Hi Sven, Thanks a lot for the info on the OEM modules for pulse oximetry. Being an electronics engineer it's not easy to spend a lot of money,especially in the RSA, because of the unfavorable exchange rate. My Mother(76y) suffers from COPD and requires SPo2 readings to be taken at regular intervals. She is on supplementary oxygen for 24 hours a day. If I could monitor some vital functions over a period of time, it could mean a lot to her regarding her quality of live. I planned to design the oximeter myself but with your info and the manual from Kathy I could finish my project much sooner. Thanks again. Kind regards, Rob. -----Original Message----- From: pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU]On Behalf Of Milton Medicinteknik KB, Vikingstad, Sweden Sent: Sunday, September 30, 2001 4:11 PM To: PICLIST@MITVMA.MIT.EDU Subject: [pic]: can you make an oxygen saturation monitor with a pic?? Hi ! I have not followed this trace, but if you are designing a pulse oximeter I wish you the best of luck ! Very much effort has been put into noice supression and especially motion artefact supression. Currently avaliable commercial systems are very good at this ! If you are a hobbyist and want to do some experimnets, sure ! BUT if you really need oxymetric data, there are 2 (3??) vendors that supply OEM Modules. Very very much time us saved by purchasing one of these from http://www.nonin.com Look under http://www.nonin.com/OEM.html That module gives data output as RS232 including heart rate. Stable and reliable. 200 some dollars is nothing, if you are payed by the hour.
