Understanding CNS Toxicity

CNS Toxicity or CNS % can be lethal and is caused by short to medium length exposures to high partial pressures of oxygen. This short video goes over the definition of partial pressure, how to calculate PPO2 for various oxygen blends, what CNS % feels like, and how to avoid it. #NEDU #NOAA #CNS

I’m a nitrox instructor and this information is accurate and detailed

Great explanation thanks.

[@TheCarefulDiver]

You're welcome!

[@AlexGarbino]

Great summary! Is there additional work being done in the topic?

[@TheCarefulDiver]

Yes. The 1.6 P02 limit is imprecise because it varies so widely in people, and within the same person from one exposure to the next. Understanding other factors, and getting better predictions is part of the work that has to be done.

My dive today I racked up cns 11053% I was @ 55’ for 110 min on 100% ppo2 of 2.6 😮 🤗

Why? What were you doing? That's intense.
