Finometer® Model-2 User’s Guide 17
1 Introduction
This introduction represents a general description of Finometer®
Model-2 in terms of methods used, with literature references, features,
available derived parameters from the blood pressure waveform and
bias and precision of the principal blood pressure parameters.

What is Finometer® Model-2?
Finometer® Model-2 is an instrument to monitor finger arterial
pressure continuously. Finometer® Model-2 is the successor of the
well-known Finapres (TNO and Ohmeda models) and provides the
measurement of blood pressure in a finger based on the arterial
volume-clamp method of the Czech physiologist Peñáz, and the
Physiocal - physiological calibration - criteria for the proper unloading
of the finger arteries of Wesseling. Hydrostatic pressure changes due
to relatively slow movement of the hand are compensated by a so-
called Height Correction Unit.
Finometer® Model-2 is a novel stationary device for measuring
continuous non-invasive blood pressure and fits in between Portapres
(ambulatory Finapres) and Finometer® Model-1 (refined version of
Finapres with AAMI SP10 accuracy and precision.)
Finometer® Model-2 provides the analog blood pressure waveform in
the same way as Finapres and can be connected to a remote PC to
store the full finger pressure waveform and beat-to-beat derived
parameters on the PC by using the BeatScope® Easy software.
