[arrl-odv:30006] Amateur Construction of Ventilators
I have been contacted by Frederick M. Barken, M. D. WA2BLE, an active amateur and retired physician located in the Western NY Section of the Atlantic Division. As you are aware NY is currently the epic center of the outbreak. The good doctor has suggests that Amateur Radio has the potential to make a substantial contribution to in the saving of lives by producing ventilators in volume. Please review the below series of emails and offer comments on whether this concept is feasible/practicable and how to best jump start this project. This envisioned project would similar to what Micky has shared on a larger scale as I understand it. It is awesome that folks are working toward common goals.

Yes, I had given thought to all the same considerations. As far as distribution goes, that could be through contacting state health departments. They know exactly how many ventilator units there are in each hospital. I know in NY the governor is calling for 30,000 units! I could imagine the state of NY offering to compensate individuals for their outlay, or setting up some sort of fast-tracked grant, perhaps assigned to ARRL for fair distribution. Retired hams, sheltering in place and able to buy the kit, might just do it as a donation. Delivery of units could be by Fedex, with hospitals paying the shipping through their budgets. I wouldn't count on the need for units diminishing in spring. So far there is no sign that this virus behaves like seasonal influenza, and the toll will be horrible if we don't meet the need. The best guess I have read is that this will continue to come in rolling waves throughout the country. The unit would have to be of the utmost simplest design to keep down parts cost and assembly time. One or more parts suppliers, commonly used by hams, would just throw the parts in a box and ship.There would have to be a very simple manual, both for assembly and for operation. There also would have to be some sort of on-line registration to receive a kit and confirm when assembled. Issues of privacy (HIPAA), medical and product liability, and patent protection are rapidly melting away in the face of a national emergency. We essentially would be operating as Good Samaritans.

Here in NY State the Governor estimates that we will need some 30,000 ventilators to support victims of COVID-19 infection. There is simply no way that is going to happen if supplied only from commercial sources. Is it possible, given a bare-bones design, that a significant number of devices could be crowd-sourced by a large number of hams and hobbyists doing the assembly? A ventilator is simply an air pump with just a few variables to control: the tidal volume (how much air moves with each inspiration), the ventilatory rate (how many cycles per minute), the % oxygen in the inspired air, and something called positive end expiratory pressure (PEEP) which leaves the airway expanded in exhalation, just like with a CPAP machine or the mask that is worn by a fighter pilot at high altitude. PEEP is adjustable, but typically is about 5mm Hg. The control circuitry for this should be very simple. The device would require standardized fittings to work with the hoses found in hospitals and set up by respiratory technicians. The machine doesn't have to be pretty. Anything that could be done can only save lives. If ARRL could take the lead on this, publishing on line the assembly instructions, perhaps a parts supplier could scramble to create a kit to be sent to thousands of home brewers. They could either donate the device to their local hospitals or there could be some sort of organized distribution system set in place. Would you please give this idea some consideration?

The UF project is pretty far along. This information was updated yesterday and can be freely distributed. It IS designed so that it can be manufactured commercially or by individuals.

Tom,
Thank you for your quick reply. Yes, I had given thought to all the same considerations.
As far as distribution goes, that could be through contacting state health departments. They know exactly how many ventilator units there are in each hospital.
I know in NY the governor is calling for 30,000 units! I could imagine the state of NY offering to compensate individuals for their outlay, or setting up some sort of fast-tracked grant, perhaps assigned to ARRL for fair distribution.
Retired hams, sheltering in place and able to buy the kit, might just do it as a donation. Delivery of units could be by Fedex, with hospitals paying the shipping through their budgets.
I wouldn't count on the need for units diminishing in spring. So far there is no sign that this virus behaves like seasonal influenza, and the toll will be horrible if we don't meet the need.
The best guess I have read is that this will continue to come in rolling waves throughout the country.
The unit would have to be of the utmost simplest design to keep down parts cost and assembly time. One or more parts suppliers, commonly used by hams, would just throw the parts in a box and ship.There would have to be a very simple manual, both for assembly and for operation.
There also would have to be some sort of on-line registration to receive a kit and confirm when assembled.
Issues of privacy (HIPAA), medical and product liability, and patent protection are rapidly melting away in the face of a national emergency. We essentially would be operating as Good Samaritans.
Last night I also reached out to Bryan Bergeron editor-in-chief at Nuts & Volts, and he is looking into the feasibility of such an endeavor. I include him on this email in the hope of all working together

I thank you all for your consideration and am happy to help in any way I can.

There is simply no way that is going to happen if supplied only from commercial sources. Is it possible, given a bare-bones design, that a significant number of devices could be crowd-sourced by a large number of hams and hobbyists doing the assembly? A ventilator is simply an air pump with just a few variables to control: the tidal volume (how much air moves with each inspiration), the ventilatory rate (how many cycles per minute), the % oxygen in the inspired air, and something called positive end expiratory pressure (PEEP) which leaves the airway expanded in exhalation, just like with a CPAP machine or the mask that is worn by a fighter pilot at high altitude. PEEP is adjustable, but typically is about 5mm Hg. The control circuitry for this should be very simple. The device would require standardized fittings to work with the hoses found in hospitals and set up by respiratory technicians The machine doesn't have to be pretty. Anything that could be done can only save lives. If ARRL could take the lead on this, publishing on line the assembly instructions, perhaps a parts supplier could scramble to create a kit to be sent to thousands of home brewers. They could either donate the device to their local hospitals or there could be some sort of organized distribution system set in place. Would you please give this idea some consideration? Thank you very much. Fred, WA2BLE ___________________________________ Frederick M. Barken, M.
