Watchapne -

This is the most critical metric for Watchapne. Most high-end wearables use red and infrared LEDs to estimate oxygen saturation. A normal reading is 95-100%. When a person with apnea stops breathing, their oxygen may drop to 85% or even 70%. Your watch logs these "desaturation events."

Myth 1: "If my watch says 100% oxygen, I don't have apnea." False. Mild apnea might cause hypopnea (shallow breathing) without massive oxygen drops. Look for heart rate spikes and restlessness instead. watchapne

Myth 2: "The watch is just as good as a sleep lab." False. A sleep lab measures brain waves (EEG), leg movements, eye movement, and airflow. A watch measures a proxy (oxygen). It is a screening tool, not a diagnostic gold standard. This is the most critical metric for Watchapne

Myth 3: "Only old, overweight men get apnea." False. While risk factors exist, thin women, children, and athletes can have anatomical apnea (large tonsils, recessed jaw, or narrow airway). When a person with apnea stops breathing, their

Wear your watch snugly—one finger above the wrist bone. Loose watches cause false "dips." Also, buy a $20 fingertip pulse oximeter from the pharmacy. Wear it for one night and compare the data. If both devices show drops, it is likely real.
