Actigraphy is a way of measuring human activity and in particular wake/sleep cycles. An actigraph is a small device usually worn on the patient’s wrist and measures movement. It can give a good indication of wake/sleep patterns.

Home Sleep Test

Home sleep testing provides a board-certified sleep medicine physician with the information he or she needs to screen for sleep disorders. Home sleep testing allows you to sleep at home wearing equipment that collects information about how you breathe during sleep. You will usually set up the testing equipment yourself.

There are a variety of home sleep testing devices that have different sensors and equipment. All home sleep test devices measure your breathing and blood oxygen level. Some may also measure your heart rate or other information about your body. Home sleep testing is primarily used to diagnose obstructive sleep apnea.

A sleep specialist may recommend home sleep testing if:

  • It is highly likely that you have moderate to severe obstructive sleep apnea.
  • You have no significant medical conditions other than the suspected obstructive sleep apnea.
  • You should NOT have a home sleep test if:
    • You do not have a high risk of obstructive sleep apnea.
    • The physician suspects you may have another sleep disorder.
    • You have certain medical conditions including pulmonary diseases, neuromuscular diseases, or congestive heart failure.
    • In these cases, your sleep specialist may recommend an in-lab sleep study instead of a home sleep study. An in-lab sleep study provides the most complete evaluation of your sleep. (Source


Oximetry is a test that allows the measuring of a patient’s blood saturation levels. This is a non-invasive test. A sensor is placed on the patient’s finger and wrist and is worn overnight. This device records a patient’s blood oxygen levels at night to determine if a patient is experiences significant drops in blood oxygen levels, which can be an indication of sleep apnea.
