It’s hard to pronounce, but photoplethysmography is a key driver in the explosion of wearable health tracking. It uses those ...

Polysomnography is the current gold standard in sleep testing, but a new method has achieved similar performance in sleep stage scoring via an electrocardiography-based deep learning neural ...

CLEVELAND--(BUSINESS WIRE)--General Sleep Corporation announces the latest innovation in home sleep monitoring, the Zmachine® Insight. The Insight system revolutionizes the process by which sleep ...

So, the researchers trained a neural network using a large dataset of 4,000 PSG recordings – a total of 38,311 hours of data – with a wide range of sleep stage ratios from people aged five to 90.

Sleep latency is the amount of time it takes you to go from being fully awake to being asleep. ... (PSG). A PSG is an overnight sleep study that monitors sleep cycles and sleep stages.

Sleep parameters measured in these studies included sleep duration, sleep efficiency, sleep latency, sleep architecture, stage shifts, wake after sleep onset (WASO), sleep continuity, and total ...

Participants sleep overnight in a laboratory while wearing both a sleep tracker and undergoing PSG. Then, scientists compare the data from both methods in 30-second blocks called“epochs”.
