Is it possible to get Oxygen Toxicity with LiveO2 or ExtremeO2?

Oxygen Poisoning

In 1947 the British mil­i­tary dis­cov­ered that oxy­gen could be tox­ic,Oxygen Toxicity, as a result of under­wa­ter research. The same research dis­cov­ered that Nitrogen (78% of air) caused Nitrogen Narcosis.

In sim­ple terms, oxy­gen tox­i­c­i­ty only occurs under extreme­ly ele­vat­ed oxy­gen par­tial pres­sures.

This research deter­mined that super-con­cen­trat­ed oxy­gen, 18x nor­mal (impos­si­ble with­out mil­i­tary-grade equip­ment or deep div­ing), pro­duces oxy­gen poi­son­ing.

  • Ardenne’s pro­to­cols use oxy­gen at far less than these lev­els, and have nev­er been report­ed to cause harm or pro­duce oxy­gen tox­i­c­i­ty symp­toms, in any per­son.
  • Athletic pro­to­cols, have over a 75% safe­ty mar­gin; and non-ath­let­ic pro­to­cols have a 95% safe­ty mar­gin. A detailed analy­sis fol­lows.

According to the research doc­u­men­ta­tion, oxy­gen tox­i­c­i­ty effects can­not occur with Oxygen Multstep Therapy or LiveO2 sys­tems because they can­not pro­duce high enough lev­els of oxy­gen for a long enough peri­od of time to pro­duce these effects.

The Summary

If you want to skip the details, the results below come to 17.9 atmos­pheres, or breath­ing air under water of 538 feet. This is extreme.

For com­par­i­son, Ardenne’s preg­nan­cy sup­port pro­to­col uses about 4 atmos­pheres of oxy­gen for 15 min­utes dur­ing labor pre­ceed­ing child­birth. This is about 125 feet of water breath­ing reg­u­lar air, for a short peri­od of time.

His quick pro­to­cols use about 60% oxy­gen for 15 min­utes. The LiveO2 sys­tem sup­ports Ardenne’s high­est lev­el pro­to­cols for ath­let­ic train­ing and labor.

The high­est oxy­gen lev­els that any OMST sys­tem are capa­ble of are less than 1/4 the oxy­gen par­tial pres­sures known or ever report­ed pro­duce any oxy­gen tox­i­c­i­ty effect in any per­son. There are no reports, over the past 30 years, that any of Ardenne’s pro­to­cols have ever caused any sign of oxy­gen tox­i­c­i­ty in any per­son.


Oxygen at sea lev­el is 1 atmos­phere. The exper­i­ments doc­u­ment­ed in these pub­li­ca­tions showed oxy­gen tox­i­c­i­ty at 17.9 atm pro­duced esca­lat­ing symp­toms, as indi­cat­ed in this table:

  • The pres­sure at 90 feet = (1 atm + *(.445 lb/ft * 90 ft) / 14.5)) = 3.76 Atm
  • But this was Pure Oxygen, too. Normal air is 21% oxy­gen, so pure oxy­gen is 100 % / 21% is pure oxy­gen in 4.76 atmos­pheres of oxy­gen par­tial pres­sure
  • 3.76 atm * 4.76 atm = 17.9 atmos­pheres of oxy­gen

So this table, shows results for extreme­ly high oxy­gen con­cen­tra­tions. Note that even at these extreme­ly ele­vat­ed lev­els, the ear­ly pre­sen­ta­tions, less than 15 min­utes, have minor symp­toms:

  • Lip Twitching
  • Tingling of Skin
  • Vertigo
  • Hiccup
  • Nausea
