Go Direct
Respiration Belt

(Order Code GDX-RB)

Go Direct Respiration Belt uses a force
sensor and an adjustable nylon strap to measure respiration effort and rate. An
LED indicator provides feedback so belt tension can be optimized for best
results. Respiration rate is reported within the software, which makes
comparison studies betweens subjects or experiments easy to do. The sensor can
also be used measure steps and step rate. The following are some activities and
experiments that can be performed using the Go Direct Respiration Belt:

l Study how respiration rate changes after exercise or holding of breath.
l Study how respiration effort changes after exercise or holding of breath.
l Compare resting respiration parameters of athletes and non-athletes.
l Use the built-in pedometer to compare step rate while walking and running.

Identifying the Sensor

When two or more sensors are connected, the sensors can be identified by
tapping or clicking Identify in Sensor Information.

Using the Product

Place the Go Direct Respiration Belt around the chest or abdomen of the
subject. The sensor does not need to rest on the skin; it can be worn over
clothing. Secure the sensor to the subject using the strap and clips provided. For
best results, position the sensor box so it is located just below the sternum of
the subject. The tension indicator light is located in the bottom left corner of the
sensor label, just below the checkmark. If the light is not on, tighten the strap
until the light turns green. Loosen the strap if the light turns red. A red light
indicates too much tension.

Connect the sensor following the steps in the Getting Started section of the user
manual.

Channels

Go Direct Respiration Belt has four measurement channels:

l Force
l Respiration Rate
l Steps
l Step Rate

Force

Force is a default channel that is active when the sensor is connected. The force
channel measures respiration effort. This is the force exerted by the chest during
respiration. Inhalation will be observed as an increase in force. Exhalation will
be observed as a decrease in force.

Respiration Rate

Respiration Rate is the other default channel that is active when the sensor is
connected. This channel detects inhalations and calculates the number of breaths
per minute (BPM). The sample window for the calculation is 30 seconds. The
advance interval is 10 seconds. The value will update every 10 seconds.

Steps

The Steps channel reports the number of steps that are detected by the sensor.
You should zero this channel before collecting data.

Step Rate

The Step Rate channel steps per minute (SPM). The sample window for the
calculation is 10 seconds. The advance interval is 10 seconds. The value will
update every 10 seconds.

Calibrating the Sensor

Force

The channel is factory calibrated. You should never have to perform a new
calibration for the Go Direct Respiration Belt. If you would like to calibrate the
sensor, use a one-point calibration. Place the sensor on a flat surface with the
label facing upward. Enter 0 N as the known force.

Respiration Rate

The channel is factory calibrated.

Steps

The channel is factory calibrated.

Step Rate

The channel is factory calibrated.
