Home Sleep Study in Hyderabad: What to Expect, What It Measures, and What Happens Next
One Night in Your Own Bed. Report Read by Our Team in 48–72 Hours.
For most suspected sleep apnea, you do not need to sleep in a hospital. You sleep in your own bed, with a small device strapped to your chest and a soft sensor on one finger. The next morning you return the device, and within 48 to 72 hours your report is read by our specialist team and discussed with you in a consultation.

This page walks you through every step: what the device measures, how the night goes, what the numbers in your report mean, and how we decide what happens next.
What a home sleep study is, and how it differs from a hospital sleep study
A home sleep study tests for sleep apnea using a small device, in your own bed, over a single night. It is the standard first-line diagnostic test for adults with suspected moderate-to-severe obstructive sleep apnea, and it is supported by the American Academy of Sleep Medicine clinical practice guideline (Kapur et al., 2017).
The hospital version is called polysomnography (the in-lab version of a sleep study, with more sensors, including brainwave electrodes that score sleep stages and REM). Home tests are a Level 3 study. They record breathing, oxygen, and effort, but not brainwaves. For uncomplicated sleep apnea, that is enough.
Home testing is not a downgrade. It is the right test for the right patient. Where it is not appropriate, we say so and arrange an in-lab study instead.
What the test actually measures
Four signals do the diagnostic work.
| Signal | Sensor location | What it tells us |
|---|---|---|
| Airflow | Soft cannula at the nose | Whether you stopped or slowed breathing |
| Respiratory effort | Belt around chest, belt around belly | Whether your chest and belly are still trying to breathe during a pause |
| SpO2 (oxygen saturation) | Soft clip on a finger | How far oxygen drops during each event |
| Position | Built into the chest unit | Whether events happen mostly on your back |
Some devices add heart rate and a snore microphone. Together these signals let a sleep physician score every event, distinguish obstructive from central pauses, and calculate your AHI.
How the night goes, step by step
You collect the device in the evening and return it the next morning. The whole process is designed to feel less like a hospital visit and more like borrowing a Bluetooth speaker.
Setup
A 15-minute appointment in clinic, or a video walkthrough if you live further out. We fit the chest belt, show you the cannula, and pair the finger sensor.
Take it home
Eat dinner as normal. Skip the post-dinner whisky and any sedatives. Coffee after midday is also out.
Bedtime
Switch the device on at your usual sleep time. Sleep on the side or back you normally would.
If a sensor slips
The chest belt can ride up. The finger sensor can come off. Reattach and go back to sleep. The device keeps recording.
Morning return
Drop the unit back at Basheer Bagh or Jubilee Hills. Data is downloaded the same day.
What if I do not sleep well that night?
This is the most common worry, and the answer reassures most patients. We need around six hours of recording. People generally sleep worse than usual on test night and the study still scores. If total recording time falls below the threshold, we repeat the night at no additional device cost.
What your report means: the AHI table
Your AHI (apnea-hypopnea index: pauses in breathing per hour of sleep) is the most important number on the report. The number decides the first-line approach.
| AHI | Severity | Typical first-line approach |
|---|---|---|
| Under 5 | Normal | No sleep apnea treatment; review symptoms |
| 5 to 14 | Mild OSA | Lifestyle changes, positional therapy, sometimes an oral appliance |
| 15 to 29 | Moderate OSA | CPAP therapy usually first-line |
| 30 and above | Severe OSA | CPAP therapy plus a cardiovascular review |
The AHI is one number on a longer report. Oxygen nadir, time spent below 90% saturation, and supine-only events all change the plan. A patient with an AHI of 12 who desaturates to 78% on their back is not the same as a patient with an AHI of 12 who never drops below 91%. We treat the picture, not the headline number. For a fuller view of options across severities, see our page on sleep apnea treatment.
Who should have a home test, and who should not
Home testing is right for most suspected OSA, and wrong for some patients.
Indications that fit home testing
- Loud habitual snoring
- Witnessed pauses in breathing
- Daytime sleepiness or unrefreshing sleep
- Hypertension, especially if poorly controlled
When we recommend an in-lab study instead
- Significant heart failure or known severe lung disease
- Suspected central sleep apnea
- Severe insomnia, where total sleep is unpredictable
- Neuromuscular disease affecting respiration
- Suspected parasomnias or periodic limb movement disorder
We will tell you which test fits your case at the first consultation. If a home test misses something we suspect clinically, we escalate to polysomnography.
How Respire reads your report
Your report is read by a pulmonologist and a sleep physician together. It is not auto-generated by software.
In our clinic, we read every home sleep study report alongside the patient's history before recommending a treatment path. Dr. Pradyut Waghray brings 35+ years of pulmonary and sleep medicine experience. Dr. Kunal Waghray, our interventional pulmonologist (1,000+ bronchoscopies), reviews the airway component. Where ENT findings change the plan, Dr. Jyotika Waghray joins the discussion.
The output is a treatment plan you can act on, not a PDF you have to interpret. Follow-up consultation is included with every home sleep study booking.
Cost and timeline in Hyderabad
Most patients have results within 48 to 72 hours of returning the device.
A home sleep study booking at Respire includes the device for one night, the setup appointment, the scored report, and the follow-up consultation in which we explain the findings and discuss treatment. Contact the clinic for current pricing.
If your case needs in-lab polysomnography, we explain why before you book and provide the referral pathway.
Frequently Asked Questions
How much does a sleep study cost in Hyderabad?
A home sleep study booking at Respire includes the device for one night, the setup appointment, the scored report, and the follow-up consultation. We confirm the figure before you book. Contact the clinic for current pricing.
Can a sleep study be done at home in Hyderabad?
Yes. Respire offers home sleep studies across Hyderabad, with device collection at our Basheer Bagh and Jubilee Hills clinics. For patients further out, we run a video setup and courier the device.
How many hours is a sleep study?
The device records overnight. We need a minimum of around six hours of usable signal to score the study reliably. Most patients record between seven and nine hours.
What should I avoid before a sleep study?
Skip alcohol on the test evening, avoid caffeine after midday, do not take new sedatives, and keep daytime naps short. Stay on your usual prescribed medication unless your doctor has advised otherwise.
What does a sleep study diagnose?
A home sleep study primarily diagnoses obstructive sleep apnea. It also flags significant oxygen desaturation and patterns suggestive of central sleep apnea, which then prompt an in-lab polysomnography for confirmation.
Is a home sleep test accurate?
For suspected moderate-to-severe obstructive sleep apnea in adults without significant heart or lung disease, home testing is validated and recommended by the American Academy of Sleep Medicine clinical practice guideline (Kapur et al., 2017). Outside that group, an in-lab study is more reliable.
How accurate is a home sleep test vs lab?
For the right patient (suspected moderate-to-severe OSA, no significant cardiopulmonary disease), agreement with in-lab testing is high. For complex cases, the lab study scores brainwaves and sleep stages, which a home test cannot.
