Equipment overview: Overall principles of operation
Full NIBP determination sequence for adult
(specific pressure values are examples only)
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 8 mmHg. The parameter then deflates the cuff (to zero
detected pressure), analyzes the stored data, and updates the screen.
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 for an NIBP determination.
SuperSTAT NIBP - auto mode
Systolic search
If systolic pressure is not found, the SuperSTAT algorithm can search at cuff
pressures higher than the initial target pressure. The algorithm will inflate above
the initial target pressure to obtain more data in the systolic region. The pressure
is limited to the maximum allowed for the selected patient type.
