Difference Between Oral and Rectal Thermometer (With Table)

In today’s lifestyle, virals and fevers are normal due to pollution and weak immune systems. So the basic medical kit is essential in homes, offices, and schools. The most common uneasy situation faced by most human beings is abnormal body temperature which is also known as fever. To measure the seriousness of fever, a thermometer is discovered. They can be of different types, and to know about them, they are discussed below.

Oral vs Rectal Thermometer

The difference between an oral thermometer and a rectal thermometer is based on the procedure of its usage. Both of them are used for checking body temperature but in different ways. The oral thermometer is used by checking the temperature from the mouth, whereas the rectal thermometer is placed in the rectum to check the body temperature of babies.

The oral thermometer is a device which is invented to serve the purpose of checking body temperature to know if it’s fluctuating and if it is, then when could be the possible reasons for that. The oral thermometer is used by checking the temperature from the mouth.

The rectal thermometer is also a device which got invented to serve the purpose of measurement of body temperature. It is necessary to know the reasons and measurements of uneasy feelings in the body. It is made to serve kids who are under 3 years, and as they are incapable of express their feelings and know the difference between good or bad, It is important for them.

What is Oral Thermometer?

The oral thermometer is a device which is invented to serve the purpose of checking body temperature to know if it’s fluctuating and if it is, then when could be the possible reasons for that. The oral thermometer is used by checking the temperature from the mouth. The oral thermometer has a longer, thinner tip which provides a larger surface area to the mercury for analyzing the body temperature of a human being.

The difference is color is made so that they can be identified easily, and mistakes can be avoided in terms of appropriate use. The stem of the oral thermometer is in the color blue. There is a difference between the line made, which indicates the normal temperature for both of the thermometers. The normal temperature for the rectal thermometer is around 99.6 degrees. The preferred use of oral thermometers can be adults and kids both.

Mercury is used for the measurement of temperature as it reacts the most with the temperature change and indicates the change accurately in the thermometer. The oral thermometer can be used as an auxiliary thermometer.

What is Rectal Thermometer?

The rectal thermometer is also a device which got invented to serve the purpose of measurement of body temperature. It is necessary to know the reasons and measurements of uneasy feelings in the body. It is made to serve kids who are under 3 years, and as they are incapable of express their feelings and know the difference between good or bad, It is important for them.

The rectal thermometer is designed with precautions so that it can’t hurt you in the rectum. The shape of the rectum thermometer is made blunt, short and with a rounded tip to avoid injury. There is a difference between the line made, which indicates the normal temperature for both of the thermometers.

The normal temperature for the oral thermometer is 98.6 degrees. The rectal thermometers are made for kids under the age of 3 years so that the risk of oral thermometer injuries can be minimized. Any thermometer which is used in the rectum can not be used as oral or auxiliary as it is a chance to get sick because of the bacteria present in the rectum. 

Main Differences Between Oral and Rectal Thermometer

  1. The main difference between an oral thermometer and a rectal thermometer is based on the procedure of its usage. Both of them are used for checking body temperature but in different ways. The oral thermometer is used by checking the temperature from the mouth, whereas the rectal thermometer is placed in the rectum to check the body temperature of babies.
  2. The oral thermometer has a longer, thinner tip which provides a larger surface area to the mercury for analyzing the body temperature of a human being, whereas The rectal thermometer is designed with precautions so that it can’t hurt u in the rectum. The shape of the rectum thermometer is made blunt, short and with a rounded tip to avoid injury.
  3. The difference is color is made so that they can be identified easily, and mistakes can be avoided in terms of appropriate use. The stem of the oral thermometer is in the color blue, whereas The stem of the rectal thermometer is colored in red to avoid confusion.
  4. There is a difference between the line made, which indicates the normal temperature for both of the thermometers. The normal temperature for the rectal thermometer is around 99.6 degrees, whereas the normal temperature for the oral thermometer is 98.6 degrees. 
  5. The preferred use of oral thermometers can be adults and kids both, whereas rectal thermometers are made for the kids under the age of 3 years so that the risk of oral thermometer injuries can be minimized.

Conclusion 

Both of the thermometers have their specified roles to play, and to avoid any confusion, many indicators are placed so that there is no chance of mishappening. Babies are incapable of expressing their feelings, emotion, pain, excitement, or anything, so such tests are important to know as they are healthy and happy. The oral thermometer is a bit unsafe with them as they don’t know what to do or what to not. If they accidentally break it in their mouth, it can be very dangerous, so to avoid such things, rectal thermometers are introduced.
