Bill. Show them the door until they have decent kit ready!
After all, as we have seen, their website suggests that this is not only already the case, but has been for a number of years!
Strange (?) though that the infamous "Patientline" rears it's head again!

Does it monitor (collect data) on anaesthetic content and gas flows
etc. (I'm presuming that it does, if it's to be of any real use)? How does it do that, I wonder? RS-232 ... to where (what)?
Or is it just
leeching data from whatever "proper" patient monitor(s) happen to be in play?
