A realistic arm model is used to show the differences between continuously (venous) and pulsatile (arterial) flow and between normal blood flow and a stenosis. |

For blood pressure measurements with Sensor-CASSY or UMIP, the pressure variations which are caused by the pulse waves are transmitted by the arm collar and measured together with the falling pressure in the arm collar. . |

For measurement of the electrical processes at the heart muscle (ECG, electrocardiogram) or skeletal muscles (EMG, electromyogram). The tension of the muscles is recorded with self-adhesive silver/silver chloride electrodes. |

For measurement of the electrical conductance of the skin with CASSY. The degree of skin conductance provides information as to the level of "emotional excitement" (stress) of the test person and provides information on the the mechanisms of the stress reaction. The electrodes are attached to the finger tips by way of Velcro fastening bands and are electrically isolated from the measurement input of the CASSY. |
