For SpO2 levels - portable oxygen vs HBOT during acute COVID, with a twist. My data point contributions. 86% with 4L/min portable O2. In mild HBOT, not even 1/2 way to 1.3 atm, look at the change in SpO2 & HR - all at rest🧵
2/ Here’s the twist: even KN95 masked while in HBOT and not even 1/2way to 1.3 atm (very low because sinus & ear pressure) is superior to portable oxygen alone, just 11 minutes in HBOT. Why masked, you ask? 2 reasons: 1) exhaling active infectious COVID will release into the room
3/ when I depressurize and release the air. I wanted to see if I could prevent accumulation of viral airborne particles in KN95 & still get benefit, and 2) to check the hunch that wearing a mask is not what drops O2. Also, comparing portable O2 alone vs added pressure to dissolve
4/ oxygen into blood even at very low pressure makes a quantitative measurable difference. Let’s compare: 1) without, 2) with portable O2 4L/min, 3) mHBOT halfway to 1.3 atm Notable severity of symptom reduction in HBOT during acute COVID even w lower pressure superior to O2.
5/ Early studies with sham (lower, but still pressure) that concluded no benefit to HBOT because there was no significant difference between both conditions, both improved. I’ve always wondered if the study failed to ask at what pressure is benefit noted? pubmed.ncbi.nlm.nih.gov/25401463/
