Home sleep testing is a polysomnogram that provides a board certified sleep medicine physician with the information they need to diagnose obstructive sleep apnea. This is a procedure that measures important bodily functions during sleep. A reduced number of sensors are used to take these measurements from home versus in a sleep center environment, and none of the sensors cause significant discomfort.
Home sleep testing allows you to sleep at home wearing this equipment and collects information about how you breathe during sleep. You will have an appointment to set up the testing equipment in the sleep center during the day to show you how to put these sensors on yourself.
The bodily functions that are measured at home are:
- Breathing - a sensor is placed below your nose that measures airflow; elastic bands are placed around your chest and abdomen to sense when you’re making breathing efforts.
- Oxygen level - a finger clip measures the amount of oxygen in your blood.
- Snoring - a small microphone or vibration sensor records snoring sounds.
- Heart rate and rhythm - electrodes on your chest record your heartbeat (EKG).
Typically, you would come to the sleep center several hours before bedtime. The sleep center consists of a suite of rooms and includes a control room and several private sleeping rooms with a bathroom and a shower. The technologist sets you up and monitors the signals from an adjoining room to ensure a high quality recording. Within a few days a sleep physician reviews your study and a report is sent to your physician.
