How to take body temperature in adults
It is important that you know how to take a temperature because this helps to identify fever and properly treat diseases. The normal temperature range is 96.8 to 100.4 ° F (36 to 38 ° C). To determine what your temperature is normal, take it when you are well.
Each time the temperature is taken, record it. Record the date, time, and any symptoms you have.
No Touch Thermometer offers a unique solution to this problem. Many No touch thermometers feature a patented switchable dot-circle laser. The circle mode of a built-in laser thermometer creates a 12-point circle that clearly indicates the target area being measured. In laser point-to-point mode alone, it marks the center of the measurement area.
What are the Different Types of Thermometers?
There are several types of thermometers. The following types are recommended for safe use:
- Multipurpose digital thermometer. This can be used in the mouth (buccal), in the rectum (rectal) or under the arm (axillary). Always label multipurpose digital thermometers. Don’t use the same multipurpose digital thermometer to take temperature in different ways.
- Temporal artery thermometer. This is placed on the forehead. Collects the heat that comes from the temporal artery, that crosses the forehead.
- Tympanic thermometer. This type is placed in the ear canal. Registers the heat emanating from the eardrum.
Do not use the following thermometers:
- Mercury-filled glass thermometers. The glass could break. This is dangerous for your health and the environment.
- Temperature strips. They are not always accurate and are not currently recommended.
Type of thermometer to use
Axillary measurement is the least reliable method. It should only be used as an assessment tool.
Always remember that:
- Rectal and temporal artery temperatures may be slightly higher.
- Tympanic and axillary temperatures may be slightly lower.
General indications
Take your temperature the same way each time you check it. Different methods can provide readings different. The only way to know if your temperature is increasing or decreasing is by using the same method each time.
