Module overview
Medical Devices lie at the heart of all measurements performed by Cardiac Physiologists and correct use is therefore essential to providing a high quality service.
This module will introduce you to the principles of operation of common devices that you will use in your practice. You will learn how to measure their performance and determine if it is acceptable for clinical use. You will discuss how performance can be optimised through calibration, quality assurance and standard operating procedures and consider risks.
This module has a strong emphasis on application to practice, taking simple scientific concepts and translating them to the particular device being studied.
