A normal, healthy individual has a blood oxygen level between 95 and 100 percent. When that level is pushed up above that baseline, it’s indicative of hyperoxemia, or excessive oxygen in the bloodstream. “Often times, when providers see an oxygen saturation of 100\%, they are delighted. That’s great.

How long does it take to get oxygen toxicity?

Pulmonary Toxicity Pulmonary toxic effect of oxygen can arise after prolonged exposure to oxygen > 0.5 ATA. Symptoms appear after a latent period whose duration decreases with increase in PO2. In normal humans the first signs of toxicity appear after about 10 hours of oxygen at 1ATA.
