摘要
A noise-immune blood pressure measurement system filters out high frequency noise and blood pulses. The system also recognizes and filters out slow, large noise signals in the range of 0.5 Hz. Such noise signals result when a patient wearing the system makes slow, large finger movements, or is slowly transported by a vehicle over a large bump, for instance. The system accurately derives systolic, mean arterial, and diastolic pressures even when used in a noisy emergency vehicle or battlefield situation.
