Electronic device and method for identifying occurrence of hypotension

1. An electronic device comprising:

a housing;

a user interface;

a photoplethysmogram (PPG) sensor exposed through at least part of the housing;

a motion sensor disposed in the housing;

at least one processor operatively coupled with the user interface, the PPG sensor, and the motion sensor; and

a memory operatively coupled with the at least one processor,

wherein the memory stores instructions which, when executed by the at least one processor, cause the at least one processor to:

obtain a first data from the motion sensor with the PPG sensor disabled,

detect a change of a user's operating state which increases a probability of occurrence of hypotension based on that the first data from the motion sensor indicates a first change of a first selected pattern,

in response to detecting the change of the user's operating state, enable the PPG sensor during a predesignated time period to monitor a blood pressure value based at least in part on second data from the PPG sensor, and

based on the blood pressure value being lower than a first threshold, provide a notification through the user interface, and

wherein the predesignated time period is set based on a type of hypotension to be monitored and information on physical characteristics of the user.

2. The electronic device of claim 1 , wherein the first selected pattern comprises a pattern which changes from a state in which the first data is lower than a second threshold to a state in which the first data is higher than a third threshold.

3. The electronic device of claim 1 , wherein the first selected pattern comprises a pattern which changes from a state in which the first data is higher than a third threshold to a state in which the first data is lower than a second threshold.

4. The electronic device of claim 1 , wherein the instructions further cause the at least one processor to:

before a second change of a second selected pattern occurs, control the PPG sensor to monitor a blood pressure on a first cycle; and

after the second change of the second selected pattern occurs, control the PPG sensor to monitor the blood pressure on a second cycle which is shorter than the first cycle.

5. The electronic device of claim 1 , wherein the user interface comprises at least one of a display, a speaker, or a light emitting diode (LED).

6. The electronic device of claim 1 , wherein the instructions further cause the at least one processor to:

based on the blood pressure value being lower than the first threshold, provide a notification to another electronic device using designated identification information.

7. The electronic device of claim 1 ,

wherein the user's operating state comprises at least one of a stationary state, a sedentary state, or a moving state, and

wherein the instructions further cause the at least one processor to:

when the type of hypotension to be monitored is a first type, detect that the user's operating state is changed from a first state to a second state using the first data, and

when the type of hypotension to be monitored is a second type, detect that the user's operating state is changed from a third state to a fourth state using the first data.

8. An operating method of an electronic device, the operating method comprising:

obtaining a first data from a motion sensor with a PPG sensor disabled;

detecting a change of a user's operating state which increases a probability of occurrence of hypotension based on that the first data from the motion sensor of the electronic device indicates a first change of a first selected pattern,

in response to detecting the change of the user's operating state, enabling a photoplethysmogram (PPG) sensor during a predesignated time period to monitor a blood pressure value based at least in part on a second data from the PPG sensor of the electronic device; and

based on the blood pressure value being lower than a first threshold, providing a notification through a user interface of the electronic device,

wherein the predesignated time period is set based on a type of hypotension to be monitored and information on physical characteristics of the user.

9. The operating method of claim 8 , wherein the first selected pattern comprises a pattern which changes from a state in which the first data is lower than a second threshold to a state in which the first data is higher than a third threshold.

10. The operating method of claim 8 , wherein the first selected pattern comprises a pattern which changes from a state in which the first data is higher than a third threshold to a state in which the first data is lower than a second threshold.

11. The operating method of claim 8 , further comprising:

before a second change of a second selected pattern occurs, monitoring a blood pressure from the PPG sensor on a first cycle; and

after the second change of the second selected pattern occurs, monitoring the blood pressure from the PPG sensor on a second cycle which is shorter than the first cycle.

12. The operating method of claim 8 , further comprising:

based on the blood pressure value being lower than the first threshold, providing a notification to another electronic device using designated identification information.
