When will we use the Clinical Thermometer
Clinical thermometers, also known as medical thermometers or doctors’ thermometers, are used to take body temperatures in humans and animals. Traditional thermometers use thermometric liquids (i.e., mercury) to measure temperature in body cavities — orally, rectally, vaginally — or at other points, such as the underarm. Many newer thermometers use infrared radiation to record temperature at alternative points, such as the eardrum (tympanic) or forehead.
As the Mercury thermometer, It is no longer considered safe, especially for use in children. So more and more hospital choose infrared thermometer or ear thermometer. It can ensure accuracy and test fast.
There are two situation mainly use for Clinical thermometers.
- Human Body Temperature
Human body temperature is measured in order to reflect relative health. A significantly elevated (or sometimes lowered) temperature beyond the normal range can indicate illness. Clinical thermometers typically measure a range from 95 to 109 degrees Fahrenheit (or 35 to 40 degrees Celsius). Average normal human temperatures are usually in the 97 to 99 degree range, though fairly significant variations are possible among individuals. Temperatures of 100 degrees or more indicate fever; for infants, fevers of 100.4 degrees or more need immediate medical attention to rule out serious infection.
- Predicting Female Fertility
Women can use thermometers to help predict fertile periods. Basal body temperature, or BBT, is the lowest (baseline) temperature reached while resting. BBT is taken around 6 a.m. and after at least five hours sleep. BBT typically spikes at least 0.4 degrees over a 48-hour period when ovulation has occurred. BBT remains elevated until menstruation begins; if pregnant, BBT remains slightly elevated. A woman who uses this method to predict ovulation will need to chart temperatures for several cycles to predict optimal fertility. Once she has ovulated, it is likely too late to engage in intercourse to achieve conception during that cycle; however, she can use BBT to confirm she is ovulating, and to familiarize herself with her cycle.
