I think it needs to be understood that, in many parts of the world, OEM training or support is simply not available or at best beyond the funding available. Given that, ask yourself this. If you had a family member in one of those areas who needed a life saving operation would you prefer....
A/ an anaesthetic machine that had been serviced by a (non OEM trained) biomed tech with a copy of the manual or..
B/ no anaesthetic machine at all
In many parts of the world, these are the only two choices available
I, for one, will continue to provide whatever info/support I can to those who need it and, having seen the way things can be in other countries, I would encourage others to do the same.
