BREATH TECH QUESTIONS AND VERIFIED SOLUTIONS
A QT has the most direct effect of the breath test? T or F - ✔✔True The intoxilyzer 8000C
can measure up to _______ BAC - ✔✔600mg/100mL blood What is the proper terminology
for the result when the breath test is complete? (saying the accused blew 120) - ✔✔120mg
of alcohol in 100 mL of blood How long does the power on process for the intoxilyzer
8000C take? - ✔✔30 minutes After how many days will the alcohol standard solution
expire? - ✔✔15 days What must be performed when the configure standard is changed? -
✔✔configure standard What is the temperature of the simulator and it's acceptable range?
- ✔✔34 degrees celsius (can be within 0.2) so 33.8 and 34.2 is acceptable What is the
target value for the system calibration check and what is it's acceptable range? - ✔✔- 100 -
must be within 10 % either way so 90 or 110 is okay as well Will the intoxilyzer 8000C
produce an exception message during an Esc, Esc "C"? - ✔✔No What makes the most
accurate results for a breath test? - ✔✔deep lung air (alveolar) If someone is
hyperventilating (breathing very quickly) what happens to their breath? - ✔✔cools it If
someone is hypoventilating (holding breath) what happens to their breath? - ✔✔warms it
What are the 4 criteria evaluated and must be met before a BAC will be produced? - ✔✔-
flow rate (0.15 L/S) - time (1 second) - volume (1.1 litre) - level slope Approximately what
percentage of available breath must be discarded before "deep lung air" is reached? -
✔✔70% Will a poor quality sample underestimate the BAC? - ✔✔Yes How many "suitable"
samples must be obtained - ✔✔2 Is there a limit on how many samples you can take? -
✔✔no limit How is the second breath test for the subject conducted? - ✔✔Esc, Esc "R" If
you have two tests that are not within 20mg of one another, the third can can be conducted
after ________ minutes - ✔✔17 minutes What are the 3 audible tones? - ✔✔- single tone
(pass) - continuous tone (flow rate met, breath analysis) - high low tone - fail Explain how
the intoxilyzer works in general terms - ✔✔- Breath is blown through an approved
instrument - Breath goes through an infared sensor - Infared detector conducts light energy
to voltage - Result is a mg of alcohol in ml of blood What is the message when the results
are 20mg apart from one another? - ✔✔no 020 agreement (re test subject) What is the
certificate of analyst? - ✔✔- legal document for alcohol standard solution - proves solution
is suitable for accuracy of intoxilyzer 8000C Who is the QT designated by? - ✔✔soliciter
general What does good agreement mean? - ✔✔2 suitable samples that do not differ from
20mg of alcohol in 100 mL of blood What does the certificate of analyst help form? -
✔✔conclusive proof What are 5 times the alcohol standard solution needs to be changed?
- ✔✔- 50 calibration checks conducted - past 15 days (expired) - no certificate of analyst -
, solution expired - system calibration check outside range for unknown reason Can you
purchase an intoxilyzer 8000C from any hardware store? - ✔✔no Is it possible to
incorrectly hook up a simulator to the intoxilyzer 8000C? - ✔✔yes When all 4 criteria are
met what will appear in front of the breath test result? - ✔✔a zero What is the breath test
sequence? - ✔✔- 5 system blank checks - 2 diagnostic checks - 1 system calibration check
- 1 subject test A system blank test cannot be more than _____ mg / 100mL - ✔✔10mg If the
measurement exceeds 10mg/100mL the exception message will be? - ✔✔ambient fail If
the sample chamber could not be decreased to an acceptable alcohol level, what will the
exception message be? - ✔✔purge fail Ambient conditions may lower the system
calibration check and the subject test results. T or F? - ✔✔True What is the purpose of a
diagnostic check? - ✔✔verify the instrument is in proper working order How many
components are there in a diagnostic check? - ✔✔9 Does the QT calibrate the intoxilyzer
8000C? - ✔✔No - all the QT does is CHECK the calibration What are the 3 quality
assurance checks prior to testing and why are they performed? - ✔✔- self test - system
calibration check - diagnostic check These are performed to ensure the intoxilyzer 8000C
is in working order How would you qualify yourself as a qualified technician in court? - ✔✔-
date received training - date of last in service training - published in gazette - approx
number of tests performed to date - designated by soliciter general How would you identify
the approved instrument in court? - ✔✔Intoxilyzer 8000C and serial number How would
you identify the alcohol standard in court? - ✔✔manufacturer and LOT number The
qualified technician is the only person authorized by law to perform breath tests - T or F -
✔✔True How should you coach the subject to provide a breath sample? - ✔✔- take
moderate inhalation - continuous breath at moderate force - continue to provide the
sample until i say stop or the tone stops - demonstrate self breath test Under what 4
circumstances are a diagnostic check conducted? - ✔✔- breath test being conducted -
Esc, Esc "D" - Intoxilyzer starting up - Intoxilyzer coming out of stand by What does ITP
stand for? - ✔✔Internal Test Procedure What is the purpose of ITP? - ✔✔- Occurs when the
amount of IR light that reaches the detectors is decreased to simulate a BAC of mg of
alcohol in 100 mL of blood - makes sure detectors work and checks calibration internally
Why is the simulator heated to 34 degrees celsius? - ✔✔because it is the temperature of
the human breath What are the criteria for the breath alcohol results to be conclusive
proof of BAC at the time of analysis? - ✔✔- approved instrument - operated by QT - system
black test not more than 10mg - system calibration check within 10% of target value -
interval between two tests at least 15 minutes - results rounded down and do not differ by
more than 20mg - use of certified alcohol standard Why would you deem a breath sample
