This section lists the more common questions our customers have with regards to the moorVMS-PRES. If you have a question you would like answered that does not appear below then please email us. We are happy to help!

Q. What is the fastest way to deflate the cuff?
A. You can set the moorVMS-PRES to automatically deflate at MAXIMUM rate, or we can supply a cuff with a manual deflation valve ideally suited to the Post Occlusive Reactive Hyperaemia protocol - please ask for further details.

Q. Can I change the position of the green markers in the review trace window?
A. Yes - double click on the marker you wish to move and type in the time position you wish to move it to.

Q. Can I use the moorVMS-PRES with other flow detectors?
A. Yes. moorVMS-PRES can operate in stand alone mode as a cuff control system to reliably automate inflation/ deflation protocols. Standard built in protocols can be edited and operated from the front panel (without a PC or additional equipment). Analogue outputs are provided to integrate the pressure signal with your own device.

Q. How can I use the moorVMS-PC software for analysis?
A. All moorVMS modules link to your PC through USB connections. This allows automation of the pressure protocol with analysis markers inserted into the trace. This allows the software to calculate and report on the various parameters associated with the trace. You can choose which parameters you want calculated and how!
