A home sleep apnea test is a sleep study tool that is used for the diagnosis of obstructive sleep apnea. The device is about the size of a cell phone and it is worn while you are sleeping at home in your own bed. The device measures:

• Nasal and Oral Airflow by a small sensor that is worn under the nose – similar to a nasal cannula.
• Respiratory Effort via an elastic belt band that are placed across the chest.
• Oxygen levels and heart rate via an oximeter finger probe that is worn on the fingertip.

After a night of sleep, the device is returned to the hospital and the information recorded is evaluated by a physician that specializes in sleep disorders.
