Study Notes

Temperature Measurement

A thermometer is the device used for body temperature measurement.

Oral Method of Body Temperature Measurement

The thermometer should be applied under the tongue, with the mouth closed, and remaining still for about 30 seconds to 1 minute to ensure accurate results.

Routes for Body Temperature Measurement

The oral, axillary, tympanic, and rectal routes are used for body temperature measurement.
The ophthalmic route is NOT used for body temperature measurement.

Contraindications for Oral Method

An absolute contraindication for using the oral method of body temperature measurement is when the patient has a mouth infection or has just consumed hot or cold beverages.

Types of Thermometers

Infrared thermometers use infra-red technology for body temperature measurement.

Body Temperature Regulation

In women, the body temperature increases during the 2nd half of their menstrual cycle due to the increase in progesterone levels.
Diurnal variation (Circadian rhythm) is related to the natural fluctuations in body temperature that occur over a 24-hour period.

Best Medical Thermometer

According to the text, there is no specific mention of the best medical thermometer.

Digital Thermometers

The main advantage of digital thermometers is their fast and accurate measurement.

Standard Route for Body Temperature Measurement

The oral route is considered the standard for measuring body temperature.

Mechanism of Fever

Fever occurs when the hypothalamus, the body's thermostat, is reset to a higher temperature, causing the body to heat up.

Small Intestinal Motility

The apparatus used for recording small intestinal motility is a kymograph.
The curve recorded by a kymograph measures the rhythmic type of small intestinal motility.

Hypothermia and Hyperthermia

Hypothermia occurs when the body temperature drops below 35°C (95°F) due to excessive heat loss or inadequate heat production.
Hyperthermia occurs when the body temperature rises above 40°C (104°F) due to excessive heat production or inadequate heat loss.

Digital and Infrared Devices

The difference between digital and infrared devices is their technology and method of measurement, with digital devices using electronic sensors and infrared devices using infra-red technology.
