Principles of noninvasive blood pressure determination (NIBP): DINAMAP SuperSTAT algorithm
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.
