5.2 TAKING SAMPLES
After zeroing the display, the instrument is ready for sampling. The following steps detail
the sample procedure:
1) From ON MODE, press the
ENTER
button. This
will advance the instrument to SAMPLE MODE
starting a series of 3 sample cycles where 3
separate breath samples will be taken. The screen
shown to the right will be displayed which shows a
“HOLD” countdown timer at the bottom of the
display. During this 3-minute time period, the
patient should wait with his/her mouth closed to allow a proper breath sample to
accumulate. The patient should breath through the nose and refrain from talking.
2) When the countdown timer fully elapses, there
will be 3 rapid “beeps” indicating the start of the first
35-second sample period. The timer label will
indicate “SAMPLING” as shown on the right and
the timer will begin it’s 35 second countdown.
There will be a “beep” every 3 seconds during the
SAMPLE cycle. At this point, the patient should put
the sample straw into his/her mouth as detailed previously in section 4.2. As sample is
drawn from the mouth, the displayed value will begin to rise until it hits a peak value after
which it will begin to decline. At this point the patient may remove the straw from his/her
mouth and wait until the next SAMPLE cycle with mouth closed.
4) At the end of the SAMPLE cycle, there will again
be 3 rapid “beeps” indicating the beginning of the
next HOLD cycle. The timer label will indicate
“HOLD” and the 3-minute timer will begin again.
The PEAK value from the SAMPLE cycle just
completed will be displayed above the timer
display. The patient should again wait with mouth
closed as in step 1.
