Warnings
● When cleaning the monitor, never use
alcohol, cleaning agents containing
alcohol, or other organic solvents, as
these vapours will damage the H
2
sensor
inside.
● Under no circumstances should the
instrument be immersed in or splashed
with liquid.
● The device cannot diagnose a specic
condition; only indicate a possible range
of conditions.
● People with lung disease or chest
ailments may not be able to achieve
the full breath-hold. In such cases, the
user should inhale and hold their breath
for as long as possible when the breath
test is started, and exhale, if necessary,
before the countdown has completed.
Alternatively, the user can use the face
mask sampling mode.
● If the
icon is displayed during
start-up, calibration is due. Please refer
to page 13 for instructions. The unit may
give false readings if not calibrated.
● If the
icon is displayed during
start-up, the D-piece requires changing.
It is recommended that the D-piece
is changed every month, or more
frequently if it is visibly soiled.
● The battery life is indicated by the
icon. When the
icon is displayed, the
batteries should be changed.
● The disposable Flatpak
™
mouthpieces
are for single use only. Reuse can
increase the risk of cross-infection.
● See Bedfont’s Infection Control and
Maintenance Guidelines for further
information on infection control.
● Measurements from the face mask
sampling method may be lower than
when using the mouthpiece. This should
be considered when interpreting the
results.
● Do not cover the exhaust port as this
may affect the accuracy of the test.
● Remove the D-piece between uses to
allow fresh air to circulate around the
sensor.
● The Gastro+ must be switched on in
fresh air to ensure an accurate zero.
Contraindications
● Temperature may affect the accuracy
of the Gastro
+
. The instrument should
be calibrated at 21°C (±4°C). If the
Gastro
+
is used at a lower temperature
than when it was calibrated, readings
may be lower. When used at a higher
temperature than calibrated, readings
may be higher.
