Technologists work in sleep centers, conducting overnight monitoring of patients’ sleep patterns, brain waves, heart rate, oxygen levels, and other physiological parameters. By assisting with the accurate diagnosis of sleep conditions such as sleep apnea, narcolepsy, and restless leg syndrome, RPSGTs play a crucial role in improving patients' overall health and well-being.
