Use of Drager Pump & Tubes
Preparation
Pump Leak Test Insert unopened tube into the socketSqueeze pump completely and releasePump is adequately leak-proof if the
end-of-stroke volume indicator has not appeared after 15 minutes
Remove tube from socketPress button to reset counter to zero
Preparing the TubeSelect 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.
Preparing the TubePull 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.
Making a MeasurementCheck 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.
Carbon Dioxide TubesDetermination of CO2 in airMeasuring range – 100 to 3000ppmNumber of strokes – 10Time of measurement – approx. 4 minsColour change – white to violet
Carbon Dioxide
(Simple Asphyxiants)
Acute EffectsRapid loss of consciousnessComaAnoxic brain injury
Chronic EffectsResidual anoxic injury
Exposure LimitsAtmospheric oxygen should > 18% at
normal barometric pressure
General ConsiderationsAsphyxiants gases are those inhalants
that act predominantly by oxygen deprivation.
This may occur by simply displacing oxygen from inspired air.
Occupational & Environmental ExposureOne of confined space exposure
(storage tanks or mines)Product of combustion and fermentation
processes.Natural volcanic lake release
