What does gas Allows for measurement of several different gases
chromatography do? And with one detector. Absorption type. Remember it's not
what type is it? Key thing fast, can't measure breath by breath.
to remember about this 1?
What type of gas does Helium. But neon is substituted for helium in the
Gas Chromatrography measurement of lung volumes and diffusing capacity
require?
ADV: Can analyze many gases at one time. Very
What are 2 ADV and
Accurate.
DisADV of Gas
Dis: Requires more time than others. Affected by
Chromatography
water and CO2
What gases dows Gas Neon, 02, N2, CO.
Chromatography
measure?
What are 2 features of Drawn by a vacuum into an ionization chamber. And
mass spectrometry. can measure more than one gas at a time.
ADV: Rapid response time. Capable of breath by
breath analysis. Allows for multiple gas analysis of
Advantages and DisADV He,n2,o2, C02.
of Mass Spectrometry:
DisAdv: Very expensive. Large in size. Requires high
maintenance.
, When is Mass Spec most Most suitable for analysis of several patients at once
suitable? rather than for individual testing.
When troubleshooting Increase gain until 100% is reached. If too high then
Mass Spec, what should decrease the gain.
you do if sum of all gases
is less than 100%?
How does Carbon Has chopper motor, which breaks up infrared light by
Dioxide/Carbon pulses.
Monoxide/Methane (CH4)
work?
Where is the CH4 Infrared Connected to C/motor and Chopper blade
source connected?
What does the Infrared Measures C02 or CO
absorption analyzer
measure in the Ch4?
How do you calibrate Calibrate to RA (0%) and a known concentration (.3%
CH4? What do you have CO), then rezero. Adjust gain up or down to make it
to remember about the match
gain?
Is CH4 affected by any No
changes in partial
pressure?
What can affect Long sample lines and moisture. Can affect and delay
calibration in CH4? response time.
What is another name for Thermal conductivity or Wheatstone Bridge
Helium analyzer? Name 2
How do you calibrate for Calibrate to RA (0%) and a known amount (10%), then
Helium? rezero. Allow He to clear to rezero
What is important safety Do not use w/ flammable gases. Could lead to
rule to remember when explosion.
using He?
