How to take the temperature with a digital thermometer?

 

Fever is a symptom of an illness but not an illness itself. Fever is the body’s way of reacting to help fight the illness. The discomfort and the illness causing the fever is often more of a concern than the high-temperature reading.               

         

1. What type of thermometer should you use?

A digital thermometer is best for taking temperatures by the armpit and mouth. You can get fast and accurate readings with a digital thermometer. A pacifier thermometer cannot provide an accurate temperature. Mercury in mercury thermometers is toxic and the thermometer may break. Besides,  If the temperature of 99.7 *F or higher is detected, the alarm will beep to indicate a fever. Therefore, choosing a safe and environmentally friendly thermometer is a must thing.

 

  

2. 4 methods to take the temperature:  

Under the armpit (axillary method)

In the mouth (oral method)

In the ear (tympanic method)

In the rectum (rectal method)

Before the start, please press the on/off button next to the LCD display. When the screen displays the temperature, a tone will sound. It is in a test mode with the most suitable temperature display. Then place the thermometer in the desired position.

 

Axillary method (under the armpit)  

The armpit method is usually used to check for fever in newborns and young children. Use this method only if your child has a condition that does not allow rectal temperatures or if he cannot use an oral thermometer. Normal temperature varies between 36.5°C and 37.5°C (97.8°F and 99.5°F)

  • Wipe the armpit dry.
  • Place the probe in the armpit
  • Tuck the arm snugly against their body
  • Leave the thermometer in place for about 1 minute, until you hear the “beep”
  • Remove the thermometer and read the temperature

 

Oral method (in the mouth)  

Older children can usually have their temperature taken by mouth. This method can be used for children who are older than 5 years of age and the adult. It is not recommended for children younger than 5 years old, because it is hard for them to hold the thermometer under their tongue long enough. Normal temperature varies between 35.5°C and 37.5°C (95.9°F and 99.5°F)

  • Carefully place the tip of the thermometer under your tongue
  • With the mouth closed, leave the thermometer in place for about 1 minute until you hear the “beep”
  • Remove the thermometer and read the temperature

Note:  

  • Keep lips firmly closed but not to bite the thermometer.
  • Cold / hot drinks or chewing gum can change oral temperature. Wait 15 minutes after eating or drinking before taking a temperature by mouth.
  • Wash your hands with soap and warm water.
  • Use a clean thermometer, one that has been washed in cold water, cleaned with rubbing alcohol, and then rinsed to remove the alcohol.

 

Digital Thermometer

 

Tympanic method (in the ear)    

This method is recommended for children older than 2 years old and the adult. Though quick to use, the ear method can produce temperature readings that are incorrect, even when the directions are followed. Normal temperature varies between 35.8°C and 38°C (96.4°F and 100.4°F).

  • Use a clean probe tip each time, and follow the instructions carefully
  • Gently tug on the ear, pulling it back. This will help straighten the ear canal and make a clear path inside the ear to the eardrum
  • Gently insert the thermometer until the ear canal is fully sealed off
  • Squeeze and hold down the button for 1 second
  • Remove the thermometer and read the temperature

 

 

Rectal method (in the rectum)  

The rectal method is suitable for infants under 3 months and children under 3 years old. Use a rectal thermometer only if you are comfortable doing so and a health care provider has shown you how to do it safely. Normal temperature varies between 36.6°C and 38°C (97.9°F and 100.4°F).

  • Cover the silver tip with petroleum jelly (such as Vaseline)
  • Place your baby on their back with their knees bent
  • Gently insert the thermometer in the rectum, about 2.5 cm (1 inch), holding it in place with your fingers
  • Leave the thermometer in place for about 1 minute until you hear the “beep”
  • Remove the thermometer and read the temperature

Note:

  • After a thermometer has been used to take a rectal temperature, do not use it to take an oral temperature. Be sure to label your thermometer either “oral” or “rectal” to know the difference.
  • Be sure to wash your hands thoroughly with warm soapy water.

 

 

3. How to take an adults temperature?

Take an adult’s temperature by mouth, in the ear or under the armpit. The armpit method is less accurate and is normally only used if the person is extremely drowsy or not clear mentally. Follow the same methods used for taking a child’s temperature.

 

 

4. What is a normal temperature?

Normal human body temperature varies between 98.6 ° F to 100 ° F or 37 ° C to 37.8 ° C. Temperatures vary throughout the day, rising as much as 1 degree in the morning and reaching a maximum during the late afternoon or evening. Mild increases may be caused by exercising, too much clothing or bedding, taking a hot bath or being outside in hot weather. 

When you are sick with an infection, it is normal to have a fever (temperature higher than 38°C or 100.4°F). A fever is part of the normal process of fighting an infection. Usually, it goes away after 3 days. Please call the health care provider right away if you have a fever and the following symptoms: severe headache, stiff neck, swelling of your throat and confusion.

If the screen shows “Lo”, it means that the measured temperature is lower than 90°F, please turn off, wait a minute and take a new temperature via close contact and sufficient rest. As for switching from Fahrenheit to Celsius, please long press the ON/OFF button for 4 seconds to convert.

Here are the normal temperatures of 4 methods:

5. How to care for your thermometer?

Please remove the probe cover after using it. Clean its’ end with a soapy cotton ball or tissue and cool water. Rinse it with cool water. Store it in a safe place out of reach of children. 

 

The following stuff can not be used to prevent from damaging the thermometer:

  • Benzene, thinner, ultrasonic, gasoline or other strong solvents;
  • Do not attempt to disinfect the sensing section (tip) of the thermometer by immersing in;
  • Alcohol or in hot water (water over 50°C or 122°F).

   

Thermometers are not always accurate so it is important to be watching for other signs that your child might be ill. Also, the degree of a fever does not always indicate how serious illness is, but rather the child’s behavior, overall appearance and other symptoms such as headache, stiff neck, nausea, and vomiting are generally the most important factors. A fever with other symptoms may mean a more serious illness.

    I purchases a new adoric thermometer. It only displays an L in the right side. I have held power button down for 4 seconds, and nothing. I would like it to read in F. Why do I not get a reading on this thermometer????
