1. 2 General Information 2 1 Overview Unlike auscultatory NIBP measurement which uses a stethoscope or microphone the oscillometric method uses the pulses or oscillations in the cuff pressure to determine the patient s blood pressure The cuff is inflated above the systolic pressure then deflated lineatly or step wise When the cuff pressure is high the pulse amplitude is small but as the cuff pressure decreases the pulse amplitude increases and then begins to decrease During deflation the amplitude of each cuff oscillation is measured by the monitor and stored along with the cuff pressure at which the oscillation occurred The oscillation amplitude is then plotted against the cuff pressure to produce the oscillation envelope curve The oscillation envelope is then used to determine the patient s blood pressure It is widely accepted that the mean arterial pressure MAP occurs at the peak of the envelope where the cuff oscillation amplitudes are maximum There are no universally accepted formulas for determining the systolic and diastolic pressures NIBP monitor manufacturers have developed unique proprietary algorithms for estimating the systolic and diastolic pressures from the oscillation envelope AccuSim BP is a compact simulation platform designed to expedite and simplify the testing of non invasive blood pressure NIBP monitoring devices which are based on the oscillometric method General Information Overview Chapter 2

Shift This allows the user to slide the factory preset envelope up or down by X mmHg For example With Shift flashing start with the 120 80 93 preset apply a shift of 5 mmHg using the Down arrow key lt F4 gt The preset will now run as 115 75 88 The display will show the new shifted value that is actually being used Shift is limited to an absolute maximum of 100 mmHg but has additional limits imposed by the range of AccuSim BP itself It is strongly recommended to start with the nearest preset to what you want and shift that by some reasonable amount rather than try to shift a preset by some large amount The shift value will be retained and used for all presets used in this testing session This means the user can easily run a range of tests with the factory presets offset to the users preference or need while working in the same patient mode Adult or Neo This is true for both manual selections and Auto Sequences The Shift setting change will not be retained when switching between Adult and Neo mode This change will also not be retained across a power cycle BP Test Mode Chapter 3 Page 17 AccuSim BP OPERATING MANUAL Amp Amplitude adjustment is an advanced feature and generally should not be needed for most applications The default value of 100 is appropriate for most normal Adult and Neo cuff sizes This adjustment might be needed when using cuffs that are significantly larger or smaller Typically this may be
