US Patent No: 5348004

Electronic processor for pulse oximeter

---

Abstract

---

An electronic processor for calculating in vivo blood oxygenation concentration levels using pulsed light that eliminates both requirements for comparing photosensor signal amplitudes with analog/digital circuit dynamic ranges and also adjusting electronic processor parameters. The invention uses monolithic a/d converters with expanded capacity and a microcontroller/processor with a pulse control module to synchronize switching in an oversampling demodulator with pulsing of light sources to overcome prior circuitry limitations that consumed substantial central processor capacity.
