AB  - It has been discussed by other authors that clinically relevant mistakes can 
      occur in the measurement of invasive blood pressure. For this reason, we 
      investigated all pressure lines used in our hospital. Our studies showed that 
      exact measurement of invasive blood pressure using fluid-filled pressure 
      measuring systems is not possible in the arterial, venous or pulmonal-arterial 
      areas. Iatrogen mistakes should be excluded by working carefully. Exact knowledge 
      of the physical qualities and the dynamic response of the fluid-filled pressure 
      line used is required for judging the measuring accuracy. In clinical practice, 
      measurement errors can amount to 40%. An acknowledged method to verifying errors 
      is the Gabarith system developed by Billiet and Colardyn, which can determine the 
      extent of the biggest-possible error after investigating the pressure line. A 
      reduction of measurement error to below 2% can be achieved by carefully combining 
      the individual components of the measuring system and, if necessary, by using an 
      industrially-produced damping device (resonance overshoot eliminator [R.O.S.E.]). 
      In this way, standardized measuring systems can be made available for clinical 
      practice.
