A study from Carlsbad, Calif-based Advanced Brain Monitoring (Assessment of a Neck-based Treatment and Monitoring Device for Positional Obstructive Sleep Apnea) showed that 73% of patients with positional OSA (> 2 times as severe when on their back) is essentially equivalent from an AHI of 2 up to an AHI of 60. It is only those with an AHI > 60 that do not have a positional component.
The findings published in the Journal of Clinical Sleep Medicine using ABM’s Night Shift revealed:
• 83% of POSA participants responded to Night Shift therapy with > 50% reduction in AHI; the median AHI reduction was 79%;
• participants had significantly less sleep fragmentation and hypoxemia, and slept more deeply;
• a majority of participants experienced reduced daytime sleepiness and depression symptoms were significantly reduced; and
• across participants, the percent of time snoring above 50 dB was significantly reduced.
Another Advanced Brain Monitoring study published in the March Journal of Clinical Monitoring and Computing demonstrated the capability of the Night Shift to differentiate benign snores from those with likely OSA.
Key findings were:
• positional snoring measured from the neck was high correlated with overall, supine and non-supine AHI; and
• snoring from the back of the neck was more effective in screening for OSA compared to commonly used questionnaires, provided a sensitivity of 0.82 and a specificity of 0.87.
