Usage scenarios
I talked with my friend who works at ICU. There are two kinds of patients:
- ones that can breathe normally but have difficulties, they just need an oxygen mask. No ventilator is needed.
- ones that cannot breathe and/or are sedated. The mask won't work for most of them because they cannot keep the right jaw position. In most cases, only invasive ventilation will work. They often breathe with pure oxygen using a ventilator.
I'm just curious about scenarios of home usage of such devices, without a need for a doctor and oxygen supply. What needs to be taken into account is the compatibility of plastics with high oxygen concentration. Most of them will break apart quickly because oxygen is very reactive.
