I work in a sleep research lab. We have a couple of Masimo pulse oximeters that report pulse oximetry values in terms of integers (e.g. 90, 91, 92, etc.).

Now our principle investigators used to use an Ohmeda Biox 3700 that reported data via analog output in a nice (noisy) curve (e.g. after filtering, 90, 90.1, 90.3, 90.4, etc.).

There's some discussion that because of the lack of decimal, the Masimo is useless for data reporting. The Ohmeda though is from the 90s and I can't find any documentation that indicates if taking the decimal is even acceptable for the device's resolution. Any thoughts?

  • $\begingroup$ Welcome to Biology.SE! This may be a good question, but it's unclear exactly what you're asking for. Are you asking about the details of a particular model of pulse oximeter (probably best to ask the manufacturer), or are you asking about the utility and accuracy of pulse oximetry in general? The more specific your question, the better, provided it is on topic. I would also invite you take the tour and visit the help center. $\endgroup$ – De Novo Mar 27 '19 at 19:47
