Obstructive Sleep Apnea (OSA) is the most common type of sleep apnea and is caused by complete or partial obstructions of the upper airway. It is characterized by repetitive episodes of shallow or paused breathing during sleep, despite the effort to breathe, and is usually associated with reduction in blood oxygen saturation. These episodes of decreased breathing, called "apneas" (literally, "without breath"), typically last 20 to 40 seconds and can occur around 30 to 300 times during sleep.
Individuals with OSA are rarely aware of the difficulty breathing, even upon awakening. It is estimated that Obstructive Sleep Apnea (OSA) affects approximately 13% of the adult population in India and out of this only about 4% visit their doctor with the symptoms, a large proportion of these cases go undiagnosed.
The first step is visiting your doctor, who will ask you a simple series of questions to determine your risk. If your doctor believes that you may be suffering from OSA, they will recommend that you get a sleep study done.
Polysomnographies (Sleep studies) are tests that record body activity during sleep. They are helpful in identification of sleep disorders. Polysomnography is the gold standard to rule out Obstructive Sleep Apnea. Polysomnography records several body functions during sleep, including brain activity, eye movement, blood O2 and CO2 levels, heart rate and rhyhtm, breath rate, snoring and body muscle movement.

PAP (Positive Airway Pressure) is an effective treatment for OSA. PAP therapy prevents upper airway collapse during sleep by providing a gentle flow of air through the upper airway, allowing you to breathe freely.
CPAP Therapy - A Continuous Positive Airway Pressure (CPAP) device is the most commonly used treatment for OSA. CPAP provides a continuous stream of air to keep your upper airway open.
BiPAP Therapy - While CPAP devices are aimed at delivering a constant pressure, Bi-Level Positive Airway Pressure (BiPAP) therapy devices are set to deliver two levels of pressure - a lower pressure when you exhale and a higher pressure when you inhale. These are prescribed for patients who are not compliant with CPAP therapy or have trouble tolerating it.
