1.What is sleep monitoring? Sleep monitoring is a monitoring that takes place overnight and provides vital vital information about your sleep health by collecting and analyzing a variety of signals from your body, including brain waves, electrocardiogram, muscle activity, eye movements, whistling movements and blood oxygen levels. These signals are obtained through small sensors attached to your head, face and body, and you will not feel any special discomfort. 2. Why is sleep monitoring important? Sleep monitoring allows physicians to evaluate conditions that occur only during sleep and that cannot be detected during routine in-office examinations. Sleep monitoring helps identify the multiple causes of sleep-related disorders, develop effective treatment, and evaluate efficacy. 3.What should I pay attention to on the day of sleep monitoring? Activities or diet that affect sleep can lead to discrepancies between the monitoring results and the real situation. The oil and keratin of skin hairs may affect signal acquisition, so: please do not take a nap; wash your hair and cut excessive nose hairs; if possible, men please shave your beard; consume less water and liquid food on the night of the examination; do not drink alcohol, tea and caffeinated beverages; do not take sedative or sleeping pills. You can bring your own pajama pants and, if possible, bedding such as pillows and sheets that you usually like to use very much, and children can bring toys that they usually like to cuddle and fall asleep with, etc. In short, try to make yourself as comfortable as possible to the state of sleeping at home. 4.What are the steps of sleep monitoring? It takes about 30-60 minutes for the sleep monitor to attach small electrode pieces or sensor paper to specific locations on your head, chest, abdomen and legs. The monitor will monitor and be on duty in an adjacent room. You can contact through the whistler if you have any problems. 5. Why is it important to fill out the sleep questionnaire carefully? You will usually be asked to fill out questionnaires about your symptoms, medical history, sleep and lifestyle habits before the sleep monitoring. Sleep whistling disorders are a group of chronic diseases that may lead to damage to the heart, brain, kidneys, lungs and other organs of the body if left untreated, and require timely treatment and regular review. The questionnaire is directly related to the diagnosis, evaluation and selection of appropriate treatment for your disease, and is very helpful for long-term observation and continuous treatment of your disease, so please fill it out carefully.
