What impact has the transition from analogue to digital recording had on polysomnography?

The transition from analogue to digital recording in polysomnography has significantly increased the ability to record and display multiple bits of information simultaneously. Digital systems allow for the capture of complex data sets from various physiological signals, such as EEG, EOG, EMG, and others, in a precise and organized manner. This advancement enables technicians to analyze more detailed and varied data points at once, thus providing a comprehensive view of a patient's sleep patterns and associated disorders.

In contrast to analogue systems, which were limited in the number of channels they could record and often had issues with data quality and preservation, digital systems can handle a larger volume of information without compromising fidelity. The visualization of this data is also enhanced in digital formats, which means clinicians can assess and interpret the results more efficiently and accurately. This capability ultimately leads to better patient diagnosis and treatment for sleep conditions.
