My point in attempting an analogy.

By that - if you mean having 2 users hooked to the same cpap driver - sure. ūüėĀ

Think I saw some separate dual

capability on the dual setting.

If tech operating 2

I am clueless but I assumed that a ventilator would intake ambient air, filtrate and deliver to patient not re-cycle the patients air.

That is my understanding also.

Cannot recall that without more.

Hospital based ventilators are driven by compressed gas. You will have 2 lines, one is 100% oxygen, the other room air - both driven @ 50PSI. The ventilator will blend those gases to meet the settings required by the patient and determined by the clinician. The whole rig must work flawlessly 24/7. 
 

Some home based ventilators will draw from ambient room air.

So blood gas is monitored in order to determine the O2 concentration and the ventilator must have the capability to adjust and deliver the correct concentration of (hospital grade) oxygen as well as pressure. As an aside we use ABO (aviator's breathing oxygen) which is just a dryer gas to prevent freezing.

Blood gas studies assess oxygen and carbon dioxide tensions in arterial blood as well as acid base balance, carbon monoxide tension and methemoglobin and hemoglobin values. Arterial values assess lung function. Venous and mixed venous values collected simultaneously can derive a host of values regarding cardiac and hemodynamics. Add in measures of inhaled and exhaled oxygen and carbon dioxide tensions (plus their graphs) and I can determine details of lung physiology and metabolic physiology. And we can also measure cutaneous oxygen/carbon dioxide tensions continuously. 

 

O2 during flight was initiated to offset loss of oxygen at altitude and as a pressurized gas to manage¬†the bends. ¬†Honestly I cannot speak to using the gas to ‚Äėprevent freezing‚Äô.

I meant that ABO is drier to prevent freezing of the moisture in the gas

All compressed gases have water removed and are dry to keep their dispensing regulators from freezing.  Medical compressed gas lines are dry and require humidification prior to application. They’ll use dry gases in surgery most of the time. They can do that because surgery is a short term event.
 

It is sadly becoming real ugly with this virus. What a tragedy. Everyone remain vigilant and safe. Error on a very wide margin of safety.

They sent it out over our phones at ten `till eight this morning.

It is quiet out there. A lot less air traffic too, it's like after 9-11 without the fighter jets screaming by all the time.

Past week I tightened up a little and I'm also shucking my clothes after errands. Actually took off my good clothes and put on the yardwork stuff back on the other day before I went out.

Put your clothes right in the washer, 

 

If not, use a separate basket, be careful with it and clean it with alcohol or bleach, aw jeeze, just put your clothes right in the washer.

Our washer and dryer are just inside the back door, so you're right @tigerwoodKhorns that's where they went then I streak down the hall and put different non-contaminated clothes. Might just put a change of clothes on top of the dryer that's better when it's chilly in here!

 

Often been told about my grandfather who started his family in the 30s with my mom born in `35 how he came in after work. With the different bacterial and viral scourges back then, he would wash his hands, face and neck before coming to the dinner table. Gargled with salt water too, he did not even get a cold during the winters back then. Working outside for the power company with creosote on the power poles obviously he changed into clean clothes. Heck from the sound of what I just wrote I'm surprised if he didn't actually just shower before gathering with his family!

We here, as often in the world, we have great doctors, scientific and professor Raoult, but services wars are stronger than men: too bad


For those who can read French (or use an online translator)

Note: for your information, Professor Raoult is the researcher who said on February 24, 2020 to have discovered that chloroquine treats Covid 19 and that clinical trials must be done quickly.
