| DESCRIPTION | This study-unit provides an in-depth exploration of the fundamental principles and clinical applications of biomedical signal acquisition, processing, and analysis. Students will learn to identify and describe various physiological signal generators, evoked responses, and brainstem reflexes, and understand the procedures for their stimulation, acquisition, and analysis. The students will be introduced to electroencephalography (EEG), evoked potentials (EPs) and polysomnography (PSG), and to their clinical applications focusing on the recording processes, electrode placement, and signal interpretation in various clinical settings, including neurology, anaesthesia, and sleep studies. By the end of the study-unit, students will be able to classify physiological and artefactual signals, mitigate interference, and apply these techniques effectively in a clinical environment. Study-Unit Aims: - To ensure that students are able to identify various physiological signal source generators and their acquisition; - To ensure that students are able to analyse and review the acquired signals, and identify any artefacts; - To ensure that students are able to identify dangers related the signal acquisition process and ensure patient safety; - Describe the use of and operate medical instrumentation to record electroencephalography (EEG), evoked potentials (EPs) and polysomnography (PSG) in a clinical context; - To make students aware of issues concerning Consent & Confidentiality and on how to Deal with Nervous Patients. Learning Outcomes: 1. Knowledge & Understanding: By the end of the study-unit the student will be able to: - Identify: 鈥� Various physiological signal source generators, such as: the dipole model of a nerve cell; the pyramidal cell; signals generated by the heart, retina and cochlea. 鈥� Various evoked responses, such as: visual, motor, somatosensory and brainstem auditory evoked potentials; cognitive negative variation. 鈥� Various brainstem reflexes, such as: the blink, larygneal adductor and trigeminocardiac reflex. 鈥� Muscle responses as used in nerve conduction studies, including: M, F and H waves. This includes identifying the various factors affecting their characteristics. - Identify, describe and implement the procedure for the generation/stimulation of the above physiological signal generators and their acquisition processes. This includes describing: (a) the various recording/stimulation electrodes; (b) the various non-physiological factors affecting signal recording; (c) the skin preparation, calibration, and technical characteristics of the recording process, including the data archiving process; (d) the different types of stimulation, related configurations, and their implementation in a clinical context; (e) the required stimulus parameters to mitigate dangers related to the stimulation of anatomical structures. - Describe the use of and operate medical instrumentation to record electroencephalography (EEG) in the clinical context and EEG monitoring in the laboratory, ITU, operating theatre, and ambulatory monitoring; - Describe the use of and operate medical instrumentation to record evoked potentials in the clinical context. This includes: auditory, somatosensory and visual evoked potentials, electroretinography, and electrooculography; - Describe the use of and operate medical instrumentation to record polysomnography in a clinical context; - Identify issues concerning Consent & Confidentiality and explain how to deal with nervous patients. 2. Skills: By the end of the study-unit the student will be able to: - Perform the various physiological signal acquisition and apply the required stimulation as applicable; - Operate and configure the equipment depending on the physiological signal being acquired; - Identify artifacts within the recorded signals and apply the necessary procedures to mitigate the interference; - Identify potential risks to patients and apply necessary mitigation procedures; - Describe the clinical analysis of electroencephalography (EEG), evoked potentials (EPs) and polysomnography (PSG) signals.
