1. A system for a user to monitoring a patient, comprising:
a) one or more pressure-sensing devices, wherein each of the pressure-sensing devices comprises a pressure-sensitive region configured to:
be overlaid on one of one or more pressure ulcer-prone body parts of a body of the patient;
and
sense force applied to the body and generates a signal representative of a magnitude of the force,
and wherein each of the pressure-sensing devices is configured to generate data comprising two pressure measurements from different times based on the sensed force;
b) a controller comprising a communication unit;
a computational unit comprising:
a processor; and
a non-transient computer-readable memory comprising instructions that, when executed by the processor, causes the computational unit to:
i) obtain the data transmitted by the one or more pressure-sensing devices;
ii) processing the two pressure measurements from different times of the data to generate a processed pressure datum, wherein the processing comprises calculating a time-differential of the data: dP(t)/dt, where P(t) is a function comprising a temporal sequence of the pressure measurements value, pt; and
iii) determine whether the processed pressure datum meets a threshold value; and
c) a user-interface unit comprising an output unit configured to display an output comprising:
the data, or the processed pressure datum; and/or
an indication of whether the threshold value is met by the data.
