None of the studies found significant differences in disease management parameters.…”

“…Still, PSG is the method of choice and has been established as the 'gold standard' to determine SRBD. Unfortunately, the identification of the level of obstruction with this method is not possible, it is labor-intensive and continuous monitoring of the patient during the night is mandatory [4,[11][12][13] . Various diagnostic procedures, including different home-diagnostic systems that can diagnose SRBD, have been compared to PSG.…”

Purpose: To evaluate whether ApneaGraph (AG) and polysomnography (PSG) deliver comparable results in patients with sleep-related breathing disorders. Procedures: A prospective study was performed, which included 14 patients with obstructive sleep apnea syndrome. Apnea-hypopnea index (AHI), hypopnea index (HI), apnea index (AI), obstructive, central and mixed apnea, oxygen saturation (SaO₂), pulse and body position were simultaneously assessed by PSG and AG in each individual. Results: There was a good correlation between measurements of AG and PSG for AHI, pulse, SaO₂, body position and central apnea. However, our study showed differences between PSG and AG for AI (p = 0.002), HI (p = 0.013), mixed apnea (p = 0.003) and obstructive apnea (p = 0.013). AG indicated that 2/14 patients had a pure upper airway obstruction, 6/14 patients had a predominance of lower obstruction and 6/14 patients had a predominance of upper obstruction. Conclusion: AG provides comparable results for AHI, pulse, SaO₂, body position and central apnea when compared to PSG, but not for the rest of the measurements. Using AG, the distribution of sites of obstructive events could be identified in this study in all of the patients.

“…Use of PSG in the home or laboratory setting has substantial costs for data acquisition and the time required for data processing while potentially imposing physical and psychological burdens on the participant. 7 Given these considerations, it is important to ascertain how much and what kind of data must be collected, determine if more than a single night's data collection is required to describe sleep behaviors; and, identify personal characteristics associated with substantially increased within-person variation in sleep behaviors.…”

Study Objective: To quantify sources of night-to-night variability. Methods: This project was conducted in 285 middle-aged African American, Caucasian, and Chinese women from the Study of Women's Health Across the Nation (SWAN) Sleep Study living in Chicago, the Detroit area, Oakland, and Pittsburgh. The study used 3 repeated nights of in-home polysomnography (PSG) measures. Night 1 data included assessment of sleep staging, sleep apnea, and periodic limb movements, while Nights 2 and 3 focused on sleep staging. Results: Mean total sleep time (TST) increased substantially from 365 minutes on Night 1 to 391 minutes and 380 minutes, respectively, on Nights 2 and 3. Mean percent sleep effi ciency (SE%) for the 3 nights were 83%, 85%, and 85%, respectively. Night 1 sleep values were signifi cantly different than Nights 2 and 3 measures except for S2 (%), S1 (min), and Delta (S3+4)%. Nights 2 and 3 differences in variability were negligible. Obesity, past smoking, and fi nancial strain measures were associated with greater Night 1 vs. Night 2 or Night 3 differences. We concluded that there was signifi cant Night 1 vs. Nights 2 and 3 variability and, though relatively modest, it was suffi cient to bias estimates of association. Additionally, personal characteristics including smoking, obesity, and fi nancial strain increased night-to-night variability. Conclusions: This reports adds new information about between and within person sources of variation with in-home PSG and identifi es elements that are essential in the design and planning of future sleep studies of multi-ethnic groups in social and physiological transition states such as the menopause. Keywords S C I E N T I F I C I N V E S T I G A T I O N SP olysomnography (PSG) is widely used in clinical and epidemiological research settings to provide objective sleep measures.1-6 PSG can be conducted using in-home settings or sleep laboratories considering the advantages afforded by variability in the closeness of monitoring, the ability to correct technical problems in a timely manner, and control temperature, noise and other environmental factors to minimize systematic bias. Use of PSG in the home or laboratory setting has substantial costs for data acquisition and the time required for data processing while potentially imposing physical and psychological burdens on the participant.7 Given these considerations, it is important to ascertain how much and what kind of data must be collected, determine if more than a single night's data collection is required to describe sleep behaviors; and, identify personal characteristics associated with substantially increased within-person variation in sleep behaviors.Considering the number of data collection nights that are needed to provide unbiased estimates of sleep characteristics is often made more complex because of the impact of the "fi rst night" effect (FNE), generated from changes in the sleep envi-BRIEF SUMMARY Current Knowledge/Study Rationale: Use of repeated polysomnography (PSG) in the home or laboratory to descr...
