  2. Spirometry & Related Testing Equipment • Learning Objectives • Describe at least one volume displacement spirometer • List at least two principles used by flow-sensing spirometers to measure volume

  3. Spirometry & Related Testing Equipment • Spirometer • Definition • Any Device used to measure lung volumes and flows

  4. Volume Displacement Spriometers • Water-Seal Spirometers (Collins, Stead-Wells)

  5. Volume Displacement Spriometers • Water-Seal Spirometers • Bell factor • Kymograph • 32,160,1920 mm/min • ATPS to BTPS • Potentiometer • Flow/Volume • FV Loop

  6. Spirometers • ATPS to BTPS Coversion • Actual values must be corrected to body temperature pressure saturated (BTPS)

  7. Volume Displacement Spriometers • Water-Seal Spirometers • Problems • Cracks → Leaks • Positioning • Too high • Too low • Infection Control • Hoses • Mouth Pieces • Filters

  8. Volume Displacement Spriometers • Dry Rolling-Seal Spirometers

  9. Volume Displacement Spriometers • Bellows – Type Spirometer

  10. Flow-Sensing Devices • Flow-Sensing Spirometers (pneumotachometers) • Devices that measure gas flow

  11. Flow-Sensing Devices • Turbine (impeller)

  12. Flow-Sensing Devices • Turbine (impeller) • Wright Spirometer • VC, VT, VE • Flows 3-300L/min • Not used for FVC • Compact • Gas sterilized

  13. Flow-Sensing Devices • Pressure Differential Flow Sensors

  14. Flow-Sensing Devices • Pressure Differential Flow Sensors • Fleich (capillary tubes) • Silverman (screens) • Heating element to reduce condensation • Recalibrate after cleaning

  15. Flow-Sensing Devices • Heated-Wire Flow Sensors

  16. Spirometry & Related Testing Equipment • Portable Spirometers • Flow-sensing spirometer interface with a laptop computer

  17. Spirometry & Related Testing Equipment • Portable Spirometers • Portable spirometer using plug in cards

  18. Spirometry & Related Testing Equipment • Portable Spirometers • Handheld “office” spirometers

  19. Spirometer Calibration • 3 – Liter Syringe • Used for volume calibration of volume-based and flow-based spirometers • ATS Standards • +/- 3% • Or +/- 0.05 L Whichever is greater
