You forgot the Respiratory Therapists.

As a former respiratory therapist I understand you concern about a project like this. I doubt anything beyond a CPAP machine is helpful for home care without risking a ventilator lung injury which is often characterized as the same lung pathology that COVID-19 creates in the acute respiratory cases.

That said, at home you could help at home patients relieve some symptoms until proper medical attention is available by doing positive breath holding exercises and chest percussion therapy to recruit more alveolar activity.
