Hello, I purchased a second hand Resmed S7 Elite CPAP machine recently from an American supplier and after a few weeks it arrived in the UK - the machine is great and has less than 30 hours use on it BUT it came without either a User's Manual or Clinician's Manual and minus the important Pressure Sensor Adapter. Because of these shortcomings I am unable to use it yet and wonder if anyone can help point me in the right direction - I have no trouble with the American power cable. Perhaps somebody who is familiar with this machine can help me, I need to change the pressure which I cannot identify but it is high and although the machine starts it shuts down after a few seconds presumably because of the missing Pressure Sensor Adapter. I usually use a Resprionics Auto and my average pressure (smart card) is 6.5 which is low but life saving. I would appreciate any help.

Probably not what you want to hear, but you may be out of luck. A quick search for parts for Resmed S7 cpap showed 3200 hits. However, the user manual states that there are no user serviceable parts inside. Repairs and internal servicing should only be performed by an authorized service agent.

So, I figure it is unlikely that you will find the parts anywhere on the internet and if you did there would be no instructions. Further, you would need to have professional help in checking that the pressure was indeed correct. So my recommendation would be to find a Resmed service agent in your country and have them set it up for your prescription. Probably cheaper than a new machine, I would think, but you would need to ask them for an estimate to see if it was worth it. The technology has come a long way since the s7.

I also would be suspectious of an American vendor that even sold you a second hand CPAP.

American regulations through our FDA prohibit the sale of used durable medical equipment such as a CPAP.

Looks like the vendor may have been getting around more than a missing sensor selling a unit to you in the UK.

Thank you both for your responses, I think I have wasted my money and I have put it out of sight in the garage in case I am tempted to spend more money on what is really outdated technology. Thanks again. Eric

I am not familiar with the Pressure Sensor Adapter. But I do know that my S7 Spirit shuts down after a few seconds of non-use
(gross leaking). Have sent you an Email which may help you find help.
