Home Sleep Apnea Screening
A home sleep apnea test is an overnight test used to help investigate suspected obstructive sleep apnea.
Sleep Apnea, Polysomnography and Sleep Studies
Assessing sleep-related breathing and other sleep concerns.
Sleep apnea is a sleep disorder in which breathing repeatedly stops, starts or becomes too shallow during sleep. A person may not realise this is happening. In many cases, a partner or family member first notices loud snoring, pauses in breathing, gasping or choking. Sleep apnea can affect several areas of health and daily functioning.

When Breathing Repeatedly Reduces or Stops During Sleep
Sleep apnea is a sleep disorder in which breathing repeatedly stops, starts or becomes too shallow during sleep. A person may not realise this is happening. In many cases, a partner or family member first notices loud snoring, pauses in breathing, gasping or choking. Sleep apnea can affect several areas of health and daily functioning.
Obstructive Sleep Apnea
Obstructive Sleep Apnea (OSA) occurs when the upper airway repeatedly narrows or closes during sleep. The person continuously tries to breathe, but airflow is reduced or temporarily blocked. The airway can reopen, causing loud gasps for air. Repeated interruptions may disrupt sleep architecture.
Central Sleep Apnea
Central Sleep Apnea differs from OSA. Breathing is disrupted because the brain temporarily does not send the expected signals to the muscles involved in breathing. Central Sleep Apnea is a more severe form of sleep apnea. A sleep study may form part of the investigation.
Possible Warning Signs
Possible Warning Signs
Loud snoring
Breathing pauses witnessed by another person
Gasping, snorting or choking
Restless sleep or frequent waking
Waking with a dry mouth
Frequent night-time urination
Excessive daytime tiredness
Morning headaches
Difficulty concentrating or forgetfulness
Irritability or mood changes
Reduced alertness
These symptoms are associated with sleep apnea but are not specific to it. Snoring alone does not confirm sleep apnea, and not every person with sleep apnea snores.
Why Assessment Matters
Why Assessment Matters
Untreated sleep apnea is associated with impaired daytime alertness and may contribute to broader health risks. Patients experiencing severe sleepiness should be especially cautious when driving or operating machinery and should seek medical advice.
What the study may record
Airflow through the nose, breathing effort, blood oxygen levels, pulse or heart rate, snoring, body position, sleep stages and hypoxic burden.
Polysomnography
Polysomnography is a more comprehensive overnight sleep study that may record brain waves, eye movements, muscle activity, heart rate, breathing, blood oxygen levels, leg movements, chin and leg muscle activity and video and audio, where applicable.
How Is Sleep Apnea Managed?
How Is Sleep Apnea Managed?
Management depends on the diagnosis, severity, symptoms and individual patient factors. Possible approaches may include:
- Weight management where clinically appropriate
- Reducing alcohol consumption
- Stopping smoking
- Positional therapy
- Continuous Positive Airway Pressure (CPAP)
- Mandibular advancement devices
- Treatment of nasal obstruction
- Management of underlying medical conditions
CPAP
A CPAP machine delivers pressurised air through a mask to help prevent the airway from collapsing during sleep.
Sleep Health Check
Sleep Health Check
I snore loudly most nights.
Someone has witnessed me stop breathing while asleep.
I wake gasping, snorting or choking.
I regularly wake with a headache.
I wake with a dry mouth or sore throat.
I feel unrefreshed after a sufficient number of hours of sleep.
I struggle to stay awake during quiet daytime activities.
I have difficulty concentrating.
I wake repeatedly during the night.
I have high blood pressure.
My sleepiness affects my work or driving.
None of the above.
One or more symptoms may justify discussing your sleep with a healthcare professional. This checklist does not diagnose sleep apnea or determine its severity.
