Abstract
Provided herein is a method for automatically controlling inspired oxygen delivery, including: receiving signals representing a plurality of input oxygen saturation (SpO) values for a patient; generating control values based on the input SpOvalues and a target SpOvalue; and generating output inspired oxygen concentration (FiO) values based on the control values and reference inspired oxygen concentration (rFiO) values; wherein the control values include: immediate control values, generated based on the input SpOvalues, the target SpOvalue, and an immediate gain coefficient; accumulation control values, generated based on the input SpOvalues, the target SpOvalue, and an accumulation gain coefficient; and predictive control values, generated based on the input SpOvalues, the target SpOvalue, and a predictive gain coefficient; wherein the immediate gain coefficient is determined based on the rFiOvalue; and wherein a non-linear compensation weighting is applied to the accumulation control value based on a predetermined non-linear relationship between partial pressure of arterial oxygen (PaO) and SpO.
