Abstract:
Noninvasive blood pressure (NIBP) is one of the most common vital signs monitored by today's bedside and transport monitors. A variety of NIBP measurement methods has been used in these monitors. Some of the methods provide intermittent measurements over a period of time, while others provide continuous measurement on a beat-to-beat basis. Most of the monitors provide for on-demand measurement as well as automatic measurement at user-selected intervals. The measurement accuracy of an NIBP monitor is typically established by clinical evaluation. Generally safe and easy to use, NIBP monitors play a very important role in patient care.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
