Aim:
Obstructive Sleep Apnea Syndrome (OSAS) is an under diagnosed condition with significant consequences on health. The aim of this study is to estimate the prevalence of symptoms and key features of OSAS in a rural population.
Material And Methods:
254 subjects were enrolled. We measured height (H) and weight (W), calculated body mass index (BMI) and determined glycated hemoglobin (HbA1c). Information about age, gender, medical history (diabetes, hypertension) was collected. All the participants filled in the Berlin questionnaire, which has separate questions regarding the symptoms of OSAS.
Results:
Snoring was reported by 44.1% of the subjects, observed apneas by 6.7% and excessive daytime sleepiness by 36.6%. All symptoms were more frequently reported by women. A higher percentage of obese, hypertensive and diabetics reported snoring (p < 0.001). When analyzing gender differences, the significance was maintained, except for diabetic men. Witnessed apneas were more prevalent in hypertensive subjects (p = 0.034), but were significantly associated with hypertension only in (p = 0.003). No correlation was found regarding excessive daytime sleepiness and the risk factors studied.
Conclusions:
Prevalence of OSAS symptoms and risk factors in this rural population was noticeable and efforts for early diagnosis and treatment are recommended.

Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
