A family member showed 97-98 over the past few days and now shows around 94-95. Should I be concerned?
I've read that, with regard to aeration/oxygenation, ale strains usually need between 8-12 parts of oxygen per million (ppm) while lager strains require slightly higher amounts (10-15 ppm). If this is untrue or misled, please begin by correcting me!
So I have a Benzomatic oxygen tank and the Oxygenation Kit 2.0 from Northern Brewer (comes with an O2 regulator, wand w/ tip and tubing). I'm trying to figure out what rate and for how long I should oxygenate my wort, and whether I should oxygenate the wort (in the FV) pre- or post-pitch.
For rate & duration, I'd like a way to target 8 - 12ppm O2 for my ales and 10 - 15ppm O2 for lagers (if those are in fact accurate numbers).
I'm sure I could just blast it for x seconds per gallon of wort and call it a day, and I'm certainly open to answers that espouse that type of simpler protocol.
But I'm curious if there are any meters, tooling, calculations/formulas I can use as a homebrewer to hit those PPMs regardless of whether I'm doing a 1-gallon batch, 5-gallons or 10. Any ideas here?
And of course, whats the thinking here:
- Pitch yeast, then oxyenate?; or
- Rack wort to FV, oxygenate, then pitch; or
- Something else? Maybe pitch and oxygenate inline?
Hear me out, here. It's well known that the Innies have an abundance of oxygen - and a dizzying amount of dirt to grow their delicious food in. But is it their overly oxygenated atmosphere driving them insane?
After all, those squat fuckers have no problems with shit like propping up a man to be the Butcher of Anderson Station despite the belters surrendering. Innocents - not even the ones involved in the riot - died for the Inners to make their political messaging.
I theorize that their oxygen rich atmosphere is polluting their minds. If anyone here has huffed on pure O2 before (it's fun, but an expensive habit when you're living in the Belt) you know how high and euphoric you feel.
I am a an Advanced EMT and ran a call earlier today with a patient who had ALS. The family informed me any oxygen would knock out the patients respiratory drive. I was wondering if anyone knew the pathology behind this? It is very interesting and I would love to learn about it. Thanks!!
The cannula is specifically designed to prevent air embolism and reduce human error, improving patient outcome
RA'ANANA, Israel, Nov. 10, 2021 /PRNewswire/ -- Inspira Technologies OXY B.H.N. Ltd. (Nasdaq: IINN) (Nasdaq: IINNW) (the "Company" or "Inspira Technologies"), a groundbreaking respiratory support technology company, announced today it has filed a Patent Cooperation Treaty (PCT) patent application for its novel dual lumen cannula, accompanying an extracorporeal respiratory life support/saving system aimed at rebalancing patient's oxygen saturation and carbon dioxide levels. The cannula is specifically designed to prevent air embolisms and reduce human error. The patent application has been submitted to the World Intellectual Property Organization (WIPO).
The main potential advantage of Inspira Technologies' innovative dual lumen cannula lies in the user experience (i.e. physician). Dual lumen cannula insertion resembles the technique used for single lumen cannula insertion. With this technique, the physician has a convenient, efficient, well-designed work interface to speed up and simplify the cannulation process. Inspira Technologies' dual lumen cannula is designed to reduce complications such as bleeding and infection, improving patient outcomes.
Inspira Technologies' dual lumen cannula can be inserted into a large blood vessel without fluoroscopic guidance, at the patient's bedside. The cannula withdraws unsaturated blood and returns oxygen enriched blood to the patient via an extracorporeal approach. The dual lumen cannula, in comparison to single lumen cannulas, is gaining popularity among physicians due to its increased ease-of-use and reduced patient complications.

Dagi Ben-Noon, Inspira's CEO, stated: "A primary objective of the Company is to make available a novel treatment to the unmet medical need of deteriorating acute respiratory failure patients by offering a potentially cost-effective and easy-to-use extracorporeal respiratory support technology. The cannula supports this objective that is aligned with the Company's vision and mission."
So starting my first brew and I heard it's good to add oxygen with something like a leese stirrer for a little while into the fermentation. How often should I do that and for how long? Thanks ahead for the tips

Abstract
Available evidence indicates that elevated blood ketones are associated with improved hypoxic tolerance in rodents. From this perspective, we hypothesized that exogenous ketosis by oral intake of the ketone ester (R)-3-hydroxybutyl (R)-3-hydroxybutyrate (KE) may induce beneficial physiological effects during prolonged exercise in acute hypoxia. As we recently demonstrated KE to deplete blood bicarbonate, which per se may alter the physiological response to hypoxia, we evaluated the effect of KE both in the presence and absence of bicarbonate intake (BIC). Fourteen highly trained male cyclists performed a simulated cycling race (RACE) consisting of 3h intermittent cycling (IMT 180' ) followed by a 15-min time-trial (TT 15' ) and an all-out sprint at 175% of lactate threshold (SPRINT). During RACE, fraction of inspired oxygen (F i O 2 ) was gradually decreased from 18.6 to 14.5%. Before and during RACE, participants received either i) 75g ketone ester (KE), ii) 300 mg/kg body mass bicarbonate (BIC), iii) KE BIC or iv) a control drink in addition to 60g carbohydrates per h in a randomized, crossover design. KE counteracted the hypoxia-induced drop in blood (SpO 2 ) and muscle oxygenation by ~3%. In contrast, BIC decreased SpO 2 by ~2% without impacting muscle oxygenation. Performance during TT 15' and SPRINT were similar between all conditions. In conclusion, KE slightly elevated the degree of blood and muscle oxygenation during prolonged exercise in moderate hypoxia without impacting exercise performance. Our data warrant to further investigate the potential of exogenous ketosis to improve muscular and cerebral oxygenation status, and exercise tolerance in extreme hypoxia.
