Overview
A sleep study test is a specialised diagnostic evaluation used to monitor body functions during sleep and identify underlying sleep disorders. Also known as a polysomnogram test, it records brain activity, breathing patterns, oxygen levels, heart rate, and muscle movements throughout the night.
At Sarvodaya, a leading chest hospital in Delhi NCR, sleep studies are conducted in a controlled, comfortable setting under expert supervision. Guided by the best pulmonologist in Delhi NCR and supported by advanced monitoring systems, this test helps diagnose sleep-related breathing disorders and other complex sleep conditions accurately.
Why a Sleep Study Test Is Required?
A sleep study test is recommended when patients experience persistent snoring, daytime fatigue, breathing pauses during sleep, insomnia, or unexplained sleep disturbances. These symptoms may indicate obstructive sleep apnea, central sleep apnea, or other neurological and respiratory disorders.
Under the evaluation of the best pulmonologist in Faridabad, a sleep study helps detect conditions that may increase the risk of heart disease, stroke, hypertension, and metabolic disorders. Early diagnosis ensures timely and effective treatment.
Procedure of Sleep Study?
A sleep study, also known as polysomnography, is a non-invasive and painless test conducted to evaluate sleep patterns and identify sleep-related disorders. The test is usually performed overnight in a dedicated sleep laboratory under the supervision of trained technicians.
During the study, small sensors are gently attached to the scalp, chest, limbs, and finger to record key physiological parameters, including brain waves and sleep stages, breathing pattern and airflow, blood oxygen levels, heart rhythm, body movements, and snoring activity. These sensors do not cause discomfort and do not interfere with normal sleep.
The test typically lasts through the night. In selected cases, a home-based sleep study may be advised based on clinical assessment. Patients often worry about not being able to sleep during the test, but even limited or fragmented sleep provides sufficient data for accurate interpretation by sleep specialists.
Technology and Infrastructure
Sleep studies are conducted using advanced digital polysomnography systems with high-resolution monitoring and real-time data analysis. Dedicated sleep labs provide a quiet, comfortable environment that simulates natural sleep conditions.
At Sarvodaya Hospital, the sleep lab is supervised by respiratory experts and technicians working closely with the best pulmonologist in Noida and Delhi NCR to ensure reliable and accurate diagnostic outcomes.
Benefits of a Sleep Study Test
- Accurate diagnosis of sleep apnea and related disorders: Confirms sleep apnea and other sleep disorders through detailed analysis of breathing patterns, oxygen levels, and sleep stages.
- Identification of abnormal sleep stages or disrupted sleep cycles: Detects disturbed sleep architecture, frequent awakenings, and poor sleep quality affecting daily alertness and overall health.
- Assessment of oxygen desaturation and breathing irregularities: Measures drops in blood oxygen levels and abnormal breathing events occurring repeatedly during sleep.
- Guidance for CPAP therapy and other sleep apnea treatments: Helps determine appropriate CPAP settings and guides personalised treatment planning for effective sleep apnea management.
- Prevention of long-term cardiovascular and neurological complications: Early detection reduces the risk of heart disease, stroke, memory problems, and other complications linked to untreated sleep disorders.
Post Treatment and Lifestyle Modifications
- Weight management: Achieving and maintaining a healthy weight helps reduce airway obstruction during sleep, improving breathing patterns and decreasing the severity of sleep apnea symptoms.
- Avoiding alcohol and sedatives before bedtime: Alcohol and sedatives relax throat muscles, worsening airway collapse during sleep and increasing the frequency and severity of breathing interruptions.
- Maintaining a regular sleep schedule: Following a consistent sleep and wake routine supports better sleep quality, stabilises circadian rhythm, and reduces daytime fatigue and sleep disturbances.
- Using CPAP or BiPAP devices as prescribed: Regular use of CPAP or BiPAP maintains airway patency during sleep, reduces apnea episodes, and improves oxygen levels and sleep continuity.
- Regular follow-up with a pulmonologist: Ongoing medical follow-up ensures treatment effectiveness, device adjustments, symptom monitoring, and early identification of complications or therapy-related issues.
