| Abstract： |
Sleep technology has been around for decades, yet sleep technology today is all different from what it has been in the old days. And it is still developing, alongside with the evolving needs of the growing discipline of sleep medicine.
Polysomnography is considered the gold standard for the evaluation of sleep disorders. With advancement in modern computer technology, digital polysomnographic systems nowadays are equipped with powerful recording and analysis hardware and software. Signals are good and may resemble those analog ones, with flexible multiple channel selection and display and allowing change of settings during recording or review. Data archive, restore and storage are also simple and easy. However, in many countries where sleep medicine is relatively new, there is no proper training on sleep medicine and technology provided to technical staff; they may only have weak knowledge on the basic issues, such as the need and use of changes in equipment settings and scoring rules that may be revised annually to meet update clinical and research findings of sleep disorders. Some centers do not perform manual scoring but rely on computer scores.
From time to time there may be difficulties during sleep studies. There is an increasing complicated patient population with comorbid sleep and medical problems, and some patients may have unstable mental condition and be potentially threatening. Physicians and technicians need to be well trained for ensuring patient and staff safety, and for quality sleep studies and their reliable interpretation.
In this lecture, issues about polysomnography will be discussed, from its development, classification, instrumentation, scoring, to difficulties and safety concerns, interpretation, training needs of staff, and quality assurance. Participants will be able to recognize the essential elements of polysomnography.
