Nutritional support feeding efficiency

A system for automated enteral feeding of a subject, comprising:

• at least one hardware processor executing a code for:
• measuring, over a portion of a time interval, a resting energy expenditure (REE) of the subject based on CO2 production rate and/or O2 consumption rate estimates of the subject made by measurements of at least one sensor;
• computing a target nutritional goal to reach at an end of the time interval, wherein the target nutritional goal comprises a volume to be delivered (VTBD) by the end of the time interval that matches to a target amount of energy expenditure of the subject over the time interval computed by extrapolating the REE from the portion to the time interval;
• computing a target feeding profile defining a target feeding delivery rate that is up to a defined maximal feeding delivery rate for enteral feeding of the subject by an automated enteral feeding device for reaching the VTBD by the end of the time interval;
• continuously monitoring the real time energy expenditure of the subject over the time interval based on continuous measurements of the REE measurements computed from CO2 production rate and/or O2 consumption rate estimates of the subject made by measurements of the at least one sensor;
• dynamically adapting the target nutritional goal and corresponding VTBD to compute a maximum VTBD (max VTBD) to reach at the end of the time interval according to dynamic adaptations of the monitored real time energy expenditure of the subject;
• dynamically sending a control signal to the automated enteral feeding device that automatically delivers feedings to the subject for adapting the target feeding delivery rate and the corresponding target feeding profile for a remaining portion of the time interval for reaching the max VTBD by the end of the time interval,
• wherein the target feeding profile matches to changes of the REE and does not exceed the defined maximal feeding delivery rate.
