In Wuhan they ran out of hospital capacity and sent people home. People bought vents to administer to their relatives at home without medical supervision.

You need to dispose yourself of the false assumption that people who need vets would even be able to get through the door at an ICU during a serious pandemic.

I hope those folks, well-intentioned as they may have been, did not deprive actual hospitals from getting the equipment that they needed by doing this.

Could you please provide the reference? The ventilation procedure is very difficult and dangerous to carry out, and I've seen people confusing oxygen mask and related devices (as treatment for mild syndromes) with ventilators.

considering the cost of ventilators I doubt that people in Wuhan were using them in any numbers likely to be noted, thus yes, oxygen masks and related devices most probably.
