At each step the microprocessor stores cuff pressure, the
matched pulse amplitude, and the time between successive
pulses. The stepped deflation and matched pulse detection
continues until diastolic pressure is determined or total cuff
pressure falls below 7 mmHg. The Monitor then deflates the
cuff (to zero detected pressure), analyzes the stored data,
and updates the front panel displays.
The operating cycle is composed of four parts: inflation
time, deflation time, evaluation time, and wait time. Wait
time, which varies from mode to mode, is affected by the
cycle time (Auto mode) or operator intervention (Manual
mode). The figure shows the Basic Operating Cycle.

Systolic Search
If systolic pressure is not found, the Monitor can search at
higher cuff pressures than the initial target pressure. If the
determination is in a late stage, the Monitor will inflate the
cuff to 70 mmHg above the initial target to get better data
in the systolic region. If the determination is in an early
stage, the Monitor will inflate the cuff to 50 mmHg above
the initial target pressure. The maximum pressure allowed in
systolic search is limited by the normal range for cuff
pressures. In any operating mode, if a patient’s systolic
pressure exceeds the inflation pressure of the Monitor, the
Monitor will begin normal deflation sequence, detect the
