apnea

For neurological conditions like anxiety or apnea, the chemical needs to be absorbed into the bloodstream to have maximum impact.

Pulmonologists estimate that some 80 percent of moderate to severe apnea goes undiagnosed.

After an Australian physician invented CPAP in 1980, Rapoport improved the circuitry and showed it worked for sleep apnea nearly 100% of the time.

SpO2, in particular, will become an increasingly important factor in sleep going forward, as these devices look to track things like sleep apnea.

To make that case, researchers are studying people with disorders like sleep apnea, or those who work night shifts or keep irregular working hours, such as first responders, pilots and flight attendants.

Take, for instance, those with sleep apnea, in which breathing periodically stops and starts throughout the night.

Snoring is a sign of obstructive sleep apnea, when your airway collapses or becomes blocked during sleep.

Sometimes people with sleep apnea wake up during the night gasping for breath.

More troubling were the episodes of central apnea we had been warned about.

And in other research, people with sleep apnea were found to have more difficulties with sexual function.
