A home sleep test (HST) is a sleep study done at home that is used for the diagnosis of obstructive sleep apnea. Most HST devices are portable – about the size of a telephone handset. Home sleep testing is also called ‘Unattended Sleep Study’.
They usually measure 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.
- Oximeter 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.
