Principle
The Doppler effect is used with ultrasonic waves to investigate the laws of stationary laminar flow, which underlie a great many technical applications. The liquid under investigation flows through a circuit of tubing. Particular aspects to be studied experimentally ...
Principle and tasks
To prepare a plot of blood pressure measurement and to read the values of systolic and diastolic blood pressure.
What you can learn about
Didactical blood pressure measurement system for wireless data transfer of measurement data from test person to computer, thereby permitting flexible and mobile experimental setup.
Tasks
To prepare a plot of blood p ...
To prepare a curve showing the change in skin temperature during smoking. To discuss different curves depending on the smoking habits of the test person.
Principle and exercises
This experiment records how skin temperature changes with time when someone is smoking with the help of a temperature sensor and the Cobra3 interface. How the temperature curve differs should be discussed with reference to the tested persons ...
Cigarette consumption influences the diameter and therefore the circulation of the peripheral blood vessels. This experiment studies the change of the finger temperature during smoking.
This set-up shows how blood flow studies are performed using Doppler ultrasound (Doppler sonograph). On a realistic arm dummy, the differences between continuous (venous) and pulsating (arterial) flow are shown as well as the difference in flow through a normal bloo ...
Using a simple heart model, the wall motion is recorded with the ultrasonic time motion method (M-mode or also TM-mode). The heart rate and the cardiac output (CO) are determined from the recorded TM-mode curve.
