From Dr S' thread
Venous congestion, particularly when caused by tricuspid regurgitation, may produce venous pulsations which may produce low readings with ear probes.http://www.nda.ox.ac.uk/wfsa/html/u05/u05_003.htmhttp://www.oximeter.org/pulseox/lim_venous.htmhttp://www.springerlink.com/content/q387524121462516/
Central venous pulsations associated with a falsely low oxygen saturation measured by pulse oximetry
But would the flow effects of CCSVI be comparable to that of central venous pulsations or tricuspid heart regurgitation, enough to register and interfere wth an ear oximeter?

Thank you so much Cece. Once again you have given soo much to the think tank.
After reading these articles I am of the opinion that there is grey areas with results. The bottom line is that there are circumstances like CCSVI that cause readings that are of concern!
Doubled checking the equipment and fitting seems to still indicate that there is reason for further assessment of what is happening for the patient, IMO as always!
