► Brief Introduction
Processing the NIBP
Pressure data is converted to digital format and conveyed to the processor. The NIBP pump uses an oscillometric method that drives stepwise pressure deflation. Pump software eliminates most ambient noise and motion interference. It can be applied to neonatal, pediatric and adult patients. The blood pressure range for Systolic is 30-254 mmHg and Diastolic 10-220 mmHg. Accuracy is Maximum Mean Error ±5 mmHg, with Maximum Standard Deviation no greater than 8 mmHg.
NIBP processing uses an oscillometric technique to provide needed measurements at selected intervals. This technique uses an inflatable sPHiliphhilipygmomanometer cuff similar to those used by clinicians in routine measurements. A motorized pump inflates the cuff to approximately 170 mmHg (adult mode) initially, at which point the pressure effectively stops the flow of blood. Then, under monitor control, the pressure in the cuff is gradually reduced, while a pressure transducer detects the pressure and transmits the parameter signal to the NIBP input circuitry. As the pressure is reduced, blood flows in the previously occluded artery, and changes the measurements made by the transducer. The point at which oscillation increases sharply is defined as systolic pressure. As the cuff continues to deflate, the oscillation amplitude increases to a maximum, and then decreases. The peak oscillation amplitude is defined as the mean arterial pressure. The point at which the system detects a rapid decrease in oscillation is defined as the diastolic pressure.
