[Circadian rhythm of skin temperature of children during puberty]
Abstract:
Results of long-term research of becoming circadian rhythm of temperature (CRT) of human skin of shoulder during puberty are presented. For this purpose, 48-hour monitoring T at children, teenagers and mature young men and female from 8 till 22-th years with application of a method "Thermochron iButton" has been led. Age dynamics of mesor, reflecting process of becoming thermoregulation of organism during puberty, has wave character. The first wave with maximum T was observed at children of 10-11 years, second maximum T--at teenagers of 14-15 years. And at persons man's and female dynamics of mesor is synchronous, however, at girls from 8 till 17 years mesor authentically above. At adult people mesoris above at young men. Dynamics of amplitude CRT does not vary till 12-13 years, in 14-15 years at boys the size of amplitude decreases, and at girls increases. In 16-17 years at children amplitude sharply increases with the subsequent significant decrease by the period of a maturity (20-22 years). At boys, amplitude of CRT it is authentic more, than at girls, at adult people this parameter does not differ. At research of a cycle a dream-wakefulness periods in which changes daily thermoregulation are revealed: at boys in the age of 10-11 years, and at girls at 10-11 and in 16-17 years. During these periods T at night is above, than in the afternoon.

Assessing Body Temperature - Axilla
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...

Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...
