  1. Use of Drager Pump & Tubes

  2. Preparation

  3. Pump Leak Test • Insert unopened tube into the socket • Squeeze pump completely and release • Pump is adequately leak-proof if the end-of-stroke volume indicator has not appeared after 15 minutes • Remove tube from socket • Press button to reset counter to zero

  4. Preparing the Tube • Select tube for the measurement required. • Follow instructions for use (tube). • Insert tip in opening on the lower pump plate; keep it pressed against the ceramic edge while turning it, so that the glass is scored.

  5. Pull tube over at an angle until the tip breaks off. • Discard broken tip. • Open other end of tube in the same way. • Insert tube into pump, the arrow must point towards the pump.

  6. Making a Measurement • Check number of strokes required for the tube. • Put forefinger and ringfinger in the middle of the lower pump plate and squeeze completely. • Release pump. • Evaluate the result. • Remove used tube from socket. • Flush pump.

  7. Carbon Dioxide Tubes • Determination of CO2 in air • Measuring range – 100 to 3000ppm • Number of strokes – 10 • Time of measurement – approx. 4 mins • Colour change – white to violet

  8. Carbon Dioxide (Simple Asphyxiants)

  9. Acute Effects • Rapid loss of consciousness • Coma • Anoxic brain injury

  10. Chronic Effects • Residual anoxic injury

  11. Exposure Limits • Atmospheric oxygen should > 18% at normal barometric pressure

  12. General Considerations • Asphyxiants gases are those inhalants that act predominantly by oxygen deprivation. • This may occur by simply displacing oxygen from inspired air.

  13. Occupational & Environmental Exposure • One of confined space exposure (storage tanks or mines) • Product of combustion and fermentation processes. • Natural volcanic lake release

  14. Thank You!
