OSAs

Osas may refer to several concepts in different languages and fields. In Spanish, osa means a female bear, and the plural form osas is used to refer to multiple female bears in wildlife writing and reports.

In medicine, OSAS stands for obstructive sleep apnea syndrome, a sleep-disordered breathing condition. It is characterized by recurrent episodes of partial or complete airway obstruction during sleep, leading to snoring, nocturnal awakenings, and daytime sleepiness. Risk factors include obesity, male sex, older age, craniofacial abnormalities, and smoking. Diagnosis is typically via overnight polysomnography or home sleep apnea testing. Treatments include weight management, continuous positive airway pressure (CPAP), oral appliances, positional therapy, and, in some cases, surgical options depending on anatomy.

Other uses of the acronym OSAS may appear in various institutions or contexts, but these meanings are less standardized and depend on specific organizational naming. When encountered, the intended meaning is usually clarified by the surrounding context.
