Vital Sign Monitor Nibp
Philips IntelliVue monitors use the automated oscillometric NIBP technique to measure the systolic, diastolic, and mean arterial pressures. The only direct method for measuring BP is an invasive arterial line. Oscillometric methods estimate blood pressure.
Description
Philips IntelliVue monitors use the automated oscillometric NIBP technique to measure the systolic, diastolic, and mean arterial pressures. The only direct method for measuring BP is an invasive arterial line. Oscillometric methods estimate blood pressure.
All NIBP oscillometric devices use proprietary algorithms known only to the manufacturer. The algorithms can be modified by the device manufacturer and there are no requirements for such changes to be reported. Therefore, different devices, even from the same manufacturer are not interchangeable. Philips IntelliVue monitors can be configured to be interchangeable by selecting the same reference standard algorithm on all devices.
Oscillometry has become the preferred method for automated non-invasive blood pressure (NIBP) monitoring3,4 in most clinical settings. It is increasingly used as an alternative to the invasive blood pressure measurement. Studies show that, especially in critical cases (arrhythmia, vasoconstriction, hypertension, shock), oscillometric devices are in general more accurate and consistent than devices using other non-invasive measuring techniques. However, the oscillometric measurement method does have its limitations.
This Application Note discusses the technical developments in the Philips IntelliVue non-invasive blood pressure measurements (NIBP). This includes the choices of reference standards, and the clinical validation of measurement accuracy for available reference standards.
