ABP 90217A Operations Manual
3-2
General
Measurement Ranges
Heart Rate: 40 to 180 bpm; Pressure: 60 to 260 mmHg for systolic, 30 to 200 mmHg for
diastolic, and 40 to 230 mmHg for mean arterial values.
Pressure Measurement Method
Oscillometric
Automatic Measurement Intervals
Adjustable from 6 minutes (minimum) to 120 minutes (maximum); up to 12 different
periods can be independently programmed, including an interval during which no readings
are taken.
Measurement Time
Typically 35-50 seconds.
Number of Measurements
240 measurements using standard size adult cuff; stores results of 240 readings in memory.
Cuff Pressure
Initial inflation to 165 mmHg; thereafter, the cuff inflates to approximately 30 mmHg above
the previous systolic.
Maximum Cuff Pressure
Up to 270 mmHg; may be set during initialization.
Note: Cuff Pressure may be limited to a pressure lower than the unit’s absolute
maximum.
Auto-zeroing
Pressure automatically zeroed before each reading.
Artifact Rejection
Discriminates between pressure signals, patientmovement, and respiratory artifact.
Cuff Inflation/Deflation
Inflation and deflation rates under microprocessor control.
Data Storage System
Nonvolatile; information retained until reprogrammed; timing of events provided by real-
time clock.
Digital Display
4-digit, 7 segment, liquid crystal display; systolic, diastolic, and heart rate information
alternately displayed; time display and blinking colon provided to indicate when the unit is
ON.
