Beside above, is high flow oxygen dangerous? High flow nasal oxygen is a promising approach to prevent reintubation, but it should be used carefully in high-risk patients. Post extubation is a hazardous period for ICU patients and ARF after planned extubation is associated withremarkably high mortality.

What is considered high flow oxygen?
What is considered high flow oxygen? High-flow nasal cannula (HFNC) therapy is an oxygen supply system capable of delivering up to 100% humidified and heated oxygen at a flow rate of up to 60 liters per minute. Keeping this in view, how many Litres is high flow oxygen?
Can too much oxygen be harmful?
When people are critically ill or have chronic lung disease, they often require additional oxygen to properly oxygenate the blood and tissues. In extreme cases a patient may require 100% oxygen. That is to say that they are breathing in pure oxygen. Like all drugs, too much can be harmful and dangerous.
Is nasal high flow oxygen therapy (hfot) safe and effective?
Short-term nasal highflow oxygen therapy (HFOT) is safe and efficacious in normocapnic and hypercapnic COPD patients. Background Nasal high-flow oxygen therapy (HFOT) is a novel non-invasive alternative to conventional oxygen treatment (COT) and an alternative to non-invasive ventilation in selected patients.
What happens if a patient is left on oxygen for too long?
If left for a prolonged period of time the patient can suffer permanent lung damage. The general rule is that a patient should be on the least amount of oxygen necessary to keep their blood-oxygen levels high enough to properly supply the tissues and organs.
