patients with acute illness, such as heart attack, stroke, and trauma.
“The feeling of it to my lungs was not sensibly different from that of common air; but I fancied that my breast felt peculiarly light and easy for some time afterwards,” wrote Joseph Priestley, a chemist and theologian, in 1775. What he described was the sensation of inhaling oxygen, which he’d managed to produce through the chemical reaction of heating mercuric oxide. Priestley predicted this “pure air” might one day serve a medical or therapeutic purpose. And he was right, but about a century and a half too early.
The use of oxygen only became common in medical practice in 1917, with the publication of The Therapeutic Administration of Oxygen, by John Scott HaldaneTrusted Source, a Scottish physiologist.
In the past one hundred years, oxygen therapyhas grown from a nascent, untested intervention to a ubiquitous practice in homes and hospitals across the world.
But now, a landmark study published in the journal The LancetTrusted Source is causing doctors to take a second look and reconsider how safe it really is. The study concludes that oxygen therapy increases risk of death when given liberally to patients with acute illness, such as heart attack, stroke, and trauma. “It’s been the general thought of many clinicians that oxygen is not a harmless intervention, however the available evidence, until we published our study, was not definite,” Waleed Alhazzani, an assistant professor in Critical Care at McMaster University and an author on the paper, told Healthline. “It seems that giving more oxygen than needed can actually increase death in the hospital,” he said. Alhazzani and his team of researchers conducted a meta-analysis reviewing 25 randomized controlled trials, including roughly 16,000 patients, comparing “liberal therapy” (using supplemental oxygen) and “conservative therapy” (room air or minimal oxygen intervention). They found that for every 71 patients treated with liberal oxygen therapy, an additional death occurs. “The idea that we could be administering excess oxygen and that could be causing harm is certainly something that’s not widely understood,” said Dr. John William McEvoy, an assistant professor of cardiology at Johns Hopkins University. “This [study] is really going to raise a flag that hasn’t been raised before and hopefully will lead to a wider understanding and acknowledgement that we should consider how much oxygen we’re giving,” he said.
