Thermodilution sensor for blood flow measurement in a blood vessel. Unlike the thermodilution sensors, electromagnetic flowmeters measure the instantaneous flow of blood. Electromagnetic flowmeter where all three vectors are orthogonal to each other. Ultrasonic Flowmeters Sound is a pressure waveform. It can travel in all media, including the tissue and blood.
Most ultrasonic devices transmit and receive using the same transducer.
Doppler ultrasound for blood velocity measurements. In this experiment we will use a very basic ultrasonic Doppler monitor. This device has two crystals, which allow operations at 5 MHz and 7 MHz. Device also provides audio feedback that can be used during transducer placement. Connect ECG electrodes in Lead 2 configuration.
