Bioimpedance measurements.

Explain how the electric impedance of tissues (bioimpedance) is formed and describe how it can
be modelled.

Describe and evaluate bioimpedance measurement systems, in general

Describe and evaluate impedance cardiography method, in particular.

ECG and EEG are basic physiological measurement. Explain the following concepts and how they
differ in ECG and EEG. The answer can be list-type, ECG and EEG topic side-by-side.

The standard lead systems used in ECG and EEG.

Noise coupling and elimination in ECG and EEG recordings.

To measure and assess physiological systems there are usually several alternative measurement
methods available.

Compare the static and dynamic pulmonary function tests.

Compare alternative methods for continuous arterial blood pressure recording and monitoring
methods

Explain briefly in few sentences the following measurement devices (what and how is measured).

Thermodilution method.
Evoked response measurement.
Pulse oximeter.

Cardiac event monitoring.

Monitoring the depth of anesthesia.
