Level 3 Sleep Study

A convenient home sleep test for diagnosing sleep apnoea. Evaluate your breathing patterns, oxygen levels and sleep-related respiratory disturbances — without an overnight stay in a sleep laboratory.

What is a Level 3 sleep study?

Diagnose sleep apnoea, from home.

Do you snore loudly at night? Do you wake up feeling tired even after a full night's sleep, or has your partner noticed pauses in your breathing while sleeping? These symptoms may indicate Obstructive Sleep Apnoea (OSA), one of the most common yet underdiagnosed sleep disorders.

A Level 3 Sleep Study is a portable sleep test performed in the comfort of your own home, using specialised monitoring equipment to record key breathing and oxygen-related parameters while you sleep. Unlike a Level 1 study performed in a sleep laboratory, it focuses specifically on detecting sleep-related breathing disorders such as Obstructive Sleep Apnoea.

At Healthy Chest & Sleep Clinic, Dr. Vishal Sharma offers Level 3 Sleep Studies as part of a comprehensive sleep medicine program aimed at diagnosing sleep-related breathing disorders quickly, comfortably and accurately.

Who should consider it?

Signs that point to a sleep study.

A Level 3 Sleep Study may be recommended if you experience any of the following warning signs.

Loud snoring

Persistent snoring can be an early warning sign of airway obstruction during sleep.

Excessive daytime sleepiness

Feeling tired, sleepy or fatigued despite adequate sleep duration.

Witnessed breathing pauses

A partner or family member notices that you stop breathing during sleep.

Morning headaches

Frequent headaches shortly after waking.

Poor sleep quality

Waking multiple times during the night or feeling unrefreshed.

Difficulty concentrating

Poor sleep quality often affects focus, memory and productivity.

Resistant high blood pressure

Sleep apnoea is a common but overlooked contributor to hypertension.

Obesity or weight gain

Overweight patients are at higher risk of sleep-disordered breathing.

What it measures

Focused on your breathing.

The test focuses on breathing-related parameters to determine whether sleep-disordered breathing is present and how severe it may be.

Airflow

Measures the movement of air through the nose and mouth.

Respiratory effort

Evaluates the effort your body makes to breathe during sleep.

Oxygen saturation

Tracks oxygen levels throughout the night.

Heart rate

Monitors cardiovascular activity during sleep.

Body position

Assesses whether breathing disturbances worsen in certain positions.

Apnoea & hypopnoea events

Detects episodes of reduced or interrupted breathing.

Conditions diagnosed

What a Level 3 study can reveal.

Obstructive Sleep Apnoea (OSA)

Sleep-related breathing disorders

Conditions affecting normal breathing during sleep.

Nocturnal oxygen desaturation

Episodes of low oxygen levels occurring while sleeping.

Snoring with airway obstruction

Assessment of whether snoring is linked to significant breathing abnormalities.

Level 3 Sleep Study

Performed at home, primarily evaluating breathing, airflow, oxygen saturation and respiratory events.

Best for suspected OSA

Most suitable for patients with suspected Obstructive Sleep Apnoea.
