A2.2 Finger cuffs
A2.2.1 Protective measures for finger cuff
Cuff pressures on the finger up to 350 mmHg are practically painless and do no
harm unless applied for long periods. Electrical circuits of the Finapres Nova do
not touch the skin, and are not in contact with body fluids. The following
measures are taken for the safety and comfort of the patient monitored and the
convenience of the operator.
A2.2.2 Electrical
 Low cuff LED current (<30 mA), voltage (<1.8 V) and power dissipation
(<50mW) prevent undue heating or skin irritation, or electrical hazard.
 An electrical short circuit in the cuff or the instrument depressurizes the cuff
within 1 second.
 An interrupted Frontend cable or cuff cable depressurizes the cuff within 1
second.
 All analog signal outputs are fully short circuit proof.
