Ensure that the breath is held
throughout the countdown. The
beep will sound during the last
three seconds of the countdown.
Once the countdown reaches zero, exhale
slowly but gently into the mouthpiece. Aim
to empty the lungs as much as possible.
If the patient cannot hold their breath for
the full 15 seconds, they should commence
exhalation at a comfortable point, but still
exhale completely.
The display will show a rising ppm value
alongside an equivalent %COHb reading.
The coloured LEDs will light up according
to the selected user profile.
The sounder will beeps at an increasing
frequency, according to the concentration
of CO measured. To temporarily mute the
sounder, single click the button.
The peak reading during the breath
exhalation will remain on the
display. The test is complete
when the pointer and ‘return’
symbols appear at the bottom
of the display.
At this point, a single click of the button will
temporarily silence the sounder, if it is on.
To start another breath test, double click the
button to return to the main display. A new
mouthpiece should be used with every test.
Removing the D-piece between tests will
allow fresh air to circulate around the
sensor. It is good practice to wash your
hands after removing the D-piece.
If no further tests are required, the piCO
+
should be turned off by holding the button
down for three seconds. If left on, the piCO
+
will automatically turn off after five minutes
of inactivity.
To re-calibrate the instrument, follow the
instructions on page 11.
To change the user profile from adult to
adolescent (or a custom profile if one has
been set using the COdata
+
user software),
see the instructions on page 13.
To permanently silence the sounder during
the breath test, follow the instructions on
page 14.
