- Insert the probe into the ear canal.
- Press the button to take the temperature.
- Remove the thermometer and read the display.
- Discard the probe cover.
Interpreting Temperature Readings
Normal body temperature is generally considered to be 98.6°F (37°C), but this can vary slightly from person to person.
- Fever: A temperature of 100.4°F (38°C) or higher is generally considered a fever. The definition of “fever” varies by age and the method used for measurement.
- Hypothermia: A temperature below 95°F (35°C) indicates hypothermia and requires immediate medical attention.
Always consider the thermometer type and location when interpreting the reading. Consult a healthcare professional if you have concerns about your temperature or symptoms.
Common Mistakes and How to Avoid Them
- Using a dirty thermometer: Always clean the thermometer before and after each use.
- Taking an oral temperature after eating or drinking: Wait at least 15 minutes.
- Incorrect probe placement: Ensure the probe is positioned correctly for the chosen method.
- Using the wrong thermometer for the age group: Follow manufacturer guidelines.
- Not accounting for the measurement site: Remember that armpit temperatures are typically lower than oral temperatures.
- Ignoring thermometer instructions: Always read and follow the instructions provided with your specific thermometer model.
