Claim 0:
1. A system for determining a likelihood of a condition for inducing pressure ulcers comprising:
a measurement device having one or more sensors configured to measure pressure from the weight of a human patient;
a processor; and
computer memory having computer-usable instructions stored thereon that when executed by the processor perform operations comprising:
acquire a series of pressure measurements from the measurement device, including pressure measurements received during a first time interval,
determine a set of pressure measurement time series including a first time series comprising the pressure measurements received during the first time interval;
determine a multi-taper frequency power spectrum utilizing the first time series,
determine a linear regression for each of two piece-wise linear segments of the power spectrum, each of the regressions having a first-order coefficient,
based on the regressions, determine a frequency cut-point where the two piece-wise linear segments join,
perform a comparison against noise alpha values utilizing the regression coefficients, based on the comparison, determine a likelihood that the first time period has conditions likely to induce pressure injury, and
initiate an action based on the determined likelihood that the first time period has conditions likely to induce pressure injury.
