A temple touch thermometer offers a rapid, non-invasive method for measuring body temperature, providing a comfortable alternative to traditional oral or rectal devices. This technology works by sensing the heat flow from the temporal artery, a blood vessel located close to the skin’s surface in the forehead area. Because the temporal artery is a branch of the carotid artery, it provides an accurate representation of the body’s core temperature. This convenience makes it a popular choice for taking temperatures, especially when a quick reading is necessary. Understanding the correct procedure ensures the reading is accurate and reliable.
Preparing the Thermometer for Use
Before taking a measurement, some small steps prepare the device and the subject for an accurate reading. The sensor tip must be cleaned using a cotton swab or cloth moistened with 70% isopropyl alcohol, which cleans and disinfects the probe. After cleaning, it is important to wait at least two minutes before use, allowing the thermometer to adjust back to room temperature. Users should also confirm the thermometer is set to the desired scale, either Fahrenheit (\(^\circ\text{F}\)) or Celsius (\(^\circ\text{C}\)), which can typically be switched by holding the power button while the unit is off.
Ensure the person has been in a stable room temperature environment for a few minutes prior to the measurement. External factors like being outside, exercising, or drinking hot or cold beverages can skew the temperature reading. The forehead area must be clean and dry, so any perspiration should be wiped away before applying the thermometer. Move any hair aside from the temple area so the probe makes direct contact with the bare skin.
Proper Technique for Accurate Reading
The correct physical placement is the most important step for obtaining a precise reading. The sensor should be placed in the center of the temple area, situated between the end of the eyebrow and the hairline, targeting the temporal artery directly beneath the skin. Once positioned, gently press and hold the probe against the temple to maintain good contact throughout the measurement.
The measurement process begins automatically once the thermometer is powered on and placed correctly, or by pressing the multi-function button. The device measures the heat flow from the blood vessels and converts it into a body temperature reading in approximately six to eight seconds. Both the thermometer and the subject must remain still while the measurement is in progress to prevent errors.
A running circle or hourglass icon often indicates the measurement is actively being taken; the process is complete when an audible tone sounds and the final temperature reading locks on the display. Common errors to avoid include moving the probe too quickly, failing to maintain continuous contact, or placing the thermometer over hair or sweat. These errors can lead to an inaccurate or artificially low result.
Understanding Temperature Results and Device Care
The temperature reading from the temporal artery is considered equivalent to an oral temperature, though some models may read about \(0.5^\circ\text{F}\) to \(1^\circ\text{F}\) lower. For adults and children, a reading of \(100.4^\circ\text{F}\) (\(38^\circ\text{C}\)) or higher is considered a fever. This threshold helps determine when medical attention may be necessary, but the patient’s overall appearance and behavior are also important factors.
Proper device maintenance ensures the thermometer continues to provide accurate measurements over time. After each use, the sensor tip should be wiped down. Never submerge the thermometer in water or any other liquid, as the unit is not waterproof.
When the thermometer is not in use, it should be stored in a clean, dry location away from direct sunlight, extreme heat, or excessive dust. Removing the batteries is recommended if the device will not be used for a long period, which helps protect the unit from potential battery leakage.
