Abstract

A computational method for generating a feeding score for an individual infant based upon a comparison of feeding factor measurements obtained from the individual infant, values associated with the feeding factor measurements, and feeding parameter metrics from a population of infants having a similar gestational age as the individual infant.

Claims

1. A computational method for generating a feeding score for an individual infant indicative of feeding performance comprising the following steps:

a) receiving digitized data corresponding to two or more feeding factor measurements obtained from the individual infant, wherein said feeding factor measurements are indicative of physical, physiological, or behavioral responses produced during at least one feeding session for the individual infant;

b) providing at least one feeding parameter relating said two or more feeding factor measurements, and calculating, for said at least one feeding parameter, a value based on said two or more feeding factor measurements;

c) providing a set of feeding parameter metrics comprising at least one distribution of values derived from feeding sessions of a population of infants having a similar gestational age as the individual infant;

d) comparing the value for said at least one feeding parameter with the set of feeding parameter metrics and deriving a referenced feeding score for the individual infant relative to the set of feeding parameter metrics;

e) outputting the referenced feeding score to a user as a percentile or a percentile range within the at least one distribution of values comprising the feeding parameter metrics, wherein said referenced feeding score represents the feeding performance of the individual infant, and wherein steps a) through e) are performed on a suitably programmed computer.

2. The method of claim 1, wherein said feeding parameter is derived by performing at least one statistical operation on an aggregation of a feeding factor event and at least one additional feature related to the feeding factor event.

3. The method of claim 2, wherein said feeding parameter is selected from the group consisting of a time of a number of sucks, average pressure peaks for all suck events, an average number of sucks per sucking burst, a total burst time as a percentage of an observation interval, a mean variance and a coefficient of variation of time intervals between sucking pressure peak and peak inspiration, and a breathing rate during sucking bursts.
