PASCO PS-3234 User manual

Wireless Spirometer (PS-3234)
Introduction
The Wireless Spirometer is designed for use with PASCO
Capstone or SPARKvue data collection software. The sensor
allows you to perform respiratory measurements, such as flow
rate, lung volume, and pressure.
NOTE:
•This is NOT a medical device. It is
designed for educational use only and
should not be used in life support, patient
diagnosis, or any other medical process. It
is also not intended for use in graduate
research or industry, including industrial
control or any type of industrial testing.
•Read all instructions before using the
product. Students should be supervised by
their instructors. When using the product,
follow the instructions in this manual and all
applicable local safety guidelines.
•Do not share mouthpieces or filters. The
mouthpieces and filters are intended for a
single occasion, which may include several
tests with the same individual.
CAUTION: In medical settings, pulmonary
function tests are performed under the
supervision of a medical professional. When
using a spirometer without medical supervision,
use extra caution. A person with a medical
condition that may be affected by a pulmonary
function test should NOT use the Wireless
Spirometer. Immediately end use if the subject
experiences breathing difficulty or discomfort.

Getting started
Initial step: Charge the battery
Charge the battery by connecting the micro USB port to any
standard USB charger. The Battery Status LED is solid yellow
while charging. When fully charged, the LED changes to solid
green.

Data collection
Using the sensor requires two people: one to serve as the test
subject, and one to perform data collection.
1. Connect the mouthpiece to the handle as shown below.
Make sure to align the pin on the mouthpiece with the notch
on the handle.
2. Connect the filter to the mouthpiece so that it creates a
snug fit.
3. Tell the subject to hold their breath, place their teeth and
lips on the filter, pinch their nose closed, stand still, and
relax. (See below.)
4. Begin data collection. The sensor will perform a calibration
procedure, as indicated by the Bluetooth Status LED
flashing red. Wait until the light flashes green, then move to
the next step.
5. Guide the test subject through each of the following data
collection steps. Do not show the data to the test subject as
it is collected.
a. Take four normal breaths.
b. Inhale as deeply as possible, then exhale deeply with
maximum effort.
c. Take two normal breaths.
6. Stop data collection.
NOTE: You may need to perform the test a few
times to ensure data is satisfactory. If the data
drifts or the calibration light does not turn green,
refer to Troubleshooting.
Interpreting the data
When performed correctly, a plot of lung volume versus time for
the experiment described in Data collection will yield data like
what is shown above. The following quantities can be obtained
from this plot:
•Tidal Volume (TV)
The volume of one breath, or the amount of air moved into
and out of the lungs during normal breathing.
•Functional Residual Capacity (FRC)
The amount of air left in the lungs after a normal expiration
(FRC = RV + ERV). The typical FRC value is about 2.5 L.
•Inspiratory Capacity (IC)
The maximum amount of air that can be inspired after a
normal expiration (IC = TV + IRV).
•Expiratory Reserve Volume (ERV)
The amount of air moved out of the lungs during a forced
expiration, beyond the level of tidal expiration.
•Inspiratory Reserve Volume (IRV)
The amount of air moved into the lungs during a forced
inspiration, beyond the level of tidal inspiration.
•Forced Expiratory Volume in One Second (FEV1.0)
The volume of air moved out of the lungs in the first second
of a forceful expiration after a maximal inspiration.
•Residual Volume (RV)
The amount of air remaining in the lungs at the end of a
forced expiration. The typical RV value is about 1.2 L.
•Vital Capacity (VC)
The maximum movable amount of air contained by the
lungs (VC = TV + IRV + ERV).
•Total Lung Capacity (TLC)
Maximum volume of air the lungs hold at peak inspiration.

Troubleshooting
You may notice a slow drift or slight fluctuation in the baseline in
your graphs of Total Flow and Lung Volume. In most cases these
can be eliminated with the steps below. Note that slow baseline
changes usually do not significantly affect the measurements of
volumes and capacities that can be found from the graphs.
•Air pressure changes in the environment during the
measurement period can influence the sensor readings.
These pressure changes can be caused by doors opening
or closing, ventilation systems starting or stopping, and air
movement within the testing room, among other potential
sources. Try to reduce the presence of such changes while
collecting data. In most cases, natural environmental
pressure variation is tolerably low over the typical 30
second test period.
•If you observe significant drift across multiple runs, try
switching Steps 3 and 4 in the Data collection procedure,
allowing the sensor to calibrate while resting motionless on
a flat surface before being held to the subject’s mouth.
