A maximum frequency detector for Doppler blood velocimeters
Abstract:
The clinical information available from ultrasonic Doppler blood velocimeters may be analysed in several ways, spectral analysis probably being the best. This is, however, a relatively expensive technique when compared with the cost of commerically available Doppler velocimeters. A large part of the diagnostic information present can be obtained from the maximum blood velocity in the vessel at any one time. A relatively inexpensive analogue method of extracting this information from the Doppler signal is described, and the preliminary results obtained on signals derived from peripheral arteries are discussed.

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...
