The Procurator Fical is the Coroner in Scotland and it was him that sent in the CID to collect the device. We had already taken a note of the settings and sealed it in bag.
Providing you have been trained to service the device and service it to the manufactures spec and record the servicing with any necessary results, there should be no problem.
Problems may arise where you don't follow the service spec or use copy parts.
Everybody has the right to report incidents directly to MHRA etc, this is especially important when you find faults in a batch of breathing circuits. The MHRA needs to progress this sort of thing quickly as this could affect lots of hospitals.
I can fully sympathise with the guy with ventilator. I was called in here a few years ago to be greeted with "Your defib killed my patient". After talking to the doctor who attended the patient, the defib discharged as expected. It was only the fact that they couldn't get a readable ECG (just lots of lines) and the same happened with a monitor. A demand to be shown the ECG electrodes that had been used, involved the nurse rummaging in the bin. You've gussed it! Bone dry and crystalised. And I had an apology!
