The TNO Finapres and the commercial OhmedaFinapres are no longer available.1.4 PortapresThe Portapres blood pressure device is similar to Finapres and manufactured byTNO TPD Biomedical Instrumentation. Portapres has a number of features thatmake the device suitable for ambulatory use.• The device is light weight and battery powered• Portapres measures blood pressure in two (adjacent) fingers. By pressurizingthe finger cuffs alternately the slight discomfort when a cuff is wrapped arounda finger longer than about an hour, can be prevented.• Portapres uses a hydrostatic height correction system to compensate forvertical movement of the hand with respect to heart level and the concomitantpressure changes in the finger blood pressure.• Portapres stores the data of 24 hr finger arterial blood pressure waveform,hydrostatic height, event marker, and status messages on its built-in FlashMemory Card.• A Control unit is used to enter data, to set-up the device and to start ameasurement. During a measurement this unit may be disconnected. Thisreduces the overall weight of the device.1.5 FinometerFinometer is a blood pressure device similar to Finapres, but with a number ofsignificant extensions.
