Introduction: This guideline establishes clinical practice recommendations for the diagnosis of obstructive sleep apnea (OSA) in adults and is intended for use in conjunction with other American Academy of Sleep Medicine (AASM) guidelines on the evaluation and treatment of sleep-disordered breathing in adults. Methods: The AASM commissioned a task force of experts in sleep medicine. A systematic review was conducted to identify studies, and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) process was used to assess the evidence. The task force developed recommendations and assigned strengths based on the quality of evidence, the balance of benefits and harms, patient values and preferences, and resource use. In addition, the task force adopted foundational recommendations from prior guidelines as "good practice statements", that establish the basis for appropriate and effective diagnosis of OSA. The AASM Board of Directors approved the final recommendations. Recommendations:The following recommendations are intended as a guide for clinicians diagnosing OSA in adults. Under GRADE, a STRONG recommendation is one that clinicians should follow under most circumstances. A WEAK recommendation reflects a lower degree of certainty regarding the outcome and appropriateness of the patient-care strategy for all patients. The ultimate judgment regarding propriety of any specific care must be made by the clinician in light of the individual circumstances presented by the patient, available diagnostic tools, accessible treatment options, and resources. Good Practice Statements:Diagnostic testing for OSA should be performed in conjunction with a comprehensive sleep evaluation and adequate follow-up. Polysomnography is the standard diagnostic test for the diagnosis of OSA in adult patients in whom there is a concern for OSA based on a comprehensive sleep evaluation. Recommendations:1. We recommend that clinical tools, questionnaires and prediction algorithms not be used to diagnose OSA in adults, in the absence of polysomnography or home sleep apnea testing. (STRONG) 2. We recommend that polysomnography, or home sleep apnea testing with a technically adequate device, be used for the diagnosis of OSA in uncomplicated adult patients presenting with signs and symptoms that indicate an increased risk of moderate to severe OSA. (STRONG) 3. We recommend that if a single home sleep apnea test is negative, inconclusive, or technically inadequate, polysomnography be performed for the diagnosis of OSA. (STRONG) 4. We recommend that polysomnography, rather than home sleep apnea testing, be used for the diagnosis of OSA in patients with significant cardiorespiratory disease, potential respiratory muscle weakness due to neuromuscular condition, awake hypoventilation or suspicion of sleep related hypoventilation, chronic opioid medication use, history of stroke or severe insomnia. (STRONG) 5. We suggest that, if clinically appropriate, a split-night diagnostic protocol, rather than a full-night diagnostic protoc...

“…We asked the participants to use a single-channel airflow monitor (Somnie; NGK Spark Plug Co. Ltd, Nagoya, Japan) with a portable monitor attached below the nose during one night 17 of sleep at home and to fill in the self-administered questionnaire on the same day. The Somnie uses a polyvinylidene fluoride film as a thermal sensor to detect airflow, stores the airflow signal as digital data at a sampling frequency of 10 Hz and can record data for 24 h. The airflow sensor is designed to detect both nasal and oral breathing.…”

“…The strength of this method lies in strong agreement between the automated and manual analyses of airflow signal, which has been confirmed in a previous study. 17 The criterion for SDB was defined by the RDI level as 10 and 20 events per hour, because these RDI cutoffs were found to represent AHIs of X15 and X30, respectively, as determined by full polysomnography (PSG); the corresponding sensitivities were 0.91 and 0.89, and specificities 0.82 and 0.96. 17 We eventually used a cutoff for RDI of 10 (corresponding to AHI of 15) for the analysis, because the number of RDI X20 (corresponding to AHI of 30) in weight less categories is too small (n ¼ 20).…”

Background: Limited evidence for association of weight gain with sleep-disordered breathing (SDB) has been produced for Asian populations whose body mass index (BMI) levels are lower than in western countries. Objective: The aim of this study was to examine weight change since 20 years of age and risk of SDB among Japanese. Design: Retrospective cohort study. Subjects: This study includes a large sample of 5320 male Japanese truck drivers aged 30-69 years. Measurements: The respiratory disturbance index (RDI) was selected as an indicator of SDB, and it was estimated with a onenight sleep test using an airflow monitor, and the Epworth Sleepiness Scale (ESS) was used to estimate excessive daytime sleepiness. Results: Respiratory disturbance and sleepiness were more prevalent among men with BMI of 25.0-29.9 and X30.0 kg/m 2 than among those with BMI of 18.5-24.9; multivariable odds ratios (ORs) were 1.8(1.5-2.0), Po0.001 and 4.4(3.5-5.5), Po0.001 for RDI X10, and 1.2(0.9-1.4), P ¼ 0.18 and 1.5(1.1-2.1), P ¼ 0.02 for ESS X11, respectively. Compared with men showing BMI changes within ± 1.0, the respective multivariable ORs for those with BMI changes of 3.0-4.9 and X5.0 were 1.4(1.2-1.6), Po0.001 and 2.4(2.0-2.9), Po0.001 for RDI X10, and 1.2(0.9-1.6), P ¼ 0.22 and 2.0(1.5-2.6), Po0.001 for ESS X11. The corresponding ORs for weight gain of X10.0 kg compared with weight change less than ± 5.0 kg were 2.0(1.7-2.4), Po0.001 for RDI X10 and 1.5(1.2-2.0), P ¼ 0.002 for ESS X11. Similar trends were observed for RDI X20. Conclusion: Our results suggest that an increase in BMI of X5 kg/m 2 or weight gain of X10 kg is a risk factor for SDB and excessive daytime sleepiness among Japanese truck drivers.

“…When the present study was conducted, the types of monitoring devices for SAS/SDB screenings were limited, and we determined that pulse oximetry would be suitable in terms of convenience and cost-effectiveness. In recent years, flow sensors (placed in the nose and mouth to monitor airflow during sleep) that objectively determine apnea and hypopnea during sleep have been developed and are reported to be more feasible for screening of SDB than pulse oximetry 26,27) . The ideal SAS/SDB screening test allows for efficient transition to subsequent comprehensive tests and treatment with as little as possible waiting time.…”

Assessment of Screening Tests for SleepApnea Syndrome in the Workplace: Shigemi TANAKA, et al. Tanaka Internal Medicine ClinicObjectives: The Epworth sleepiness scale (ESS) is often used for screening of sleep apnea syndrome (SAS) in the workplace. We conducted pulse oximetry for workers of a large transportation company, who were selected based on their response to a questionnaire that included ESS and breathing pattern during sleep. Methods: Pulse oximetry was performed for 803 of 3,761 male workers. A 3% oxygen desaturation index (ODI) ≥15 was defined to represent sleep disordered breathing (SDB). We evaluated the frequencies of severe snoring and sleep apnea in the past three months reported by the bed partner or a family member. The relationships between 3% ODI ≥15 and various parameters were analyzed. Results: Of the 715 workers with valid recordings, 3% ODI was ≥15 in 108. The prevalence of 3% ODI ≥15 was high among workers with a body mass index (BMI) ≥25 kg/ m 2 , or for whom severe snoring (≥4 days/wk) or sleep apnea (≥2 days/mo) was reported, but did not correlate with ESS scores. Multivariate analysis showed that 3% ODI ≥15 correlated significantly with BMI, and reported severe snoring and sleep apnea, but not ESS scores. The prevalence of 3% ODI ≥15 was high among obese workers. ESS scores did not correlate with 3% ODI ≥15, irrespective of obesity. Conclusions: Our findings suggest that severe snoring, sleep apnea and BMI, but not ESS, are useful screening tools for SAS. (J Occup Health 2010; 52: 99-105)
