BMS239 Clinical Measurement (8)

This subject covers topics particularly relevant to those working in Clinical Science Laboratories, including Infection Control and the basic electronic principles and concepts by which bioinstruments work. This information is applied in the context of Spirometric measurement; its technical considerations, performance criteria and interpretation. The subject runs by distance education servicing a number of programs that involve patient testing and respiratory evaluation. It is taught through Interact and Online Meetings with a scaffolded assessment plan to support student learning and experience.


Session 1 (30)
Wagga Wagga Campus

Continuing students should consult the SAL for current offering details: BMS239. Where differences exist between the Handbook and the SAL, the SAL should be taken as containing the correct subject offering details.
