With the face shield V8 at a place where we are getting evaluation. I'm going to start putting information here for a ventilator splitter design.

A quick research has come up with a fact that ventilators are NOT supposed to be used at a ratio of 1:Many. There are things to consider such as different lung capacity, different illnesses each patient may have so contamination and etc. These are under normal circumstances.

The thing to focus on here is how ventilators can be used under an emergency situation. If all patients have roughly the same lung capacity, the tubing to the patients managed with the same run length, and most importantly the cross contamination aspect. If all patients on the ventilator has the same illness this may not be an issue under an emergency situation. This type of usage is outside of the specification of how the manufacture listed and also medical training so we have to consider the circumstances here. Save 1 person...or multiple and risk cross contamination.

It's also noted that patients needs to be paralyzed for this to work.

There is a clear video from Dr. Charlene Irwin Babcock talking about the above points.

It's obvious that this approach has risks. The ideal situation is 1 ventilator per person, but we know that not all hospitals have enough ventilators as they are expensive.

---------------------------------

With this information, we need to first connect with respiratory therapist and emergency doctors to really understand the scope of this and see if the approach is right. It may not be as simple of a process to just make a splitter.

However, there could be a place for a smart splitter system with sensors and controls to properly measure and deliver flow and limit cross contamination. This would probably be the right angle to approach and tackling this idea.

Last note, it seems the international standard for ventilator breathing circuits is 22mm.
