Temporal temperature measurement offers a convenient, non-invasive way to assess body heat, popular for all age groups, including infants and children. This method utilizes a specialized thermometer that relies on infrared technology to detect thermal energy from the temporal artery. The temporal artery, located close to the skin surface on the forehead, provides continuous blood flow that reflects the body’s core temperature. Its quick, comfortable application makes it popular for home use.
Steps for Measuring Temporal Temperature
For an accurate temporal temperature reading, ensure the thermometer is clean and ready. Turn on the device and allow it to self-calibrate. Position the probe flat against the center of the forehead, ensuring full skin contact. While holding down the scan button, gently slide the thermometer in a straight line across the forehead towards the hairline, near the temple.
Some models recommend continuing the scan by lifting the thermometer and touching the soft depression behind the earlobe to capture the most accurate temperature. Once the scan is complete, release the button, remove the thermometer, and read the displayed temperature. After each use, clean the thermometer’s sensor and body with an alcohol-based wipe or rubbing alcohol (at least 60% concentration) to prevent germ spread.
Interpreting Your Temperature Reading
Interpreting your temporal temperature involves knowing typical ranges and fever thresholds. A normal temporal temperature for adults is 97.6 to 98.1 degrees Fahrenheit (36.4 to 36.7 degrees Celsius). For children, a normal temporal temperature is 95.9 to 99.5 degrees Fahrenheit. Temporal readings can be slightly lower than oral or rectal measurements.
A temporal temperature of 100.4 degrees Fahrenheit (38 degrees Celsius) or higher indicates a fever. Slight variations in individual body temperature are normal and can be influenced by factors such as activity level or time of day. A single reading provides a snapshot, and observing trends over time can offer a more complete picture of body temperature.
Tips for Accurate Temporal Readings
Several factors influence temporal temperature accuracy, requiring attention to technique and environment. Take the temperature in a room free from drafts, direct sunlight, or extreme temperatures, as these affect skin temperature. Allow the thermometer to acclimate to room temperature if it has been stored in a significantly different environment.
Patient-specific factors also play a role in obtaining a reliable reading. Avoid taking a temperature immediately after strenuous physical activity, crying, eating, or showering, as these can temporarily alter skin temperature. Ensure the forehead is dry and clear of sweat, hair, or cosmetics, which can interfere with the infrared sensor. Regular cleaning and proper handling maintain the thermometer’s functionality and accuracy.
When to Seek Medical Advice
Knowing when to seek medical advice for a fever is important. Contact a healthcare provider if an infant younger than 3 months old has a temporal temperature of 100.4 degrees Fahrenheit (38 degrees Celsius) or higher. For children 3 months or older, medical attention may be warranted if the temperature exceeds 102.2 degrees Fahrenheit (39 degrees Celsius), or if a fever of 100.4 degrees Fahrenheit or higher persists for more than 24 hours in a child under 2 years, or more than 72 hours in a child over 2 years.
Beyond specific temperature thresholds, certain accompanying symptoms should prompt a call to a doctor. These include signs of dehydration, such as reduced urination or lack of tears, or if the individual appears unusually drowsy, very fussy, has a stiff neck, severe headache, difficulty breathing, or a new rash. Always trust your instincts; if concerned about a fever, consult a healthcare professional.
