Principle
The heart is a hollow, muscular organ that comprises several secondary muscles. These secondary muscles contract and relax successively, thus pumping the blood through the heart. These muscle activities can be measured electrically as a whole at the ...
This blood pressure cuff is used to measure blood pressure. Included in the data transferred to the computer are both the pressure fluctuations generated by the beating of the pulse and the fall ...
An electrocardiogram (ECG) enables you to observe the regular sequence of heart contractions as well as to determine your heart frequency by determining the interval between two heart contractions. In a second experiment, you will measure the heart f ...
An electrocardiogram (ECG) can record the sum of the electrical activities of all of the heart muscle fibres. Under stress, cardiac activity increases in order to maintain the stability of the cardiovascular system. The heart contraction cannot be con ...
Principle and tasks
To record an electrocardiogram (ECG) between the left leg and the right and left arm (lead II according to Einthoven). To relate the ECG segments to the course of heart contraction (P wave, P-Q segment, QRS complex, T wave).
What you can learn a ...
Principle and tasks:
Cardiac and vascular sonic measurement at different locations of the circulatory system. Measurement of the pulse rate at different levels of athletic loading.
What you can learn about:
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 pressure measurement and to r ...
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.
How can our body temperature be regulated? This experiment shows why we sweat in summer and wear gloves in winter.
