Common household appliance points to better path for ventilating multiple patients with single machine

With further testing, gas appliance pressure regulators could provide each patient with their own personalized input pressures

July 7, 2020

While the FDA has approved adaptors to split ventilator tubing, this provides the same inspiratory pressure to both patients, and supporting multiple COVID-19 patients with a single ventilator requires the ability to supply different pressures to each patient that can be titrated on a daily basis.
Gas appliance pressure regulators are common household instrument. This one from Maxitrol was used in the new split-ventilator configuration developed by the Bay Area team of physicians and engineers.
