1. 1 out of every 14 admissions
results in a hospital acquired ulcer
SoreSight
They cost hospitals
$12B a year that
is not reimbursed
They extend hospital
stays an average
of 11 days
Give foresight to your sore sites!
Electrodes
are placed
in the area
of interest
Readings are
taken of the
impedance
in that area
and the
surrounding
tissue
at 50 kHz
A
signifigant
change in
readings
indicates a
problem
Determining severity of
early ulcers is often hard
due to subjectivity
Pressure ulcers are more likely to form
on bony prominences such as these
Our device serves as a warning that an
area may be injured and should be
treated more carefully
What is bioimpedance?
Measurement of passive electrical
properties of biological materials
Non-invasive, low cost, low power
High sensitivity, low specificity
Can detect macroscopic changes in
tissue shape and composition
High pressure causes blood flow to be
occluded, resulting in hypoxia and
eventually areas of necrosis

An increased reading is indicative of
cell swelling, which can mean they are
in danger of breakdown
An decreased reading is indicative of
cell death, as signals can pass freely
through the tissue
They are more likely to
form in bedbound
and elderly patients
Ulcers increase
mortality
risk 2-6x

A novel solution is needed
to help prevent this painful,
expensive problem
The farther an ulcer progresses, the
more difficult and expensive it is to
treat
