The Government plan to increase it by at least 2000 units in the shorter possible time.
New hospitals have been built or converted, but there is a great shortage of doctors, nurses and other medical professonal.
Now, luckily, the numbers are going down and hospitals have free intensive care units.
2000 units  will maybe suffice (but I read that some units are being imported or donated by other countries).

40% increase over several months is a complete fail in regards of what's actually needed in current situation. Which means this approach does not work efficiently.

Bud:
There comes a blow to delusional wannabe ventilator engineers trying to save the world.

I don't  know if another approach could be more efficient.
How could you build more units from a single certified factory,  respecting  all the requirement imposed by the certification process?
Maybe this should have been done many years ago, when the WHO advised every country to prepare for a pandemic but most countries did not.
Build a lot of ventilators, a lot of intensive care units, increase spending on medical staff, pay them more so they will not study here (in public universities, funded with taxpayer's money) than leave the country for better paying places.
In Milan they were capable of buliding a new hospital in less than two weeks, but it is not fully used.
There are not enought doctors and nurses, even with the help of professionals that came from Albania , Russia and other eastern countries.
Now the situation (at least here in Italy) seems to be better.
When this will end, a lot of things must be changed, and not only in Italy...

But should we do just anything just because we are in a hurry? I don't think so. It's usually the worst approach possible.

It really depends how exceptional the circumstances are.
Also, how you focus on the risks.  The risk to one person or the risk to a group of people.

If you go on the risks for any *individual* patient in extreme need of a ventilator. 
You might say
  "We have tested this completely non-certified ventilator and it seems to work, but the unit may kill the patient if it's defective or malfunctions
You can also say
   "There is a tiny chance the patient might pull through without it".
Therefore we should not use it as it might cause harm that would otherwise not have occurred.


If you go on the risks of a group of people all in extreme need of a ventilator.
You might say
  "We have tested this completely non-certified ventilator and it seems to work, but some units may kill patients if they're defective or malfunction"
And then, given the volume of people currently dying each day through lack of any ventilators.
  "When compared with not using them at all, this non-certified ventilator should save more lives than it ends through defects or malfunctions."
Therefore we should use it since it will be better for the group overall.
