Home Sleep Study
Done in the comfort of your own home, a home sleep apnea test is a sleep study tool that is used for the diagnosis of obstructive sleep apnea. Most HST devices are portable – about the size of a telephone handset and measures the following biologic parameters:
Nasal and Oral Airflow – by thin wire that is taped by the nose and mouth – some sensors look like an oxygen cannula.
Respiratory Effort – by elastic belt bands that are placed across the chest and abdomen.
Oxymeter Finger Probe – a small clip-like device that attaches to the finger tip and emits a red light that assists in the evaluation of oxygen levels in the blood while sleeping.
Your sleep physician may order a in home sleep study if they suspects you may have obstructive sleep apnea. The home sleep is applied by the above mentioned sensors to the body before sleep time and sleeps with the equipment for 1 – 3 nights. The equipment is returned to the diagnostic service company where the data is downloaded and processed for interpretation by a sleep physician.
Once the data is interpreted by a sleep physician, a diagnostic interpretation report is sent back to the ordering physician who discusses the results of the home sleep testing.
