Electronic device for screening risk degree of obstructive sleep apnea, and operation method therefor

An electronic device comprising:

• a housing;
• a display viewable through a first portion of the housing;
• a photoplethysmogram (PPG) sensor exposed through a second portion of the housing;
• and
• a memory disposed within the housing, and
• a processor disposed within the housing and operatively connected with the memory, the display and the PPG sensor,
• wherein the memory stores instructions that, when executed, cause the processor to:
• receive, from the PPG sensor, first data including a heart rate (HR) data of a user measured during a first period;
• determine a parameter associated with a rate-of-change pattern included in the HR data, based on at least a portion of the first data;
• determine whether at least a portion of the determined parameter is indicative of obstructive sleep apnea (OSA);
• and
• provide information associated with the determination whether the at least the portion of the determined parameter is indicative of OSA through the display.

A method in an electronic device is disclosed, including:

• receiving, for a user, first data from a photoplethysmogram (PPG) sensor, the first data including a pulse signal measured during a first period, and associated with a heartbeat and respiration of the user;
• determining a first parameter associated with a high-frequency component of the pulse signal, and a second parameter associated with a low-frequency component of the pulse signal, based on at least a portion of the first data;
• determining fluctuation ranges for the high-frequency component and the low-frequency component;
• determining whether at least the determined fluctuation ranges are indicative of obstructive sleep apnea (OSA);
• and
• displaying information associated with the determination of whether the at least the determined fluctuation ranges are indicative of OSA through the display.
