Dr. Lokesh Kumar Saini
Associate Professor, Pulmonary Medicine & Sleep Medicine • AIIMS Rishikesh, India
Dr. Lokesh Kumar Saini is one of India's leading academic sleep medicine specialists, combining over eleven years of post-MD clinical experience with a high-volume research and teaching program at one of the country's most prestigious medical institutions. As Associate Professor in the Department of Pulmonary Medicine at the All India Institute of Medical Sciences (AIIMS) in Rishikesh, he leads one of India's most comprehensive sleep medicine programs — overseeing four Level-1 accredited sleep laboratories and a sleep clinic that manages the full spectrum of sleep disorders.
His clinical and research focus centers on obstructive sleep apnea and sleep-related breathing disorders, including their interaction with chronic pulmonary conditions such as COPD and pulmonary hypertension. Dr. Saini has published extensively on the epidemiology and management of sleep-disordered breathing in Indian populations — research that addresses a critical knowledge gap, since most global OSA data comes from Western cohorts and may not accurately reflect the presentation and prevalence patterns seen in South Asian patients.
Beyond the clinic, Dr. Saini serves as Associate Editor of Sleep and Vigilance, the peer-reviewed journal of the Indian Sleep Disorders Association, contributing to the advancement of sleep medicine research and clinical standards across the subcontinent. His involvement in training the next generation of Indian sleep medicine physicians through the AIIMS program reflects a commitment not just to clinical care, but to building the institutional infrastructure that India's sleep health requires at scale.
Dr. Saini's pulmonology background brings a perspective often missing from sleep medicine discussions: the respiratory physiology of obstructive events, the mechanics of oxygen desaturation, and the long-term cardiopulmonary consequences of untreated snoring and sleep apnea. His work reinforces the understanding that snoring is not a benign nuisance but a respiratory condition warranting clinical attention.

PROFESSIONAL ENDORSEMENT
"From a pulmonology standpoint, every episode of partial or complete airway obstruction during sleep represents a respiratory event with measurable physiological consequences. Conservative interventions that effectively maintain airway patency — particularly dual-mechanism devices that address both jaw position and tongue displacement — align with what the respiratory evidence recommends as first-line management for primary snoring and mild-to-moderate OSA."

Areas of Expertise
Comprehensive diagnosis and management of OSA, from Level-1 polysomnography through oral appliance and CPAP therapy selection.
Oxygen desaturation, hypoxemia during sleep, and the cardiopulmonary consequences of untreated snoring and sleep apnea.
Research on the overlap syndrome of COPD and OSA, and how pulmonary disease interacts with sleep-disordered breathing.
Associate Editor of Sleep and Vigilance; training the next generation of Indian sleep medicine specialists at AIIMS Rishikesh.
Clinical Perspective from Dr. Saini
"In the sleep laboratory, we measure the consequences of airway obstruction with precision — oxygen saturation curves, arousal indices, respiratory effort, and cardiac responses. What these measurements reveal is that snoring exists on a continuum with obstructive sleep apnea: the physiology is the same, the severity varies. Patients who present as 'just snorers' often show oxygen desaturation events that would not have been expected from the clinical history alone. This is why I recommend that anyone with habitual snoring receive proper evaluation, and why conservative interventions that maintain airway patency — before the condition progresses to diagnosable OSA — are so important. A dual-mechanism device that repositions both the jaw and the tongue addresses the two most common anatomical contributors to obstruction. Getting patients into treatment early, with devices they will actually use, is the most important variable in long-term outcomes."
