What is Home Sleep Testing?

Home Sleep Testing (HST) is the objective assessment of an individual’s sleep quality and quantity, carried out in their own home.

Historically HST was performed exclusively in a hospital. Today, with technological advances, it is possible (and some consider preferrable) for sleep tests to be performed at home.

How home sleep testing works

The individual wears the HST device overnight, most commonly on a belt around their chest (and sometime stomach too), with various additional sensors attached, including those that monitor airflow through their nose and the oxygen level in their blood.

Upon waking in the morning, the device is removed and returned to the hospital, so that the recorded data can be assessed. Commonly, in conjunction with a comprehensive paper questionnaire (about the individual’s reported sleepiness and medical history etc.).

The data

The data from the HST device is then ‘scored’ using a software program and a report created. This (and when necessary the raw data) is then reviewed by a Sleep Technician.

Then a Consultant Physician will review the software report and the Sleep Tech’s assessment and provide their professional opinion/diagnosis.

The rules

The rules around home sleep testing vary. In some countries dependent upon the number of parameters assessed overnight (machine sophistication) and the completeness of the questionnaire, the report is sufficient for a diagnosis of obstructive sleep apnoea, while in other countries home sleep testing is used, in perhaps a less formal way, to identify those that require further investigation in a hospital or sleep laboratory.
