A study suggests that positional oximetry is a clinically viable alternative to an auto-scored home sleep apnea test in the characterization of positional obstructive sleep apnea.

In-lab polysomnography (PSG) continues to be the gold standard in diagnosing positional obstructive sleep apnea (POSA), but these studies, especially split-nights, can still result in positional components of sleep apnea being overlooked. Additionally, patients are increasingly doing sleep studies in their own homes. What if there was a simpler way to identify POSA? A team of researchers recently validated the use of oxygen desaturation index (ODI) to recognize positional sleep apnea. Their findings are published in Nature and Science of Sleep.
The use of oximetry is commonly used to screen for obstructive sleep apnea pre-surgically, in epidemiological studies, by dentists to titrate oral appliances, and internationally by general practitioners, says study first author Dan Levendowski, president and co-founder of Advanced Brain Monitoring, which markets Night Shift POSA therapy.
“We believed that each of these applications would benefit
from having positional information. For example, if a patient was identified…
