Patent ID: 8789530

Claim:
An automatic system for controlling SpO 2 in the blood of a patient, the system comprising: a. an adaptive microcontroller; b. a device that controls the variable adjustment of FiO 2 delivered to the patient through a blend valve; and c. a monitoring device, wherein the adaptive microcontroller receives signals from the monitoring device pertaining to clinical measurements of the patient, processes the signals with dynamic adaptability through an algorithm and sends corresponding signals to the device that controls the variable adjustment of FiO 2 delivered to the patient depending on the signals received by the microcontroller from the monitoring device, wherein the microcontroller is in direct communication with the monitoring device through an inbound/outbound electronic communication means selected from the group consisting of a serial port adapter, USB adapter, firewire, Ethernet cable, wireless communication, and combinations thereof, and wherein the algorithm comprises an estimation system consisting of a discrete parameter-estimating extended Kalman filter and extended state observer.
