What happens during a sleep study?

During a sleep study, also known as a polysomnogram, several bodily functions are monitored to evaluate sleep patterns and diagnose sleep disorders. The process typically takes place overnight in a sleep center. Electrodes are placed on the scalp, face, chest, and legs to measure brain waves, eye movements, heart rate, breathing, and muscle activity. This information helps specialists identify sleep stages, disruptions, and abnormal breathing patterns. Additional sensors may be used to record oxygen levels, body position, and snoring. Qualified technicians monitor the recording equipment throughout the night, ensuring accuracy and comfort for the patient. After the study, the collected data is analyzed by a sleep medicine physician who will provide a comprehensive report and recommend appropriate treatment options if necessary.
