Various people on here talking about whether the machine should be re-designed obviously haven't watched the video clip attached to the news story.

The on/off switch that the nurse used to turn the machine off was a large switch positioned on its own on the top of the machine, clearly seperate from any other switches.

I can only presume that either:

a) The nurse MEANT to turn the machine off and used the on/off switch deliberately. Perhaps this was because she didn't think it needed to be on all the time, or something. This is a serious training and competence issue, to which a re-design of the machine is clearly not the answer.

b) She was really, really, really stupid. So stupid that a re-design of the machine would not help.

Either way, the machine does not need to be re-designed.

What needs to happen is:

a) If the nurse HAD been properly trained to use the machine and turned it off due to serious negligence on her part, action needs to be taken against her. She should be prevented from working with vulnerable people ever again, and possible subject to prosecution - if for no other reason than to demonstrate the seriousness of her negligence and stand as an example to other health professionals.

b) If the nurse had NOT been properly trained in the use of the machine, the firm which employs her should have their contract to provide this service terminated, and if possible they should be prosecuted.
