Powered Air-Purifying Respirators (PAPRs) are effective pieces of Personal Protective Equipment (PPE) that could be helpful to caregivers. PAPRs will also be in extremely short supply and are much less risky and less controversial than a DIY ventilator. You also may be able to save many more lives by building a PAPR that protects a caregiver than a mediocre ventilator for one patient.
