1 INTRODUCTION

This manual applies to the model numbers BT1512 and BT1528.

The BodiTrak LT is an easy to use, stretchable, pressure and shear monitoring system
that is applied on top of a seating surface. It assists in identifying and managing areas
on a patient’s skin where they may be experiencing high pressures and shear forces. It
is a powerful tool to help prevent tissue trauma, increase patient comfort, monitor
support surface performance and educate both clients and caregivers.

Using an attached Tablet, a person can easily access Risk and Gradient information.
The software also includes a timer option with selectable time periods. The LT provides
the patient or caregiver with essential information for improving patient care and
reducing the expense of healing wounds.

3 WARNINGS

3.1 This equipment complies with IEC 60601-1, 3rd edition, which states the requirements for

basic safety and essential performance. Using this equipment with accessories or cables
other than those provided by Vista Medical may result in non-compliance with those
requirements. No modification of this equipment is allowed.

3.2 This equipment may cause radio interference or may disrupt the operation of nearby
equipment. It may be necessary to take mitigation measures such as:

• Reorienting or relocating the affected receiving antenna

• Increasing the separation between the equipment and the receiver

• Connecting the equipment into an outlet on a circuit different from that to which

the receiver is connected

• Consulting the dealer or a qualified radio/TV technician for help

3.3 When external equipment such as a computer is connected to this equipment it should
comply with EN 60950 for IT equipment, or the EN 60601-1-1 series for medical electrical
equipment. Equipment not complying with EN 60601-1-1 shall be kept outside the patient
environment, as defined in the standard, at least 1.5 m from the patient or the patient
support.

3.4 Electrical interference, such as electrical transients or bursts, may cause the sensing mat
to malfunction. Avoid using in close proximity to other equipment such as motors that have
a high amount of electrical switching. If unavoidable, verify normal operation prior to use.

3.5 The USB connector with this warning symbol for electrostatic discharge (ESD)
should not be touched directly, and connections should not be made, unless precautionary
procedures are used. Users should be trained to recognize the symbol and to discharge
themselves by touching grounded metal prior to handling the USB connector or plugging it
in. If function stops due to ESD, unplug the mat, reboot the computer, and plug the mat
back in.

5 USING THE BODITRAK LT SYSTEM

5.1 From the tablet Home screen tap the BodiTrak LT shortcut, or go to Apps Drawer and select
the icon for BodiTrak LT.

5.2 Select “Start Mapping”.

5.3 If the blue mats appear on the User Interface the connection was successful.

5.4 Key Item: The system has 2 modes: On-the-Go scanning and Multiple Comparison. You

can switch back and forth by tapping the “square in a square” icon.

5.5.1 On-the-Go Scanning Mode

This mode is intended to provide a quick and easy way to assess a person’s situation
on a surface over time. The scanning starts as soon as you plug in the sensing mat
and select ‘start mapping’.

The display is divided to show two seat images as shown here in Figure 1. The image
on the left displays normal force pressures. The image on the right is for gradient and
risk considerations.

On the left hand side of the display you will observe:

• a color bar indicating the level of pressure from 5-200 mmHg, or a chosen
pressure range

• the center of pressure on the mat, represented by a white dot

• the Dispersion Index box: a rectangle defined as 8 sensors across and 6 sensors

down which you can drag to a desired location (for example the ischial-sacrum
area) to calculate the Dispersion Index

• statistics which are useful for considering solutions and are explained as follows:

Dispersion Index (%) –The sum of pressure distributed over a region (for example
the ischial tuberosity (IT) and the sacral-coccygeal region) divided by the sum of
pressure readings over the entire sensor mat, expressed as a percentage. A value
of 50% or more is indicative of a potential risk of skin trauma.

Peak Pressure Index – The average of the highest recorded pressure values
within a 9 to10cm2 area (the contact area of an IT). PPI is a better comparative
bench mark than average seat pressures.

Sensing Area (in2) – The area of the mat the client is resting on which is displaying
above the minimum setting, e.g. 5 mmHg. Generally you want a larger sensing or
contact area as this means the area of support has increased.

C of V (%) – The coefficient of variation shows how evenly the pressure is
distributed across a support surface. It is expressed as a percentage, and is
normally the inverse of the sensing area. It is better to have a lower CoV value, but
be careful to compare to the pressure map; you may have a low CoV but still have a
high localized force somewhere in the seat surface.

On the right side of the display you will observe:

• Gradient and Risk display choices, as shown here in Figure 2

GRADIENT (spatial pressure)

RISK (pressure vs. time)

Figure 2 – Risk and Gradient

RISK TAB – The Risk tab will be highlighted when chosen. The pressure

map indicates tissue loading over time and is expressed in mmHg/hour. It
helps the client or caregiver to understand where the skin may be most at
risk of tissue trauma and repositioning may be required. (The software is
based on Reswick-Rogers pressure/time curve.)

GRADIENT TAB – The Gradient tab will be highlighted when chosen. The
pressure map identifies areas of the skin that may be affected by shear
forces and is expressed as mmHg/cm. Areas of fastest change in pressure
over the surface of the seat are displayed as hotter colors. It is believed
that where pressures change quickly from one location to another there is
a risk of shear occurring to tissue.

• a start timer and time indicator that can sound an alarm at a chosen time to remind
a client to shift their weight

• a Reset Risk button used to reset the risk display

On the top of the display you will observe:

• A three dots icon which gives you a drop-down showing two options, Data Port
Connection and Settings. If you tap on Settings you will see the following options:

USER SETTINGS

• A circular arrow icon which will rotate the view of the mat 180 degrees.

5.5.2 Multiple Comparison Mode

The Multiple Comparison is a comparison tool for considering solutions to seating
issues. A series of up to four images are taken in sequence to allow for side by side
comparison.

To begin the comparison wizard click the “square in a square” icon as shown in
Figure 5.

6 CARE OF THE BODITRAK MAT

• Do not pull on or carry the mat by the USB cable.

• Place the mat gently on surfaces by using the corners.

• Do not pivot on the mat.

• Do not pull on the edges of the mat while it is under a client.

• The covering on the pressure sensing mat should not be in direct contact with broken

skin.

• Do not pinch the mat between moving components of a support surface.

• Do not fold the mat

• Store the mat flat or in the original packaging by rolling the mat around the foam tube

and storing in the shipping cylinder.

• If your mat has a ferrite installed on the USB cable do not remove it.

• It is the operator's responsibility to ensure all cables are in good condition; inspect all

cables for nicks or abrasions prior to each use.

7 CLEANING THE BODITRAK MAT

BodiTrak pressure sensing mats are typically covered in polyurethane coated nylon/Lycra
stretch fabric.

• Unplug the mat before cleaning.

• For daily cleaning, we recommend wiping down with a damp, not wet cloth using a mild

soap and water solution.

• Mild alcohol based cleaners and cleaners containing no more than 10% bleach in non­wetting amounts may also be used.

• Other cleaners / disinfectants sold under the following names may also be used:
Viraguard, Cavicide, Vitre Tb, and SeptFx.

• Undiluted bleach and Hydrogen Peroxide are not recommended.

• Cleaning products or disinfectants must be thoroughly wiped off after using them.

• Allow the mat to dry thoroughly before use or storage.
