Description
Hyperbalic Index, HBI
High blood pressure index
Hypobalic Index
Low blood pressure index
Hyperbalic Area
Time integral of the blood pressure values
exceeding the limits.
24-hour blood pressure data is plotted on a
trend bar graph and an integral is
performed on the area exceeding the user-
defined limits.
Expressed as an index per day.
Usually, the risk is managed by comparing
the data with the HBI value of a healthy
person according to age and sex.
Hypobalic Area
Time integral of the blood pressure values
not reaching the limits.
24-hour blood pressure data is plotted on a
trend bar graph and an integral is
performed on the area not reaching the
user-defined limits.
Expressed as an index per day.
Usually, the risk is managed by comparing
the data with the HBI value of a healthy
person according to age and sex.
HBI-sys
The limits of the systolic blood pressure to HBI.
Set the limits of the blood pressures during
sleep (at night) and while awake (by day).
HBI-dia
The limits of the diastolic blood pressure to HBI.
Set the limits of the blood pressures during
sleep (at night) and while awake (by day).
