A team led by Associate Professor Dominik Linz and Associate Professor Mathias Baumert of the University of Adelaide's Medical School and School of Electrical and Electronic Engineering has published their study in the European Heart Journal which examined patterns of low blood oxygenation during sleep and the relation to heart-related deaths in 2840 men aged in their 70s and early 80s.

"Understanding underlying causes of low oxygen saturation during sleep is important as this may assist in preventing deaths," says Associate Professor Linz.

Study - Time - Blood - Oxygenation - Chance

"The study shows for the first time that poor blood oxygenation during sleep predicts the chance of heart-related death in elderly men. The study also demonstrates that reduced blood oxygenation cannot be attributed to episodic drops in oxygen alone."

A healthy person normally has a 95-100 per cent saturation during the day. Oxygen saturation is slightly lower while a person sleeps due to shallower breathing. Saturation below 90 per...
