AB  - OBJECTIVE: To evaluate three methods aimed at the reconstruction of brachial 
      pressure from non-invasive finger arterial pressure measurements as implemented 
      in the Finometer trade mark, (FMS, Finapres Measurement Systems, Arnhem, 
      Netherlands), the successor to the Finapres trade mark (TNO Biomedical 
      Instrumentation, Amsterdam, Netherlands). METHODS: Finger arterial pressure 
      (FinAP) may differ from intra-brachial pressure (BAP). Pulse shape differences 
      are removed by applying a generalized waveform filter. Pressure level differences 
      are corrected by a generalized level correction equation using filtered systolic 
      and diastolic levels and by level calibration, which uses an additional 
      return-to-flow (RTF) systolic pressure measurement on the ipsilateral upper arm 
      for an individual calibration of the reconstructed brachial pressure. VALIDATION: 
      These methods were validated in 37 subjects, aged 41 to 83 years after a cardiac 
      catheterization procedure. Intra-brachial and Finometer pressures were recorded 
      simultaneously. Finometer pressures were compared after application of waveform 
      filtering and level correction (flcAP), and after an additional RTF calibration 
      (reBAP). RESULTS: Finger arterial systolic, diastolic and mean pressures for the 
      group differed from BAP by -9.7 +/- 13.0, -11.6 +/- 8.0 and -16.3 +/- 7.9 mmHg 
      (mean +/- SD) respectively. Similarly flcAP differed by -1.1 +/- 10.7, -0.2 +/- 
      6.8 and -1.5 +/- 6.6 mmHg and reBAP differed by 3.1 +/- 7.6, 4.0 +/- 5.6 and 2.7 
      +/- 4.7 mmHg. CONCLUSION: Reconstruction of BAP from FinAP as implemented in the 
      Finometer reduces the pressure differences, with an individual RTF calibration to 
      well within AAMI requirements.
