Can we please take this off [EE]. I really think the PICLIST is not a good place to be practicing medicine. - - Bob Ammerman RAm Systems -----Original Message----- From: piclist-bounces@mit.edu On Behalf Of Art Sent: Thursday, April 5, 2018 3:54 PM To: piclist@mit.edu Subject: Re: [EE] sleep apnea home test? Hi Denny, The fitbit and Apple monitoring you mention is an accelerometer, attached t= o body limbs. They detect how much the patient moves in the night in order to evaluate whether the patients paralysis is normal during sleep AND whether the patients eyes open when they are in normal sleep paralysis. These functions are controlled in a part of the brain just above the brain stem, and an abnormal correlation often indicates the patients need for B6. Note that serum B6 in the blood is useless-the cells have to be examined directl= y because it's what's on the inside of the cell that counts! Video and sound perform a similar function and additionally the sound can monitor breathing to see if breathing actually stops during sleep! I ordered a 32 GB SD card for my cell phone and plan to take some overnight video (with sound) soon. Regards and ty for the info!
