I had a bad experience recently when I went to get tested for PFO. They tested me for the wrong thing - PDA, and then agreed to redo the test. This was due to an incompetant doctor and lab technician that didn't really know what a PFO was. I went back recently and told them the exact procedure that they should have followed which was inject saline that has been shaken up in air several times into a vein. It is rapidly injected, first while breathing normally. the procedure is then repeated six times, while exhaling hard agains a closed glottis. this raises the pressure in the right atrium and will cause a jet of bubbles to go from right to left across a PFO. THEY DIDN"T TO THIS What they did when repeating the test did not involve the injection of any saline. They performed the 2D echo on me while I held my breath, but pushed or contracted like taking a crap. She said that doing this would raise the pressure in the attrium and detect a PFO. My question is this: Is that enough of a test, or do I have to do the procedure that I outlined above?? BTW, anyone who wants a PFO test done with the saline as I described above should NOT ask for a PFO test, but rather a Bubble study, a saline injection study, or a contrast study. Make sure your doctor and technician know someting about what is going on. Steve -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
