Can they make bigger ventilators?

Picture a large ventilator pump with let’s say
the capacity of 10 ventilators with the possibility
for each “branch” to have pressure controls and
oxygen controls...
If they can split ventilators, why not build multi-ventilators?
It shouldn’t be so hard to design.
It might even save some money and materials.

Ventilator splitting has been approved in NYC :

New York hospitals can now attempt to treat two coronavirus patients with a single ventilator, Gov. Andrew Cuomo announced on Thursday, a move that could help the state make better use of its scarce supply of lifesaving breathing machines as the outbreak continues to surge.

New York-Presbyterian Hospital has developed a split-ventilation protocol that has been shared with the New York State Department of Health, which quickly approved the practice.

Calling the technique “not ideal, but workable,” Cuomo said ventilator splitting may be necessary given some projections that suggest the state may need as many as 30,000 ventilators in the coming weeks.

already exist. By the time you design, test and approve a multi-patient unit you could have built a million ventilators using existing designs.

... if too many people who are qualified to set them up and monitor the patients attached to them get sick.

have one machine per “ventilator room”.
The machine could have sensors to detect and supply each patient’s pressure needed and maintain proper oxygen levels.
It would be more like one giant unit with its ventilating parts separate from one another.
This would not be like splitting a ventilator!

One medical monitor could be isolated sort of like the booth that protects personnel
from x-rays so there wouldn’t be so much worry about exposure.
Hey, my microwave can detect when the food is cooked and I have manual override.
Maybe this machine is down the road a ways, because out need is so great right now.
But this could be an efficient way for more people to have ventilation in the future.
