NEULOG BLOOD PRESSURE SENSOR GUIDE

NeuLog blood pressure sensor
NUL-222 Carolina # 39651

The NeuLog blood pressure sensor can be used for any science experiment or activity
which involves blood pressure measurements such as in the fields of Exercise
Science, Biology, Physiology, Human Health, etc.

The sensor comes pre-calibrated so you can start experimentation right out of the box
using any of the following guides.

Just a few of the thousands of possible experimental subjects that can be done with
the NUL-222 sensors are: exercise studies, human health studies, athlete
comparisons, blood pressure abnormalities, and many more.

The blood pressure sensor uses the following units of measure:

 Millimeters of mercury (mm Hg): A standard non-SI pressure measurement.
 Analog arbitrary units (Arb): An arbitrary value used to demonstrate

waveforms without a unit.

 Millimeters of mercury and analog arbitrary units (mm Hg + Arb): A

combination of both units.

Using the blood pressure cuff:

To accurately record blood pressure rates you must first properly attach the blood
pressure cuff to the user. Note: The cuff works through clothing though try to
minimize layers for the best readings possible.

1. Unwrap the blood pressure cuff and locate the Velcro connection pads.

2. Situate the blood pressure cuff so the Velcro pads are facing outwards.

3. Wrap the blood pressure cuff tightly, without causing discomfort, around the
user’s upper arm.

4. Ensure that the rubber tubing (connected directly to the blood pressure cuff)
is situated only a couple of centimeters above the inner elbow.

5. Close the air pressure release valve by twisting the metallic knob until it
tightens.

6. Using the hand-pump fill the blood pressure cuff’s bladder until it forms a
snug but not uncomfortable fit (around 170 mm Hg should suffice).

7. Run an experiment following one of the following guides.

8. Loosen the pressure valve to allow a pressure decrease of about 3 to 4 mm
Hg per second.

Calculating heart rate, systolic, diastolic, and mean arterial pressure (MAP):

Using the NeuLog software the systolic, diastolic, and MAP blood pressure values can
easily be calculated:

1. Conduct an experiment following the “Using the blood pressure cuff” guide
and one of the following guides for setup.

2. After your data has been collected, click the “Select Zone” button
underneath the graph.

3. Highlight the region of the data that has a steady decline with visible heart
beats by clicking and dragging on the graph.

4. Click on the “Show Functions” button.

5. Select the sensor you wish to calculate for.

6. Select the “Functions” button.

7. Click on “Blood Pressure” and an information box will appear on the right
hand side of the graph.

Systolic:
Systolic pressure is the pressure which blood exerts on the arterial walls while the

heart is beating (the maximum pressure achieved). This value ideally is in the 90 to
120 mmHg range for adults and roughly 100 mmHg for children aged 6 to 9.

Diastolic:
The pressure which blood exerts on the arterial walls while the heart is relaxed in

between beats (the minimum pressure achieved). This value ideally is in the 60 to 80
mmHg range for adults and around 65 mmHg for children aged 6 to 9

Quick start procedure:

PC or Mac Computer

Materials needed:

 NUL-222 Blood pressure Sensor
 USB-200 USB Module
 A USB to mini USB cable (which comes with the USB-200)

Your blood pressure sensor needs to be connected to a USB-200 module. The USB­200 module then connects to a computer via a USB to mini-USB cable. Please note
that you cannot plug the blood pressure sensor directly into the computer.

NEULOG BLOOD PRESSURE SENSOR GUIDE

Resident PC software and browser based software can be downloaded for free at
www.NeuLog.com/dowload as well as a full software user guide. Note: Make sure not
to download and install both types of software, they will conflict on the computer.

Procedure:

1. Install the NeuLog software

2. Connect the USB-200 module to the PC or Mac

3. Connect the blood pressure sensor to the USB-200 module (they directly
plug together). Please note there is no calibration required for this sensor.

4. Open the NeuLog software.

5. Once a blood pressure sensor logo appears on the left side of the screen
the probe has been automatically identified and you can begin
experimentation.

6. If the blood pressure sensor is not automatically identified then click the
“Search for sensors” icon to find the sensor.

7. Select the “On-line experiment” button; this will open a graph below.

8. Click on the “Module setup” button located on the blood pressure sensor
icon in the module window to change the sensor settings if need be.

9. Click on the experiment set up button to change the experiment settings if
need be (experiment duration for example).

10. The blood pressure sensor will give a live reading in the box to the left of the
screen while plugged in.

11. To run an experiment and collect data click “Run experiment”.

12. To end data collection early, click “Stop experiment”.

Tablet, smart phone device

Materials needed:

 NUL-222 Blood pressure Sensor
 WIFI-201 WIFI module
 BAT-200 Battery

Your blood pressure sensor needs to be connected to a WIFI-201 module. The WIFI­201 module will create a closed NeuLog wifi network which will stream the NeuLog
data to a device of your choosing. Once your device is wirelessly connected to the
NeuLog network you can run experiments and collect data through a browser of your
choosing.

Procedure:

1. Connect the blood pressure sensor directly to the left side of a WIFI-201
module (no wires required).

2. Connect a BAT-200 module to the right side of the WIFI-201 module.

3. Although not required, we recommend plugging the BAT-200 to an outlet
using a USB to micro USB charger (such as a typical cell phone charger).
The WIFI-201 module will run for 15-75 minutes (depending on the sensor)
without being plugged in.

4. For further WIFI-201 instructions or the WIFI-201 quick start guide please
visit www.NeuLog.com/download.

5. The WIFI-201 indicator lights will flash; take no action until the LED to the
far left turns blue.

6. Take your tablet or smart phone and go to the Wi-Fi settings and select the
NeuLog network which matches the WIFI module ID found on the back of
the WIFI-201 device. (NeuLogXXXX for example)

7. Give your device 1-2 minutes to connect to the WIFI-201 network.

8. Once the device is connected go to your browser and type in the website
wifi201.com into the URL bar, then wait for 30-60 seconds.

9. You will see a “Control mode” icon in the browser, click on this icon.

10. The browser will then load a new screen and begin to auto detect the
sensors, this can take a few minutes.

11. If the browser does not auto detect, select “Search for sensors”

12. Once the sensor is found you will see an icon on the left side of the screen
for the blood pressure sensor. The icon will display data in real time.

13. To set the blood pressure sensor’s settings click on “Module setup” button
located on the blood pressure sensor icon on the left side of your screen.

14. To change the experimental settings click the “Experiment setup” button
(experiment duration for example).

15. To run an experiment and collect data click “Run experiment”.
