To tie in with your attempt to get back to TV's, the Safersleep rep said that the uint they brought in was essentially a modified "Pateintline" unit with a RS-232 port on the back. the device they brought in bore no resemblance whatever to the one shown on the website. It looked like a battered monitor with an aluminium plate fitted on the back. I fell into the trap of saying "where is the PC then" the rep pointed out that it was built-it to the monitor- ooops. The eqipment was brought in for a demo but if they come back for a proper trial I hope the anaesthetists insist that they bring in the "proper" devcie which hopefully will be compliant. If I were leading the trial I would send them away without even looking at the system.
