Abstract

The invention discloses a comparison algorithm for continuous body temperature monitoring over the same period. By using the body temperature Holter for continuous body temperature measurement, a measured value is selected every 10s, and a total of 1500 values are selected from 2:00 to 6:30 in the morning, and the data during this period is disassembled. Divide it into a section every 10 minutes, calculate the average value of each section, and then select the lowest average value as the basal body temperature value on the first day; the calculation of the basal body temperature value on the second day and later is through the same period between the target day and the first day (2:00-6:30) The difference operation of the data, that is, each value in the time period of the target day is subtracted from the value at the same time point on the first day, the difference is taken, and then the average value is taken, plus the value of the second day The basal body temperature value of a day is the basal body temperature value of the target day. The invention accurately calculates the basal body temperature, reduces errors and has simple algorithm.

Description

A Synchronous Comparison Algorithm for Continuous Body Temperature Monitoring

technical field

The invention relates to a body temperature detection method, in particular to a continuous body temperature monitoring period comparison algorithm.

Background technique

At present, the basal body temperature of the human body is usually measured with a medical thermometer after waking up in the morning and before any activity. Basal body temperature has a large error.

The body temperature of the human body is relatively constant. The body temperature of normal people fluctuates slightly within 24 hours. Generally, the difference does not exceed 1°C. The body temperature is slightly lower in the morning and slightly higher in the afternoon, and the body temperature of women is slightly higher before menstruation and during pregnancy. The basal body temperature is the body temperature measured when the person is very quiet and not affected by muscle activity, mental tension, physical objects and ambient temperature, and is usually measured before getting up in the morning. The basal body temperature of women changes with the menstrual cycle. The body temperature is low in the follicular phase, the lowest on the ovulation day, and rises by 0.3-0.6°C after ovulation. Accurate measurement of women's basal body temperature, especially the relative change of basal body temperature, has great influence on infertility. , The diagnosis and treatment of habitual abortion have extremely important clinical significance.

Body temperature Holter is a monitoring system that can realize real-time, continuous and dynamic monitoring of human body temperature and graded risk warning.
