@dch rough afternoon in the CRA dev room.

@aki that is one of the highest values I’ve ever seen 😮 apart from airline flights

@dch under 700 is a dream value... At work I open the window above 800ppm, usual rooms with all these people barely drop below 1200.

I'll fire up my CO2 sensor... Brb

@dch

Room H.2215

Carbon dioxide concentration : 1474 ppm
Environment temperature : 22.88 C
Relative humidity : 47.74 RH

unofficial, probably not correct values. But if I go outside, the sensor drops below 500ppm...

@ligasser I hope you stay safe

@dch thanks... It seems I'm lucky to have had COVID even after vaccination, but never really felt it...

Seeing how it treats others, I'm happy :)

@dch Can I ask which kinds of medication and treatments you're using?
I'm dealing with ME/CFS and so far haven't found anything that works...

@dch@bsd.network · 3 weeks ago

@82mhz you totally can. If you want to discuss more feel free to chat next week.

Daily
- 2mg low dose naltrexone
- 1mg aripiprazol
- 4mg Intuniv
- NAC+
- metformin 500mg
Not daily
- infra red therapy
- eliminating carbs from diet (keto)
- forskolin
- CoQ10
- vitamin B C D
- 5HTP 200mg

Pacing!
low intensity exercise a couple of times a week.

I started off on Aripiprazol and had some improvement, then tweaked with naltrexone, and in 2025 started Intuniv which has been the 🔑 and game changer. I’d guess I am about 70% recovered now since this time last year.

@dch There is no data which supports "< 700 ppm CO_2 indoors is probably safe". It's a bit less dangerous, yes, but calling it "safe" is unfounded.

@foremostarchwiz @dch Indeed.

The Sasebo Chuo Hospital study estimated a 30% chance of infection at 600ppm with no mask after 15 minutes in the same room with an infected person (simplified):

(They thought they could keep Reff for the entire hospital under 1.0 with CO2 <540ppm, but that's a slightly longer story.)

SARS-CoV-2 airborne infection probability estimated by using indoor carbon dioxide - Environmental Science and Pollution Research

Airborne transmission is one of the main routes of SARS-CoV-2 spread. It is important to determine the circumstances under which the risk of airborne transmission is increased as well as the effective strategy to reduce such risk. This study aimed to develop a modified version of the Wells-Riley model with indoor CO2 to estimate the probability of airborne transmission of SARS-CoV-2 Omicron strains with a CO2 monitor and to evaluate the validity of this model in actual clinical practices. We used the model in three suspected cases of airborne transmission presented to our hospital to confirm its validity. Next, we estimated the required indoor CO2 concentration at which R0 does not exceed 1 based on the model. The estimated R0 (R0, basic reproduction number) based on the model in each case were 3.19 in three out of five infected patients in an outpatient room, 2.00 in two out of three infected patients in the ward, and 0.191 in none of the five infected patients in another outpatient room. This indicated that our model can estimate R0 with an acceptable accuracy. In a typical outpatient setting, the required indoor CO2 concentration at which R0 does not exceed 1 is below 620 ppm with no mask, 1000 ppm with a surgical mask and 16000 ppm with an N95 mask. In a typical inpatient setting, on the other hand, the required indoor CO2 concentration is below 540 ppm with no mask, 770 ppm with a surgical mask, and 8200 ppm with an N95 mask. These findings facilitate the establishment of a strategy for preventing airborne transmission in hospitals. This study is unique in that it suggests the development of an airborne transmission model with indoor CO2 and application of the model to actual clinical practice. Organizations and individuals can efficiently recognize the risk of SARS-CoV-2 airborne transmission in a room and thus take preventive measures such as maintaining good ventilation, wearing masks, or shortening the exposure time to an infected individual by simply using a CO2 monitor.

@mediaevalfishsandwich @foremostarchwiz cool to see some studies done on this. Thanks!

dch :flantifa: :flan_hacker:

@dch@bsd.network · 3 weeks ago

@foremostarchwiz True; this is my experimentally derived value. Since following this I’ve not gotten infected at events with close contact and spreaders.

@dch what medication are you using?

I was doing low dose naltrexone for the last few years but stopped it cold turkey over the holiday season because it was impacting my sleep too much. I definitely am noticing a difference (better sleep, worse brain) without it.

I also am on zepbound which has been beneficial. It's helped reduce inflammation for me and I've lost a bit of weight which is a bonus. I think without the zepbound, it would have been disastrous to come off the naltrexone.

The specialists I've been seeing at Stanford have not been particularly helpful with suggesting newer/better treatments 😣
