Key result
A novel particle filtering algorithm accurately extracted respiratory rates from 6 to 90 breaths/min from pulse oximeters, remaining robust even with sudden rate changes of 24 breaths/min.
Why the study?
Does a particle filtering algorithm combining TIV and TVAR models accurately extract respiratory rates from pulse oximeters in healthy subjects?
Does a particle filtering algorithm combining TIV and TVAR models accurately extract respiratory rates from pulse oximeters in healthy subjects?
A novel particle filtering algorithm can accurately extract a wide range of respiratory rates directly from pulse oximeter signals, even during sudden changes or high noise.
