Obstructive sleep apnea (osa) is a sleep disorder characterized by repeated episodes of interrupted breathing during sleep. These episodes occur when the airway is partially or completely blocked, making it difficult to breathe. This can lead to a drop in oxygen levels in the blood, which can cause the person to awaken briefly in order to restart breathing. Osa is a common condition that can cause excessive daytime sleepiness, difficulty concentrating, and an increased risk of heart disease, stroke, and other health problems. The most common treatment for osa is the use of a continuous positive airway pressure (cpap) machine, which delivers air pressure to the airway to keep it open during sleep.
