A2.2.3 Cuff pressure
 A cuff pressure greater than 250 mmHg sustained for 2.5 s depressurizes the
cuff within 1 second.
 During the start procedure cuff pressure is limited to a maximum of
295 mmHg lasting less than 2 s.
A2.2.4 General
 If cuff pressure oscillates when measuring finger pressure, although this
presents no hazard or discomfort to the patient, software takes action to
remove the oscillation.
 Fully contracted finger arteries do not allow pressure monitoring. A warning is
send to the Finapres Nova and the finger cuff is depressurized when this is
detected. The Finapres Nova waits maximally 100 s and starts up again.
