• 1.About the evaluation of obstructive sleep apnea (ICD 10: G47.3):
• 1.1.The drivers of motor vehicles, when they renew, add, or change to categories C, D, and E should be evaluated with regard to Obstructive Sleep Apnea Syndrome (OSAS) according to the following parameters:
• 1.1.1.Objective parameters: systemic arterial hypertension, body mass index, cervical circuference, modified Mallampati classification⁷;
• 1.1.2.Subjective parameters: excessive sleepiness measured by the Epworth Sleepiness Scale⁸;
• 1.2.According to the aforementioned parameters, the following results will be considered indicative of sleep disorders:
• 1.2.1.Systemic arterial hypertension: systolic pressure > 130 mm Hg and diastolic pressure > 85 mm Hg;
• 1.2.2.Body Mass Index (BMI): > 30 kg/m²;
• 1.2.3.Cervical circuference (measured at the cricoid cartilage): male > 45 cm and female > 38 cm;
• 1.2.4.Modified Mallampati classification: class 3 or 4 (Attachment XII);
• 1.2.5.Epworth Sleepiness Scale: ≥ 12.
• 1.3.An applicant who has a score in the Epworth Sleepiness Scale ≥ 12 and/or has ≥ 2 objective indications of sleep disorders might, according to the physician's criteria, be approved temporarily or referred to specific medical evaluation and undergo a polysomnographic exam (PSG).
