Does anyone else find it amazing (in a bad way) how fast this thing spread around the world? I mean a few short months ago a single person got it and now it reaches to every corner of earth. That part of it mind boggling and I guess is just due to our global economy and travel systems.

My wife uses a CPAP and I really doubt that hospitals will use one in a busy Intensive Care Unit. With COVID, the lungs lose their ability to exchange oxygen to the bloodstream, regardless if they can breath on their own. Patients have had to have their blood oxygenated in a machine outside of the body because the lungs stop working.

What Is a BPAP? | Saint Luke's Health System
Thanks for sharing that info. I have used a CPAP since 2004 (a real life saver in my experience) but I never took the time to understand the advantage of the BPAP over the CPAP before your post. It seems like starting early on with a BPAP especially with Oxygen if required might help prevent requiring a true ventilator later in some cases.

Vitamin D Supplementation in Mechanically Ventilated Patients in the Medical Intensive Care Unit
Results
Among the 610 included patients, 281 received VITD, and 329 did not. There were no differences in outcomes between these groups. However, we did find significantly more ventilator‐free days (21.0±2.6 [adjusted mean days±standard error] vs 17.6±2.4, P=0.04) and ICU‐free days (18.5±2.5 vs 16.3±2.3, P=0.03) in patients who were taking VITD prior to admission (n=91) vs those who were not (n=519). No patients who were taking VITD before admission died vs 34.5% of those who were not (estimated odds ratio=4.9×10−7, 95% CI=3.1×10−7 to 7.5×10−7, P<0.0001).
This was mentioned in my reading over the past 6 weeks but I never did drill down on it. It seems like vitamin D started when put on a ventilator did not really help the outcome but Vitamin D did improve patient outcomes IF the patient was already taking enough Vitamin D3 prior to needing a ventilator.
In 2013 my Vit D level was 22 ng but I was slow to follow my doctor's advice to get it up until I started researching it. I have been at a level of 155+ ng for three years now and I recently decided to get it worked down to 100 ng last month but with all the talk about COVID-19 I decided to do that later. The problem with Vit D levels there are no studies as to the best Vit D levels so we are stuck working with anecdotal info. For my n=1 self studies I try to determine a safe level from anecdotal cases and stay below that level during my eval.

My point was that CPAP/BiPAP can meet the needs of SOME patients who would otherwise need a ventilator. If keeping alveoli open increases oxygenation sufficiently in a patient who is not too tired to breathe, then a ventilator which forces air into the lung isn’t needed. In pediatrics we often get away with CPAP rather than mechanical ventilation and thereby avoid extra risk of nosocomial infection related to the endotracheal tube. For the sickest patients, mechanical ventilation will still be necessary.

Watch the 2011 film 'Contagion' it is eerily close+ to what we are experiencing...and gives some insight...
The virus in the film even originates from bats...It is well acted with a good cast
With just a bit of extreme (I hope) in the film...what we are experiencing is "life imitating art"...

bdog it is like totally UNREAL in my mind. There is much discussion and BS speculation out there today but in time we should have some scientific data. As a Simple Wild Donkey Guess (SWAG method) I think we will find more than one way of transmission perhaps. We do know in the USA the red dots on the maps started around international airports so your global economy and travel systems thought seems to be on target currently.

Oxygenating blood outside the body or lung is called extracorporeal membrane oxygenation or ECMO. That’s WAY more complicated than mechanical ventilation and to my knowledge hasn’t been used for any Covid-19 patients.
Both mechanical ventilation (ventilator) and CPAP/BiPAP use the patient’s own lung to oxygenate the blood. The only real difference is that a ventilator breathes for you and can be set to provide pressures that a sick patient could not generate or sustain themselves while the CPAP BiPAP devices just cleverly maintain some back pressure so that the alveoli, where oxygenation occurs, don’t collapse when you exhale. If alveoli collapse it takes more work to open them again and this interferes with the exchange of oxygen and carbon dioxide.

No not really . all the signs were there.
And as you pointed out the ability to travel in hours to most parts of the world.
The Ro was and has been thought to be at least 3 which means it was very likely to spread faster than the Spanish flu did. logarithmic /exponential growth, Not linear...
It has Camellian Properties= people able to spread while showing no signs/ several different symptoms also to no symptoms of being infected
Long incubation , If people showed signs quicker it would be easier to control and track.
The Virus seems to be more deadly than chinese officials said. From the early reports leaked from China
The leaked hospital vids and the Conversation with the Funeral director sure seemed to point to a higher death rate and communicability than what has been admitted to.
There are things that i find amazing
But will save that for the Politics forum.

No question air travel has sped up the pandemic but remember that travel by ocean was all that was needed for the “Spanish Flu” to travel from the USA to the rest of the world and that horses and sailing ships carried the plague back in the ?1400’s.

Yes it is mind boggling! :confused2: There are 2 basic reasons 1.) Seven billion humans covering the planet 2.) Jets to quickly fly those humans around the planet.
