What it means
A sleep study records your body's functions while you sleep to diagnose sleep disorders such as sleep apnea, insomnia, or narcolepsy. You will spend the night at a sleep center where sensors are attached to your scalp, face, chest, and legs to monitor brain waves, eye movements, heart rate, oxygen levels, airflow, and body movements. The sensors are attached with a mild paste and are not painful. A technician monitors you from another room. You should bring comfortable pajamas and any medications you normally take. An at-home sleep test is a simpler alternative sometimes used to diagnose sleep apnea. Results are usually available within one to two weeks after a sleep specialist reviews the data.
How to say it
Sentences a patient might use with a doctor, nurse, pharmacist, or insurer:
Can I take my usual sleep medications the night of the sleep study?
¿Puedo tomar mis medicamentos habituales para dormir la noche del estudio del sueño?
Will I be able to sleep normally with all the sensors attached during the study?
¿Podré dormir con normalidad con todos los sensores puestos durante el estudio?
Is there an at-home option instead of spending the night at a sleep center?
¿Hay una opción para hacer el estudio en casa en lugar de pasar la noche en el centro?
