Here is an article from Respiratory Therapy Magazine in 2016 highlighting a study where positive pressure bubble helmets reduced intubation rates of ARDS patients.

The intubation rate was 61.5% for the face mask group and 18.2% for the helmet group. The median number of ventilator-free days was significantly higher in the helmet group (28 vs 12.5). At 90 days, 15 patients (34%) in the helmet group died compared with 22 patients (56%) in the face mask group. Adverse events included three interface-related skin ulcers for each group.

This is the same style seen in the Italian hospitals. If the results are being replicated, an open source bubble helmet seems to be an appreciable public health goal.
