1Gas Chromatography (Absorption Type) NEED TO ADD THIS [blank_start]QUESTION BACK[blank_end]
- AQUESTION BACK
2Advantages: Analyzes [blank_start]many gases[blank_end] at once. Very accurate
Disadvantages: Requires more [blank_start]time[blank_end] than other analyzers.
Affected by: [blank_start]H2O[blank_end] and [blank_start]CO2[blank_end]
Measures: [blank_start]Ne[blank_end], [blank_start]O2[blank_end], [blank_start]N2[blank_end], [blank_start]CO[blank_end]- ACO

- CO2
- DNe

- Hmany gases
3CO2/CO/CH4
AKA: [blank_start]Infrared[blank_end] Absorption Analyzer
Quick response time is suitable for [blank_start]DLCO[blank_end]
Calibrate: to room air ([blank_start]0[blank_end]%) and known concentration (.[blank_start]3[blank_end]%) CO then re-zero and use [blank_start]gain[blank_end] to match read out to [blank_start]known[blank_end] concentration.
Changes in altitude do [blank_start]NOT[blank_end] affect readings.- AInfrared
- BDLCO
- C0
- D3
- Egain
- Fknown
- GNOT
4Helium analyzer
Also Known as: [blank_start]Thermal[blank_end] Conductivity or [blank_start]Wheatstone[blank_end] Bridge
Measures: Gas [blank_start]percentage[blank_end]
Calibration: To room air ([blank_start]0[blank_end]%) and known ([blank_start]10[blank_end]%) then use gain to adjust to [blank_start]known[blank_end] amount.
Do not use with [blank_start]flammable[blank_end] gases.
Used with Helium dilution tests.- AThermal

- Gflammable
5Mass Spectometry
Function: Sample is drawn in by vacuum to the [blank_start]ionization[blank_end] chamber. Individual gases are [blank_start]separated[blank_end] and analyzed.
Measures: Gas percentages
Advantages: [blank_start]Rapid[blank_end] Response time, breath by breath analysis, multiple gas analysis
Can analyze: [blank_start]He[blank_end], [blank_start]N2[blank_end], [blank_start]O2[blank_end], [blank_start]CO2[blank_end]
Disadvantages: Expensive, large, high maintenance
Most Suitable for: analysis of [blank_start]several[blank_end] patient at once rather than individual testing.- Aionization
- Bseparated
- CRapid
- DHe
- EN2
- FO2
- GCO2
- Hseveral
6Nitrogen analyzer
Also known as: [blank_start]Geissler[blank_end] Tube Ionizer
Sample is pumped into [blank_start]ionization[blank_end] chamber where light is emitted and monitored by a phototube. Intensity of light is directly [blank_start]proportional[blank_end] to N2%
Measures gas percentage
Capable of breath by breath analysis
Calibration: To zero with [blank_start]100[blank_end]% O2 and a [blank_start]known[blank_end] concentration.- AGeissler
- Bionization
- Cproportional
- D100
- Eknown
7O2 Analyzers
Galvanic [blank_start]Fuel[blank_end] Cell Analyzer: Measures partial [blank_start]pressure[blank_end] and displays [blank_start]FiO2[blank_end] as %.
If unable to calibrate you should replace the [blank_start]fuel[blank_end] cell.
Calibration during exercise testing: Low [blank_start]12[blank_end]-[blank_start]14[blank_end]% and high [blank_start]21[blank_end]%
Poloragraphic Analyzer
Similar to galvanic but uses a [blank_start]battery[blank_end]
Analogous to the [blank_start]Clark[blank_end] electrode
Calibration is to [blank_start]21[blank_end]% and [blank_start]100[blank_end]%- AFuel
