It took my legs a few minutes to warm up this morning, but glad to report that long morning walks remain easy, in contrast to later in the day. #Totnes is waking up beautifully ☀️
5 miles walked this morning, with no adverse effects. Then strimmed & mowed a lawn. Great to not be worried about my heart and lungs as I got a real workout from the gardening. However, I'm mindful of the warnings of some with #LongCovid that I should continue to pace myself.

1) Hypoxemia --> low blood O2 levels.
Hypoxia --> low tissue oxygenation wrt demand
Types of hypoxia
1. Hypoxemic
2. Stagnant
3. Histotoxic
4. Anemic
5. O2 affinity hypoxia

2) The problem arises if you define O2 content of blood purely as PaO2 or as PaO2+ oxyHb saturation --> for this is the total O2 content of blood.
If we eliminate oxyHb, O2 content of blood becomes less meaningful since the lion's share of O2 is carried by hemoglobin!

3) If you consider oxyHb + PaO2 in total the anemic and O2 affinity forms of hypoxia must necessarily be a cause of hypoxemic hypoxia --> since anemia (reduced Hb) or increased O2 affinity --> cause HYPOXEMIA!

Spent more time in the garden today. Insect populations are booming! A bit of sunshine really helps to lift the spirits.

Had a run of 3 good days, but just tried doing *some* of the things my lungs had allowed me to do over the weekend & over-did it by fixing the ball-cock in the toilet cistern! Lowered my guard; lungs are tight again (first time in 10 days) & I'm lightheaded. #PulmonaryEmbolism
I want to talk about #LongCovid & #hypoxia & how my experience of it now is *drastically*, even *dangerously* different to what prior lung issues taught me.
I didn't plan to do this thread and I'm not thinking clearly atm, but it's important, so I'm going to give it a go.

Background: I was born prematurely & before synthetic surfactant, so I have asthma and temperamental lungs in general. I also have an extensive history of pneumonias that try to kill me (as in ICU stays). So I've had 40 years of knowing how to handle not being able to breathe.
I knew about happy hypoxia. I knew how, when, and what to do about it when my judgment about whether I was alright started to slip, and I knew that that's often the first thing to go when you're hypoxic - *first*, you feel... off. Unquantifiably off. It's easy to miss it.
We are extremely happy to present our lab’s first #preprint! Together with @teamstembryo we identify #hypoxia as a major microenvironmental factor that governs ES cell lineage commitment.

Have you ever wondered how environmental factors such as #hypoxia together with intrinsic cellular regulators shape stem cell identity and differentiation capacity? We have (a lot!). But wait a minute you say, isn’t oxygen essential for mammalian life? (2/11)
Of course it is! But… before placentation, the embryo develops in an increasingly hypoxic environment where oxygen tension is as low as 1.5%. But what’s the physiological relevance? @odedrechavi

An oxygen saturation of below 95% is an indicator of a need to seek further Rx.. if the #COVID19 Px is quarantined at home.. 2/n

Oxygen saturation levels easily measurable using a #pulseoximeter .. easily available at Pharmacies. In fact, currently it's a standard item for those who are under home quarantine for #COVID19 ..

You’ve probably seen or heard about the #PlandemicDocumentary video. It reaches many conclusions that have zero scientific support and are dangerous because they could harm your health. Here are rebuttals and references to just a few of the false claims. A thread. (1/x)
False claim #1: The novel #coronavirus was lab-made.
Truth: Genetic science allows us to understand how and when viruses emerge. Analyses by trusted scientists clearly demonstrates that the virus occurred naturally. (2/x)

I'd like to point out that while the resolution of a #chronicillness was striking, what is more striking is the rapid descent into Wernicke's in a hospitalized 90 yo woman - a descent so striking that she went into respiratory distress necessitating a #ventilator. 1/
Upon giving #IVthiamine per a #wernickesprotocol at 200mg 3X p/d she woke up, after just 2 days of thiamine treatment, and the ventilator was removed. What could this tell us about the use of thiamine in #COVID19? Perhaps the cluster symptoms we see are really just a variation 2/
thiamine deficiency - one that is being missed by practitioners everywhere because we're not looking at the #mitochondria for answers. 3/
I want to talk about 2 papers that highlight the role of mitochondria in what are likely the progression of symptoms assoc with #COVID19. Note these papers are not about #covid but highlight important pathways. 1/
1st paper - Intracellular ATP is req. 4 #mitochondrial #apoptotic pathways rat #cardiac #myocytes ncbi.nlm.nih.gov/pubmed/12909326 2/
Key findings: apoptosis and necrosis are part of the same pathway, initiated by same mito sequences but are distinguished by time and severity, where the delimiting factor is available intracellular #ATP. 3/

Patients in respiratory distress affected with #COVID19 arrive with up to severe #hypoxia but usually normocapnia. Therefore no respiratory distress nor hyperventilation

Therefore Emergency doctors decide to admit otherwise healthy patients with oxygen saturation below 94% (young patient) or 90-94% (older patient or with chronic lung conditions). For those not falling below the threshold they perform the 40 steps test

Took me a while, but in response to @AmyPearsonMD tweet of my talk last week @uihealthcare, a thread on ⬆️FiO2 and #SSI.

Whether intraoperative high inspired oxygen is beneficial is not a settled question.* This thread explains why I routinely use it unless there is a contraindication. bit.ly/2gexBIz
*The evidence that it is NOT harmful is overwhelming.
*The evidence that it is NOT harmful is overwhelming.
Impetus to investigate high-inspired O2 grew out of in vitro, animal, human volunteer, & patient studies (1960s-90s): wound hypoxia associated with⬆️#SSI & peripheral vasoconstriction resulting from SNS activation is common source of wound hypoxia. bit.ly/2H9SlfS
