Obstructive Sleep Apnea STOP-Bang Score Calculator

The STOP-BANG score makes it possible to detect subjects at risk of Obstructive  sleep apnea. 

- Low risk of Obstructive sleep apnea: Score from 0 to 2.  

- Moderate risk of Obstructive sleep apnea: Score of 3 to 4.

- High risk of Obstructive sleep apnea: Score of 5 to 8, or STOP ≥ 2 and male gender, or STOP ≥ 2 and BMI > 35, or STOP ≥ 2 and neck circumference > 40cm.


Obstructive Sleep Apnea-Hypopnea Syndrome (OSAS, formerly known as OSAS, Obstructive Sleep Apnea Syndrome) is a sleep disorder where the sleeper suffers from pauses in breathing or decreased airflow. These repeated drops or stops in breathing usually only last a few seconds, but they cause a drop in blood oxygenation. The heart therefore works abnormally hard to try to mobilize all the oxygen reserves. These breathing difficulties cause micro-awakenings of a few seconds of which the sleeper is not necessarily aware.

It is considered that there is proven OSAS when the sleeper experiences more than ten breathing pauses (apneas) per hour of sleep (in the United States, the threshold is five apneas per hour). To establish the diagnosis, an apnea is defined as an interruption of breathing for more than ten seconds. Decreases in respiratory flow (hypopneas) are identified by measuring the oxygen saturation of the blood during sleep (during a night spent in a sleep study centre): during a hypopnea, the blood is less saturated with oxygen .


People who suffer from sleep apnea syndrome complain of drowsiness during the day, headaches when getting up, waking up suddenly during the night, night sweats, having to get up frequently at night to urinate , irritability and aggressiveness, even depressive episodes. Sometimes they signal memory and concentration problems, as well as a decrease in sexual desire, or even impotence. It is estimated that this syndrome is present in 1 to 5% of adult men.
