Non-mercury thermometers have scale divisions equal to mercury thermometers. Most range from 0.5° to 1° C. Accuracy limits for non-mercury thermometers below 150° C are also compatible with mercury thermometers; accuracy is typically ± 1° – 2° C.
Then, do you add a degree when taking temp under tongue?
Should I add a degree to oral (under the tongue) and axillary (under the arm) readings? Yes, for the most accuracy. Rectal temperatures are considered most accurate indication of the body’s temperature. Oral and axillary temperature readings are about ½° to 1°F (.
Keeping this in consideration, how do you shake down a mercury free thermometer?
How long do you leave in a mercury free thermometer?
ORAL TEMPERATURE
After shaking the mercury down, place the thermometer under the child’s tongue, with the bulb toward the back of the mouth. Tell your child to keep the lips firmly closed, but not to bite the thermometer. 3. Leave the thermometer in place for 3 minutes.
Is 37 a fever?
The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the “normal” body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness.
Is 37.5 a fever in adults?
An adult probably has a fever when the temperature is above 99°F to 99.5°F (37.2°C to 37.5°C), depending on the time of day.
What is a normal body temperature chart?
Body temperature chart for adults
| Body temperature chart for adults | ||
|---|---|---|
| Hypothermia | < 35.0° | < 95.0° |
| Normal | 36.5° – 37.5° | 97.7° – 99.5° |
| Hyperthermia (low-grade fever) | > 38.3° | > 100.9° |
| Hyperpyrexia (high fever) | > 41.5° | > 106.7° |
What temp is considered a fever?
Normal body temperature ranges from 97.5°F to 98.9°F (36.4°C to 37.2°C). It tends to be lower in the morning and higher in the evening. Most healthcare providers consider a fever to be 100.4°F (38°C) or higher. High fevers may bring on seizures or confusion in children.
Which is more accurate digital thermometer or mercury thermometer?
Digital thermometers provide better accuracy
In fact, some digital thermometers also include thermocouple sensors on the probe that have been measured and calculated to provide very high accuracy and without the need for calibration like mercury thermostats.
