How to Use Underarm Digital Thermometer

Thermometers are usually used to determine the presence of temperature. Since using a thermometer is important for your health, so learn it before measuring temperature.

There are different methods for measuring temperature & this article will help you to know how to use an underarm digital thermometer.

Method

Normal temperature

Armpit

36.5°C - 37.5°C (97.8°F - 99.5°F)

Oral

35.5°C - 37.5°C (95.9°F - 99.5°F)

Ear

35.8°C - 38°C (96.4°F - 100.4°F)

Rectal (Bum)

36.6°C - 38°C (97.9°F - 100.4°F)

How to Use Underarm Digital Thermometer – Measuring underarm temperature (digital thermometer)

Read the instructions for using the thermometer carefully

1. Read the instructions for using the thermometer carefully, because the beeps of different thermometers can mean different things.

  • Axillary temperature is not as accurate as radial or oral measurements, but this method does not involve penetration into the body cavity and is recommended for rapid determination of temperature in a child under 5-years of age.
  • If the armpit measured temperature is 37.0 Degrees centigrade but use another temperature measurement method to determine its exact value.
 Turn on the thermometer and check

2. Turn on the thermometer and check that it falls to zero. Ask the patient to remove the shirt to make sure the tip of the thermometer is directly under the armpit when measuring the temperature.

If the patient is a child, explain to him that he should not move while taking the temperature.

Ask the patient to raise their hand and place

3. Ask the patient to raise their hand and place the tip of the thermometer on the armpit. Then lower the patient’s hand and ask him to hold the thermometer.

  • The patient must hold the thermometer firmly so that it does not move.
  • The metal tip of the thermometer must be pressed against the patient’s skin to obtain accurate readings.

4. The thermometer detects the temperature as soon as the signal is heard (it takes about 4-5 minutes).

  • Make sure that the patient does not move while taking the temperature.
  • If the thermometer slips from the armpit, wait a few minutes and then repeat the temperature measurement process.

5. If the armpit measured temperature is 37.0

  • If the degree is above centigrade, use another temperature measurement method to determine its exact value.
  • Children’s temperature can be measured orally, but babies (up to three months of age) should have their temperature measured rectally.

6. Clean the thermometer & store it for its next use.

For this method, the thermometer is placed in the Underarm for young children/adults whose temperature can’t safely be done orally. This process is not as accurate as oral/rectal but can be used as a first check. You can follow this with oral/rectal reading.

Cleaning Instructions

Cleaning Instructions
  • First, wash the thermometer with the spirit or soap water & wipe with a dry cloth. If it is a digital thermometer, make sure that water does not enter inside.
  • Check the position of the mercury if it is an ordinary thermometer. If it is above 98 degrees, shake it hard & lower the mercury. However, turn it on by pressing the switch, If it’s a digital thermometer.
  • The base of the ordinary thermometer should be placed under the armpit or tongue for 1-2 minutes. Either if you check the thermometer you can see the result. In the case of a digital thermometer, you can see the result clearly.
  • In adults/grown-ups, fever is measured by placing a thermometer under the tongue.
  • After measuring the fever, the thermometer should be washed & wiped.
