NBP
The patient's tolerance for the cuff pressure (i.e. stress) when an NBP
measurement is made is an important factor to consider when choosing
patient category. The amount of stress is determined by:
Since a neonate can usually tolerate less stress than a pediatric patient,
and a pediatric patient can tolerate less than an adult, the System
algorithm has category-dependent safety values. If the cuff pressure
exceeds these values for more than a given time period, the cuff
immediately deflates and a severe INOP Alarm is given. These values are
adapted to normal physiological values.

Examples
Overpressure
Overpressure occurs if the cuff maintains a pressure above the safety
value for more than two seconds. The safety values are:
Adult:
Pediatric:
Neonate:
Continuous
Continuous Pressure occurs if, for any reason, a safety pressure value is
Pressure
maintained in the cuff for more than a safety period, dependent on the
patient category.
