    NIBP Module, M-NIBP INTRODUCTION This section provides information for the maintenance and service of the Non-Invasive Blood Pressure parameter module, M-NIBP. The Non-Invasive Blood Pressure Module, M-NIBP, is a double width plug-in module designed for use with the S/5 monitors. Figure 1 Non-invasive blood pressure Module, M-NIBP NOTE: Do not use identical modules in the same monitor simultaneously.

  • Page 8: Functional Description

    Datex-Ohmeda S/5 monitors FUNCTIONAL DESCRIPTION 2.1 Measurement principle NIBP (Non-Invasive Blood Pressure) is an indirect method for measuring blood pressure. The NIBP measurement is performed according to the oscillometric measuring principle. The cuff is inflated with a pressure slightly higher than the presumed systolic pressure, and deflated at a speed based on the patient’s pulse, collecting data from the oscillations caused by the pulsating...
