Page 3: User's Manual 1. Introduction
The NIBP250 noninvasive blood pressure monitor is a stand-alone device for measuring the blood pressure of small animals. The NIBP250 has a convenient touch screen LCD user interface and includes a built-in Tail Cuff Sensor pump that automatically inflates the cuff to occlude the blood vessels in the tail of a rat or similar small animal. -

NIBP250 User’s Guide 2.4. Main Screen The touch-sensitive Main Screen (see Figure 4) controls all operational and setup functions. All buttons on the right of the screen are also touch-sensitive. For a full explanation of onscreen buttons, see Table 2 on page 6. -
Page 7: Measurement Analysis View
Figure 5: Analysis View If the “Peak by peak” option is selected, the NIBP250 automatically detects the peaks of the pulse signal and marks them with white crosses as seen in Figure 5. Touching anywhere on the plotting will bring up a cursor. -

Noninvasive Blood Pressure Monitoring System After setting the Date/Time Properties, click “OK” at the top right of the window to accept the new settings. To discard settings without saving changes, click the “X” button. The “Pulse gain” and the “Cut Off Pressure” are adjusted by moving the sliders left or right. Click OK to accept any modified settings. -
Page 10: Usage
In a standard cuff using the "auscultatory" method, the diastolic pressure is determined by the last pulse detected as the signal falls back to baseline. In the NIBP250, which uses the "oscillometric" method, the diastolic pressure is aligned with the peak pulse detected. -
Page 11: Working With Saved Results
Figure 12: Location of Systolic and Diastolic Pressures The NIBP250’s automated peak detection system marks the peak of each pulse with a white cross, and is enabled by selecting the "Peak by peak" option on the Main Screen. This feature makes it easier to identify the individual pulses. -
Page 12: Result File
3.6. Result File After measurements are performed, the pressure and pulse signals (including the analysis results) can be saved to NIBP internal memory, SD Card or USB Memory. If you insert any external memory NIBP250 uses it instead of its internal storage. -
Page 13: Calibration
To start a measurement using the trigger, Enable the “Trigger Input option” checkbox in the Options Tab (see 2.5.2. Options) and then press the “Start” button. NIBP250 will wait until the trigger is initiated before acquiring the measurement . To trigger the measurement the trigger input signal must be set low. -
