How Do You Use a Thermometer Under Your Arm?

Published in Body Temperature Measurement 2 mins read

Using a thermometer under your arm, also known as the axillary method, is a common way to check body temperature, especially in children. It's a simple process that involves placing the thermometer correctly and waiting for the appropriate time.

Steps for Taking Armpit Temperature

To accurately measure temperature using the armpit method, follow these key steps based on standard guidelines:

  1. Prepare the Armpit Area: Ensure the armpit is dry. Excess moisture can affect the reading.
  2. Position the Thermometer: Place the thermometer in the armpit. Make sure the tip is directly in the center of the armpit.
  3. Secure the Thermometer: Press the arm against the body. This holds the thermometer firmly in place and ensures good contact with the skin, trapping heat in the area.
  4. Wait for the Reading: Wait for 5 minutes before reading or when the device beeps. Different thermometers have different waiting times. Digital thermometers often beep when they have registered a stable temperature.

Key Considerations

  • Type of Thermometer: This method is typically used with digital stick thermometers.
  • Accuracy: Armpit temperatures are generally considered less accurate than oral or rectal temperatures, but they are a safe and non-invasive option.
  • Reading the Temperature: Once the waiting time is complete or the thermometer beeps, carefully remove it and read the displayed temperature.

By following these steps – place the thermometer in the armpit, press the arm against the body, and wait for 5 minutes before reading or when the device beeps – you can effectively use a thermometer to take an armpit temperature.
