Medical ventilator is a machine used in a hospital or similar setting to help a person breathe. They are used with severely ill patients who are sedated or in a coma. They are typically constructed of various sub-assemblies, such as a pump, and control electronics (which control breath frequency and volume, based on measurements and settings). When one sub-assembly fails, others may still be good. It is possible to connect working sub-assemblies from two compatible broken machines to make one working machine.
Some manufacturers use Digital rights management controls, to control whether they will allow a repaired device to operate. Unlocking the DRM may also require internet access, making repair difficult in emergencies, or where internet access is difficult.
Consumer-impact summary
[edit | edit source]- Loss of life, since fewer ventilators were available at a time of extreme need.
- Increased cost of medical care (ventilators sitting idle awaiting repair, increased cost of repair).
- Increased e-waste.
Incidents
