The industry-standard technique of oscillometry is used for non-invasively measuring systolic blood pressure (SBP) and diastolic blood pressure (DBP). The method is based on the measurement of oscillations through the occluding cuff which is placed on the patient’s upper arm during an NIBP measurement. The pulsatile oscillations are measured using a pressure transducer and then digitized using a microprocessor. The NIBP algorithm used the digitized oscillations and applied cuff pressure as input to an empirical model to calculate SBP and DBP.
Blood pressure measurements can be affected by the patient’s position and/or physiological condition.
The ViSi Mobile has three BP modes: one-time, interval, and continuous. The Monitor will automatically default to NIBP mode depending on which sensors are connected. You only need to select an NIBP mode if you want to change the default.
Select Menu and choose the BP icon (second icon on top row) to change the BP mode if the icon does not reflect the mode you want to be in.
On initial entry into the BP Management screen, the default blood pressure mode will automatically be selected. The default mode is dependent on the connected sensors and the cNIBP license. As long as the NIBP Module is plugged in, a manual NIBP measurement can be initiated at any time. When the NIBP mode is set to Automatic, if the timing of the manual measurement overlaps with the automatic measurement interval, then that automatic measurement is skipped; otherwise, the automatic measurement occurs as scheduled.
When obtaining any BP, remember that the displayed icon when you connect the cuff module displays what type of BP will be taken.
