The Fluke Biomedical ProSim 8 provides pre-sets for the six most commonly used parameters:
Electrocardiograph (ECG)
Non-invasive blood pressure (NIBP)
Invasive blood pressure (IBP)
Oxygen saturation (SpO2)
Respiration
Temperature
When initially powered-on, the ProSim 8 defaults to a “Normal” pre-set for these six values, and the user can select a “Hypertensive” as well as a “Hypotensive” pre-set. In terms of time, NIBP is unique among these parameters since it requires the unit under test (UUT) to pressurize a cuff or reservoir, then slowly decrease the pressure while making a determination of systolic, diastolic, and mean arterial pressures. On its initial NIBP cycle, the typical monitor will pressurize to160 mmHg. If the simulated systolic pressure is 120 mmHg, the UUT will successfully detect that systolic value, and store it in memory for use in the next NIBP cycle. On starting the next cycle, most NIBP monitors will pump up to a value slightly above the last systolic value, on the premise that the patient’s systolic pressure likely hasn’t increased significantly since the last cycle. However, if the next simulated systolic is in the “Hypertensive” pre-set, e.g. 200 mmHg, the UUT will “look” for the lower (“Normal”) systolic. Because it will detect pulsations immediately, its software will determine that the new systolic is higher, and command a new NIBP cycle. In some monitors the second cycle may still not find the new systolic value, requiring a third attempt. All of this will require additional time, so the proper sequence of test pre-sets will make a big difference in the total time taken for a thorough functional test.
