4.3 Tablet Display and Interaction
If you purchased your VetTab with a tablet, the tablet monitoring application is pre-
installed and ready to connect. If you are using your own tablet you can download the
Vmed VetTab monitoring application at no charge from Google Play or from the Vmed
Technology support website:
https://www.vmedtechnology.com/downloads_support.htm
NOTE
In order to install the Android app from the Vmed website you will need
to follow the instructions provided on our website to enable
“sideloading” of apps onto your Android device, which involves
disabling some security features within Android.
NOTE
VetTab Application is compatible with Android version 8.1 (Oreo) and
above only. For connection procedure see section 4.3.3 below.
4.3.1 VetTab Android App Monitoring Display
The VetTab Android app starts with the monitoring screen, which has parameter and
waveform data as presented below. Additionally, the right side of the screen has several
icons with which the user can interact. These allow the user to make a connection to a
VetTab monitor, initiate a Blood Pressure cycle, toggle the sound or adjust settings in a
separate Settings screen. Refer to Figure 4 below for illustration.
The VetTab Android app is designed for live-monitoring only and does not record
monitoring data. However, it does provide the ability to see both the waveform and
numerical data in a larger context, depending upon the size of the Android device on
which it is used. Through this app you can set up and activate a periodic blood pressure
measurement cycle and be notified when any of the shown parameters exceed their
individual alarm limits. You may also edit these alarm parameters using the Settings
screen (described in section 4.3.2).

In addition to the icons on the right of the screen and the waveform and parameter data
the app’s monitoring screen gives additional information at the top. There you can find
the currently connected VetTab device (including its ID number in case you have more
than one VetTab device). You can also see the elapsed Bluetooth connection time, which
will reset the next time you establish a Bluetooth connection with your VetTab monitor.
4.3.2 VetTab App Settings
The Settings screen allows the user to modify default high and low alarm limits for the
Heart Rate, SpO2, Systolic, Diastolic, MAP, Temperature and Respiration parameters.
Figure 5 - Settings Screen
Each category has a blue heading such as “Heart Rate”, “Respiration”, etc. Each
category has its own toggle switch that allows the user to enable or disable the alarms
for that category (when the switch is blue then it is on and when it is gray then it is off,
disabling alarms for that category). Each parameter type also has both a high alarm limit
and a low alarm limit. You may change what is shown by default by tapping its text box
and then typing a new number in its place.

16
Additionally, you may set the temperature unit and the interval that the blood pressure
measurement will use between measurements. Demo Mode may also be selected
through the toggle switch under “General.” Enabling this and then returning to the
Monitoring screen will allow you to show pre-recorded vitals data on the screen once
the “connect” button is pressed.
If any change is made to a value or switch within the Settings screen you will need to
press the “Save Settings” button at the lower left corner of the screen in order to keep
these changes and return to the Monitoring screen.
Figure 6 - Save Settings Button
Instead, you may return to the Monitoring screen without saving any modified settings
by tapping the Android Back button at the bottom center of the screen.
Figure 7 - Android Back Button
4.3.3 Bluetooth Connection to Android Device
The internal Bluetooth on your Android device allows it to link wirelessly to the VetTab
communicating its monitoring data for display in the Android app.
Once the Vmed VetTab app has been installed on your Android device and you have
verified that Bluetooth is enabled on it, you can make use of the app by following these
instructions.
1. In your list of apps, select the Vmed VetTab app.
Figure 8 - Vmed VetTab App Icon

17
2. When it first opens it will show the main monitoring screen (see Figure 9).
Figure 9 - VetTab App Monitoring Screen
3. Press the Select button on the front of the VetTab to turn it on and make sure that
the Bluetooth icon ( ) is blinking at the top of the LCD indicating that Bluetooth is
enabled. If it is not blinking, follow the instructions in section 4.2 to enable it.
4. Touch the Connect button (see section 4.3.1) to initiate the Bluetooth connection.
Once your VetTab is discovered it will appear in the following list. If other nearby
VetTab monitors are also on, they will also be visible. Select your VetTab from the
list to initiate pairing.
Figure 10 - Bluetooth Discovery of VetTab
IMPORTANT
The VetTab will appear in this list during Bluetooth discovery with a
unique digital ID number corresponding to the VetTab ID number
printed on the back label (in Figure 10 it is “937A18”). Pay attention to
this ID number if more than one nearby VetTab is turned on to ensure
you connect to the right one.

18
5. If your VetTab has not already been paired with this Android device, you will see
the following dialog. Select “Pair” to initiate the pairing. However, if your VetTab
has already been paired with this Android device then proceed to step 6.
Figure 11 - Bluetooth Pairing Dialog
6. The screen will now show that you are connected and waveform data will begin
traversing each waveform box.
4.3.4 SpO2 Sensor Status Display
Whenever the VetTab is not measuring a certain vital sign parameter from the patient
then that vital sign’s parameter box will display three hyphens (“---”) to indicate that there
is no value available. For the SpO2parameter there is an additional message at the
bottom left corner (see Figure 12) which gives further information about why there is no
available SpO2parameter value.
Figure 12 - SpO2Status Description
The descriptions indicate such reasons as:
•Sensor is unplugged –the SpO2sensor cable is not plugged into the VetTab
•No connection to patient –the SpO2sensor cable is plugged into the VetTab,
but the sensor itself is not connected to the patient
•Searching for pulse signal –the SpO2sensor may be attached to the patient but
is unable to detect a pulse to measure (this usually only takes a few moments)
•Pulse search timed out –Too much time passed while the SpO2sensor was
unable to detect a pulse to measure

19
4.3.5 NIBP Error Message Display
Occasionally when performing a blood pressure measurement, the VetTab may not be
able to return a numerical result. In such an instance it should produce an error message
in the bottom left corner of the NIBP parameter box describing why this is.
Figure 13 - NIBP Error Message Display
Some of the more common errors are listed below with descriptions of what may have
caused them or what you may do to correct them.
•BP error 3: cuff pressure leak:
oCause: no cuff is attached to the hose
oCause: leak in the cuff so that it cannot inflate completely
oFix: attach a cuff without any leaks
•BP error 5: check cuff position:
oCause: the cuff is not connected to or improperly positioned on the patient
oCause: the wrong cuff size is used on the patient
oFix: follow instructions in section 6.3 for proper cuff placement and
position
•BP error 7: invalid result:
oCause: hose is kinked or blocked
oCause: cuff not properly connected to patient
oCause: cuff is too large (or loosely wrapped around patient)
oFix: make sure hose is not kinked or obstructed
oFix: follow instructions in section 6.3 for proper cuff placement and
position
•BP error 8: measurement cancelled:
oCause: the measurement was cancelled either by the user tapping the BP
button on the app or by selecting and activating BP on the VetTab screen.
This error would only appear in the middle of a measurement and not during
the interval between them.

20
4.3.6 NIBP Measurement Cycles
When monitoring a patient during a longer procedure you may wish to measure the blood
pressure multiple times at regular intervals. The automatic NIBP cycle feature allows you
to do so without having to remember to initiate a measurement each time. By selecting
one of several choices for “Automatic Interval” under the NIBP section of the App Settings
screen (see Figure 5 of section 4.3.2), you may designate the NIBP to automatically
initiate a new measurement 1, 3, 5, 10 or 15 minutes after the previous measurement
concludes. Or, you may turn off automatic measurement by selecting “Off”. When it is off
each tap of the BP button will initiate a single measurement.
In the top right of the NIBP parameter box are 3 separate kinds of indicators which show
what state you are in for NIBP measurement cycles (see table below).
BP cycle is off. This ‘X’ symbol indicates that the
BP is neither measuring nor waiting to start a new
automatic measurement. To initiate a new cycle,
either tap the BP button on the app or select and
activate the BP icon on the VetTab remote device.
BP is measuring. This circular animation where
the center periodically grows larger and smaller
indicates that a blood pressure measurement is
currently active with the cuff at least partially
inflated. To cancel a measurement before it is
complete simply tap the BP button on the app or
select and activate the BP icon on the VetTab
remote device.
BP is in the automatic waiting interval: This text
shows a countdown in minutes and seconds from
the time interval selected in the App Settings. It
appears at the end of each measurement unless
“Off” is selected. Once it reaches “00:00” it will
automatically initiate a new BP measurement.
During this interval if you tap the BP button of the
app then it will cancel the BP cycle and return to
the Off state. Tapping the BP button again will start
a new measurement. However, if in the waiting
interval and you activate the BP icon on the VetTab
remote device then it will begin a new BP
measurement directly.
