Introduction

With the PASPORT Blood Pressure Sensor, students can easily measure heart rate
(beats per minute) and systolic and diastolic arterial blood pressure (millimeters of
mercury). Students gain a greater understanding of the physiology of the circulatory
system when they also learn about the physiology of blood pressure. The systolic and
diastolic pressure provided in the digit display can be used by the student to verify
their own determination of blood pressure from a graph of pressure versus time.

Blood pressure is the force that blood exerts on the walls of blood vessels. This pres­sure is caused by the contraction of the heart and by muscles that surround blood ves­sels. Blood pressure is always highest in the two main arteries that leave the heart.
Because the pressure is usually a little higher in the left artery, blood pressure is usu­ally measured in the brachial artery supplying the left arm.

Blood pressure consists of two measurements: systolic and diastolic pressure. It is
represented as a ratio of systolic pressure to diastolic pressure, for example 130/80
(“one-thirty over eighty”).

In most parts of the world, blood pressure is reported in millimeters of mercury
(mmHg).

Systolic pressure is the pressure of the blood on the artery walls when it leaves the
ventricles at peak ventricular contraction, when the heart is emptying its chambers of
blood. It is the "top number" of the blood pressure ratio. Normal systolic pressure for
a male is approximately 120 mmHg and for females is approximately 110 mmHg.

Diastolic pressure is the pressure of the blood on the artery walls when the ventricles
relax and the heart's chambers fill with blood. It is the "bottom number" of the blood
pressure ratio. Normal diastolic pressure for a male is approximately 80 mmHg and
for females is approximately 70 mmHg.

Systolic and diastolic pressures are affected by various biological and environmental
factors. For example, the salt in a person's diet can cause the kidneys to change the
amount of fluid in our blood, resulting in changes in blood pressure. Diet, stress, exer­cise, body position, drugs, hormonal changes and genetic factors can affect a person's
blood pressure.

About the Sensor

The PASPORT Blood Pressure Sensor consists of a pressure sensor box and a blood
pressure cuff with bulb and valve. The sensor is a digital sphygmomanometer that
measures mean arterial pressure and then calculates systolic and diastolic blood pres­sure and heart rate (in beats per minute).

The blood pressure cuff consists of an inflatable bladder connected by one hose to a
hand pump bulb with a push-button release valve, and by a second hose to the pres­sure sensor box.

The Blood Pressure Sensor can be connected to any
PASPORT interface (such as the SPARK Science
Learning System (SLS) or SPARKlink). The sensor
can be used with the P ASPOR T Extension Cable. This
cable is 2 meters in length, extending the distance a
sensor can reach from a computer or portable
datalogger.

Indicator Light Emitting Diodes

The sensor has two light emitting diodes (LEDs) mounted inside the pressure sensor
case. When they are active, the LEDs can be seen through the case. One is orange and
the other is green.

The orange LED begins to flash as the cuff is being inflated (starting when the pres­sure reaches 50 mmHg). Once the cuff is inflated, the orange LED shines continu­ously while the sensor is making pressure readings. The orange LED goes out when
the air in the cuff is released and the pressure drops to about 35 mmHg. The green
LED flashes to indicate a heart beat.

Usage

Experiment ideas:

• Determine the effects of exercise on blood pressure and heart rate.

• Explore the effects of body position on blood pressure and heart rate.

• Compare the blood pressure and heart rate of students in the class.

Procedure

Sensor Setup

1. First, find a partner. A student cannot measure his or her own blood pressure.

Partner 1 should be the patient and partner 2 should conduct the measurement.

2. Connect the blood pressure cuff to the Blood Pressure Sensor. Align the quick

connector at the end of the tube from the cuff with the quick connector port on
the sensor. Push the quick connector onto the port and turn the connector clock­wise until the connector clicks into place on the port.

3. Connect the Blood Pressure Sensor to a PASPORT interface.

4. If you will be using a computer, connect the PASPORT interface to the com-

puter’s USB port.

5. Create Digits displays of pressure, diastolic pressure, and systolic pressure. Your

may also want to view pressure versus time data in a Graph display.

Cuff and Arm Placement

1. The patient should remove any constrictive clothing or jewelry that may interfere

with the cuff placement.

2. Locate the approximate position of the main artery (brachial artery) on the inside

3. Partner 2 should help the patient wrap the cuff snugly around the upper left arm

4. Use the hook-and-pile material to hold the cuff in place. Position the cuff's bot-

of your upper left arm by pressing with your fingers near the inside edge of your
biceps muscle about five or ten centimeters (cm) above the elbow pit.

above the elbow with the two tubes hanging down (one on each side of the arm).

tom edge at about 2.5 cm (one inch) above the elbow pit.
