We should be careful here. Smarts and creativity go a long way, but they're not a substitute for the years of training and experience of health-care professionals. Other commenters have mentioned delivering mixtures of gas as a requirement. I'll add sterilizing the equipment between uses. It's true that the durable medical equipment (DME) industry is ripe for disruption. But that disruption isn't going to come from cheap stripped-down equipment, even if that equipment has stunningly wonderful software in it. DME industry disruption will come from figuring out how to break the innovation-restricting stranglehold of Group Purchasing Organizations on health care supply chains. That's harder to pull off than quick-turn prototypes. What's needed is market disintermediation. That's a political and financial challenge, not a gadget-creation challenge. Somebody once said to me, "software is the most complex thing ever invented." But that can't be right: look at a modern airplane. It has software in it, but it has plenty of other complexity. DME is the same way. Creativity like Dr. Daily's is great. Really great. But it alone doesn't solve hard problems. If we software types claim it does, we're setting people up for disappointment.
