Introduction:

Glass thermometers have been long used as valuable tools in measuring temperature, especially in medical settings and at home. They are mercury-free, accurate, and can provide readings relatively quickly. In this article, we will explore three simple ways to use a glass thermometer to measure body temperature: orally, under the arm (axillary method), and rectally.

1. Oral Method:

The oral method is the most common way of using a glass thermometer. To obtain an accurate reading through this method, follow these steps:

a. Clean the thermometer with rubbing alcohol or soapy water.

b. Shake the thermometer gently until the liquid drops below 96°F (35.5°C).

c. Place the bulb of the thermometer under your tongue and close your mouth.

d. Hold the thermometer in place for at least two minutes without talking or moving your lips.

e. Remove the thermometer, read and note your temperature at eye level.

f. Clean the thermometer in-between uses.

2. Axillary Method:

Though less accurate than other methods, taking one’s temperature under the arm is an easy alternative, especially for children:

a. Clean the thermometer as mentioned earlier.

b. Shake it to ensure it’s below 96°F (35.5°C).

c. Lift your arm and tuck it against your body for a few seconds to establish a stable temperature.

d. Place the bulb end of the thermometer into your armpit and lower your arm to hold it snugly in place.

e. Wait for three minutes before removing the thermometer.

f. Record the reading at eye level and clean it afterward.

3. Rectal Method:

Rectal temperatures are usually around 0.5°F-1°F higher than oral readings, making this method extremely accurate:

a. Preparation is essential – lubricate more than half an inch of the bulb end of the thermometer with petroleum jelly.

b. Shake the thermometer as described and clean it before starting.

c. Lie on your side with knees pulled up towards the chest or, for a child, lay face-first on the lap of a guardian.

d. Gently insert the lubricated thermometer straight into the rectum (about ½-1 inch deep), and hold it in place during the measurement.

e. Wait for two minutes, remove, and note down your temperature reading at eye level.

f. Clean the thermometer thoroughly before placing it in storage.

Conclusion:

Glass thermometers are a reliable tool for measuring body temperature. With these three simple methods – oral, axillary, and rectal – you can effectively monitor temperatures without much hassle. As always, ensure proper hygiene and care in using the instrument and consult a healthcare provider if your temperature readings consistently indicate fever or illness.
