After an initial consultation with your physician or a sleep specialist, you may be referred for a sleep study. The medical term for this study is Polysomnogram, which is a non-invasive, pain-free procedure that usually requires spending a night or two in a sleep facility. During a polysomnogram, a sleep technologist records multiple biological functions during sleep, such as brain wave activity, eye movement, muscle tone, heart rhythm and breathing via electrodes and monitors placed on the head, chest and legs.
After a full night’s sleep is recorded, the data will be tabulated by a technologist and presented to a physician for interpretation. Depending on the physician’s orders, patients may be given therapy during the course of the study, which may include medication, oxygen or a device called continuous positive airway pressure therapy or CPAP.
