Severe Obstructive Sleep Apnea in a Working Professional: Diagnosed with a Sleep Study and Treated with CPAP
Patient Profile
| Age | 44 years |
| Gender | Male |
| City | Noida |
| Occupation | IT professional with long working hours |
| Presenting complaint | Daytime fatigue, morning headaches, and loud snoring for about eight months |
| Key finding | Elevated blood pressure on repeated readings |
| Diagnosis | Severe obstructive sleep apnea (OSA), confirmed on overnight polysomnography |
| Treatment | CPAP therapy with lifestyle guidance |
| Outcome | Daytime sleepiness resolved, headaches settled, and blood pressure improved at three months. |
The Problem
The patient was a 44-year-old software professional who had felt tired through the day for around eight months. He woke with a dull headache most mornings, found it hard to stay focused in afternoon meetings, and had begun to doze off while driving home. His wife reported loud snoring and episodes where his breathing stopped during sleep.
He had attributed the tiredness to work pressure, managing it with extra coffee and weekend sleep. When two routine check-ups found his blood pressure raised, he was referred to a Pulmonologist in Noida to investigate an underlying cause.
Untreated sleep apnea is a recognised cause of daytime sleepiness, morning headaches, and high blood pressure. It also raises the risk of accidents from drowsiness, and over time it strains the heart. Because the symptoms overlap with stress, anaemia, thyroid disease, and depression, it is often missed, and many patients live with it for years.
CONSULTATION & TREATMENT PLAN
What Was Assessed
- Detailed sleep history covering snoring, witnessed breathing pauses, sleep schedule, caffeine use, and daytime sleepiness.
- Epworth Sleepiness Scale score of 14 (above 10 suggests excessive daytime sleepiness).
- Physical examination: BMI 31, neck circumference 42 cm, crowded upper airway, and blood pressure of 150/96 mmHg.
- Blood tests including thyroid function, haemoglobin, and blood sugar, to rule out other causes of fatigue.
- Assessment of driving risk and work demands.
Overnight in-lab polysomnography (sleep study) to confirm and grade the condition.
Why This Approach Was Chosen
Dr. Manu Madan advised a full overnight polysomnography rather than treating the symptoms alone, for clear reasons:
-
-
- Objective diagnosis: the sleep study measures breathing pauses, oxygen levels, heart rhythm, and sleep stages together, which a clinical impression cannot do.
- Severity grading: the result decides whether the patient needs CPAP, an oral appliance, or lifestyle measures alone.
- Right treatment for the grade: CPAP is the first-line treatment for moderate to severe OSA and works by keeping the airway open with gentle air pressure through the night.
- Non-invasive and reversible: no surgery or medication is needed, and the pressure can be adjusted as weight and symptoms change.
-
Procedure Details
The patient underwent a full-night attended sleep study, followed by CPAP initiation. The process is the same one followed for sleep apnea treatment in Noida in patients with suspected moderate to severe OSA.
Step by Step
- Arrival at the sleep laboratory in the evening, with a short briefing on what to expect.
- Sensors attached for brain waves, eye movement, airflow, chest and abdominal effort, heart rhythm, oxygen saturation, and leg movement.
- Overnight recording during natural sleep, monitored by a sleep technologist.
- Study scored and reported by the sleep physician the next day.
- Severe OSA confirmed, and CPAP therapy advised.
- Mask fitting and trial for comfort, with training on use, humidifier settings, and cleaning.
CPAP prescribed with an auto-adjusting pressure range, and data recorded by the device for review.
Procedure Facts
| Investigation | Overnight attended polysomnography |
| Apnea-hypopnea index (AHI) | 38 events per hour (severe: 30 or above) |
| Lowest oxygen saturation | 78% |
| Treatment started | CPAP therapy with nasal mask and heated humidifier |
| Anaesthesia | Not required |
| Complications | None reported |
| Hospital stay | Overnight study; discharged the next morning |
Post-Procedure Results
At the three-month review with Dr. Manu Madan, device data showed the patient was using CPAP on most nights for more than six hours, with residual AHI on treatment falling to 3 events per hour. The patient had adapted within the first two weeks after a mask change improved the fit. His wife reported that the snoring and breathing pauses had stopped.
By the second month, the afternoon sleepiness had gone and the morning headaches no longer occurred. He resumed driving without drowsiness. His blood pressure improved on repeated readings, and weight-loss and exercise advice was reinforced at each visit.

PATIENT FEEDBACK
Recorded during clinical follow-up:
“I thought I was just overworked. After the sleep study, I understood why I was exhausted even after a full night in bed. The mask felt strange for the first week, but within a month I was waking up clear-headed for the first time in years. The headaches are gone, and my blood pressure reading has come down.”
Post-Treatment Care and Recovery
Instructions Given to the Patient
- Use CPAP every night and for naps, for the whole sleep period, not only part of it.
- Clean the mask, tubing, and humidifier chamber regularly as taught.
- Avoid alcohol and sedatives close to bedtime, as they relax the airway further.
- Aim for gradual weight loss and regular exercise, which can lower the pressure needed.
- Sleep on the side rather than the back where possible.
- Avoid driving when drowsy, and report any return of sleepiness or snoring.
- Attend scheduled reviews so device data can be checked and pressure adjusted.
Recovery and Adaptation Timeline
| Timeframe | What the Patient Can Expect |
| Night 1 to 7 | Getting used to the mask and air pressure. Minor dryness or mask leaks can be fixed with humidifier and fit changes. |
| Week 2 to 4 | Sleep becomes more settled. Morning headaches and daytime sleepiness begin to ease. |
| Month 2 | Energy and concentration improve. Device data reviewed. |
| Month 3 | Review with CPAP data, symptom score, and blood pressure check. |
| Ongoing | Annual review, with pressure and mask adjusted as needed. |
