Description:

The course introduces students to biomedical environment, patient care instrumentation, reasons why biomedical engineering technology is a regulated profession, and safety standards (CSA, AAMI, IEC and Electric Safety). Signals form the basis of instrumentation and the nature of these and their relationship to noise and interference forms the basis of instrument design from component selection to system level. Being electronic instruments medical devises must have an electrical signal input. This is accomplished by using electrodes to inter-phase patient and instrument. A transducer converts nonelectrical physical events such as force and temperature to an analog electrical signal. Amplifiers are used to process analog electrical signals. Cardiac muscle cells generate action potentials that create electrical currents that are spread throughout the body creating potential differences between any two sites and the resultant ECG waveform forms the basis of diagnosing cardiovascular disease. 

Measurement of physiological fluid pressures is of considerable interest to biomedical field. The most common pressure measurement is for arterial blood pressure that is routinely monitored in ICU. The respiratory system is essential to survival and provides the means for acquiring oxygen and eliminating carbon dioxide. The gas laws form the basis for understanding respiratory function and measurement instruments.
