Introduction

The PS-2133 Respiration Rate Sensor consists of an inflat­able Respiration Belt and a Relative Pressure Sensor. The
sensor includes a hose and coupler kit (not shown).

The sensor is designed to work with a PASPORT -compatible
interface (such as the UI-5100 850 Universal Interface) and
PASCO data acquisition software (such as PASCO Cap­stone). With the data acquisition software, the sensor can be
used to measure change in pressure over a period of time.
The pressure changes correspond to the respiration (breath­ing) rate.

The Respiration Belt has the following features:

• Quick Connector that can be attached to the pressure

• Squeeze bulb with release valve for inflating and deflat-

To interface

• Start the PASCO data acquisition software. Set up a data
display in the software.

Using the PASCO Capstone Software

• Click the “Hardware Setup” icon in the Tools palette to
open the “Hardware Setup” panel. Confirm that the Rel­ative Pressure Sensor icon appears with the interface’s
icon.

• Click one of the display templates in the workbook
page, or double-click an icon in the “Displays” palette to
open a data display.

Using the SPARKvue Software

• Start the interface and connect the sensor to an input
port on a SPARK Science device.

• In the sensor parameter screen, touch ‘Relative Pres­sure’ to highlight it, and then touch ‘Show’ to open a
graph display.

Using the Xplorer GLX Datalogger

• Start the GLX datalogger and connect the sensor to one
of the input ports on the top of the GLX.

• The screen will show a graph of Relative Pressure ver­sus Time.

Using the Respiration Belt

• First, deflate the belt. Open the release valve on the
squeeze bulb (turn the knob counter-clockwise) and
press on the belt to push any air out.

• Place the part of the belt that has the tubes against your
chest first. When this part is against your chest, the layer
of ‘pile’ will face away from your chest. Then place the
left side of the belt over the first part so the
hook-and-pile layers match each other. The belt should
be snug around the chest, but not so tight that breathing
is restricted.

• Connect the Quick Connector tube from the Respiration
Belt to the Quick Connector pressure port on the sensor.

• Arrange the belt around the upper part of your chest so
that the part that has the tubes on it is on the right side of
the body with the tubes hanging down from the bottom
edge of the belt (see the diagram).

Inflating the Respiration Belt

Close the release valve on the squeeze bulb (turn the knob
clockwise). Make sure that the sensor is connected to the
other tube. Squeeze the bulb several times to inflate the rub­ber air bladder inside the belt. It may take as many as twenty
squeezes to inflate the bladder . When the bladder is inflated,
the belt will be more snug around your chest.

Warning: Do not over inflate. Over inflation can damage the
air bladder and possibly cause bodily injury.

Deflating the Respiration Belt

Open the release valve on the squeeze bulb (turn the knob
counter-clockwise). Use your hands to push the air out of the
bladder. You can also deflate the belt by disconnecting the
tube from the pressure port on the sensor. Twist the quick
connector counter-clockwise to disconnect it.

Data

• Click “Record” ( ), touch the ‘Start’ button ( ),
or press the “Record” button ( ) to begin recording
data.

• Click “Stop” ( ), touch the ‘Stop’ button ( ) or
press the “Record” button ( ) again to end recording
data.

Calculate Respiration Rate

The ‘peaks’ on a plot of relative pressure versus time can be
counted to determine the respiration rate (breaths per unit of
time). However, you can also create a calculation to automat­ically measure the respiration rate. The respiration rate or
frequency of breaths is the reciprocal of the period between
breaths.

Using PASCO Capstone to Create a Calculation

• Click ‘Calculator’ in the Tools palette to open the Cal­culator window.

• Click ‘New’ and select ‘Add New Equation’ from the
list.

The calculation changes to
“Respiration Rate=60/period(10,10,1,|)”
where the vertical line before the last parentheses repre­sents a blinking cursor.

• The period function determines the period of the data
source by detecting peaks and measuring the time
between them. The first term represents the peak%, the
second term is the valley%, the third term is the time
over which the measurement is made, and the fourth
term – to be inserted – will be the source of the data. In
this case, the data source is the Relative Pressure.

• Click the ‘Insert Data’ icon ( ) and select ‘Relative
Pressure (kPa)’ from the list.

• In the calculation, change “10,10,1,” to “30,30,5,” and
then click ‘Accept’. The calculation appears as shown:

• Highlight ‘units’ and delete it.

Using SPARKvue to Create a Calculation

• Touch the Experiment Tools icon ( ) and select ‘Cal­culated Data’ from the list. The ‘Enter calculations’
screen opens.

“Calc1=” appears in the text area. Rename this to
Respirator Rate=.

• On the right side of the equal sign, enter “60/” (without
the quotation marks).

• In the lower part of the Calculator window, click ‘Spe­cial’ and then click ‘period’.

• Touch the ‘abc’ icon to switch to the keyboard layout.
Enter “respirationrate=60/” (without quotation marks).

• Touch the ‘123’ icon to switch to the calcu lator layout.

Respiration Rate Sensor Introduction

• Touch the icon under “Functions:” until it shows “Spe­cial 1”.

• Touch the ‘period’ icon. The calculation changes to
show the following:
respirationrate=60/period(90,10,5,|)
where the vertical line before the last parentheses repre­sents the blinking cursor. The period function has four
items: peak%, valley%, time interval, and data source.
The cursor is in the space where the data source is
placed.

• Touch the ‘Measurements’ icon. Touch ‘Relative Pres­sure’ in the list. The calculation changes to show the fol­lowing:
respirationrate=60/period(90,10,5,[Relative Pres­sure(kPa)])

• T ouch “Done”.

Note: When the belt is connected to the Relative Pressure
Sensor, the sensor measures the change in pressure in the air
bladder in the belt as the lungs expand and contract.
Although the pressure of the chest cavity causes pressure
against the belt, the pressure measured in the belt is not the
actual pressure in the lungs.
