Home sleep study guide

A home sleep study measures your breathing, oxygen and pulse overnight in your own bed - the standard first test for suspected sleep apnoea - and knowing what to expect makes for a better recording and a faster answer.

Key facts

The essentials at a glance.

The symptoms to recognise, when to seek help, which specialist to see, and what treatment usually involves.

  • The kit: a nasal cannula for airflow, chest and abdominal bands for effort, a finger probe for oxygen and pulse - fitted in minutes following simple instructions

  • Sleep as normally as possible: usual bedtime, usual position, avoid alcohol that night unless it is a nightly norm, and note the night in a brief diary

  • Results are reported as the apnoea-hypopnoea index (AHI): under 5 normal, 5-15 mild, 15-30 moderate, over 30 severe

  • Specialist: a consultant in sleep medicine interprets results in context - a single imperfect night or a normal-looking result despite strong symptoms may justify a repeat or an upgraded laboratory study

Understanding the condition

What it is and what happens next.

What causes it, how it is diagnosed, and the treatment routes available in the UK.

What it is and how it feels

The home respiratory polygraph has made sleep apnoea diagnosis quick and comfortable: you collect or receive the device, attach the sensors before bed - cannula under the nose, elastic bands around chest and stomach, probe on a finger - press record, and sleep in your own bed, which for many people yields a truer picture than a wired night in a strange laboratory. The device logs every dip in airflow, every straining breath against a closed throat and every fall in oxygen, and software plus a physiologist's review converts the night into an apnoea-hypopnoea index and oxygen profile that grade the condition from absent to severe.

Diagnosis and treatment routes

Practical points improve the result: follow your normal routine, avoid unaccustomed alcohol or sedatives, secure the cannula with the tape provided if you toss and turn, and record roughly when you slept and woke - the analysis needs sleep time, and an honest bad night is worth reporting since indices are diluted by hours awake. Interpretation belongs with a specialist because context is everything: a moderate AHI in a sleepy lorry driver and the same number in an asymptomatic snorer lead to different conversations, home studies can underestimate severity, and strong symptoms with an unconvincing result warrant repeat testing or full polysomnography rather than dismissal. From a good study, the route to treatment - CPAP, an oral device or conservative measures - is immediate. In many parts of the UK, routine NHS referrals for this kind of problem currently take 20-45+ weeks, whereas an initial appointment with a private consultant is typically available within around two weeks.

Seeing a specialist
