Q & A - FEVER

What is Fever?

Fever is one of the body's defence mechanisms. When bacteria or viruses get into your body and cause it to malfunction, the body goes on the defensive and your immune system is activated. When this happens, a central nerve in the brain allows the heat generated inside the body to be turned up from the usually constant level. This higher temperature level increases the metabolism and prevents the increase of pathogenic agents.

What is the “normal temperature”?

Normal temperature" is usually around 37 °C (98,6 °F). However, normal temperature is not the same for every individual. Temperature can vary with age, and even time of day. Usually it is lowest in the morning, highest in the afternoon and somewhat lower at bedtime.

Why measure body temperature?

It is of great medical importance to measure body temperature. The reason is that a number of diseases are accompanied by characteristic changes in body temperature. Likewise, the course of certain diseases can be monitored by measuring body temperature, and the efficiency of a treatment initiated can be evaluated by the physician. Fever is a reaction to disease-specific stimuli, where the set point of the temperature control centre is varied to promote the body's defences against the disease process. Fever is the most common form of pathological (disease- related) elevation on body temperature.

How accurate are thermometer measurements?

Essentially a distinction must be made between the technical accuracy of the thermometer itself and the clinical accuracy in use in taking a temperature. The former is determined under idealized conditions to guarantee the quality of the instrument, taking the relevant technical standards into account. An accuracy of +/- 0.1°C can be considered state of the art for high-grade thermometers. The user must not confuse technical accuracy with this accuracy in use. The human body temperatures described here, which depend on the measurement location and time, are due to physiological causes and are not due to a thermometer malfunction.

Where should I take the temperature?

Rectal

The most reliable core temperature is obtained by inserting a thermometer into the rectum (rectal measurement). This measurement is accurate and has low scattering in the results. The normal range is approximately 36.2oC -37.7oC.

Vaginal

In women, vaginal temperature measurement yields a slight underestimate of temperature by an average of 0.1°C to 0.3°C in comparison with a rectal measurement with comparable stability.

Ear

Ear thermometers measure the temperature of the eardrum with an infrared sensor. The tip of the thermometer is simply positioned in the ear channel and results are obtained in one second! Next to its convenience this method is very reliable if accuracy can be proven by a clinical validation. Well-designed ear thermometers perform very accurately without great scattering in results. An optimised tip shape is the basis for reliable data obtained with infants and babies.

Oral

The oral measurement can be performed as buccal measurement (in the cheek) or as a sublingual measurement (under the tongue). Both measurements underestimate the rectal temperature by approximately 0.3°C - 0.8° C, with the sublingual measurement being preferable to the buccal.

Forehead

Forehead thermometers offer the least intrusive and therefore most comfortable way to measure body temperature. Simply place the thermometer onto the patient's forehead and an infrared sensor detects the peak reading, while a second sensor measures the ambient temperature. The difference in these readings is analysed, and according to clinically established offsets, a body temperature reading is determined and displayed on the LCD.

Armpit

Body surface temperature measurements used clinically in practice are in the arm pit (axillary measurement) and in the groin. In both cases the respective limb is pressed against the body in order to reduce any ambient temperature influence. However, this is successful only to a limited extent with the disadvantage that the measurement time is long. In adults, the axillary measurement is lower than the rectal by approximately 0.5°C to 1.5°C! In infants, these underestimates in comparison with the rectal temperature are much smaller.

What is important when taking temperature?

Essentially, it is true that the measured body temperature always depends on where it is measured. Therefore, contrary to popular consensus, there is no simple "normal temperature. Furthermore, a healthy person's body temperature will vary with activity and time during the day. In a rectal temperature measurement, a typical temperature difference of 0.5°C between the higher evening temperatures is physiological. Body temperature is typically elevated after physical activity. Roughly speaking, a distinction is made between a core temperature and a surface, where the surface temperature is measured at the skin surface and is a mixed temperature between the body's core temperature and the ambient temperature. The core temperature is measured by inserting a thermometer into a body cavity, which yields the temperature of the mucous tissue.

Quick Guide

How to use the RA600 Infrared Ear Thermometer

• To achieve accurate readings, make sure a new, clean probe cover is in place before each measurement and the ear canal is clean.
  • Install the probe cover by clockwise rotating then fix it.
  • Remove the probe cover by anti-clockwise rotating then releasing it.
• Press the “On/Off/Memory” button. The thermometer is ready for use after the ear icon is flashing and two beeps are sounded.
• Gently pull the ear back to straighten the ear canal and snugly position the probe into the ear canal, aiming towards the membrane of the eardrum to obtain an accurate reading.
  • Before measurement, correct installation of the probe cover ensures accurate measurement.
  • Replace the probe cover after each use to ensure an accurate reading and avoid cross contamination.
  • This thermometer must only be used with Rossmax probe covers, other covers can lead to inaccuracy. If running out of probe covers, please contact with the original seller or distributor for buying new probe covers.
• Measuring the ear temperature: Use the index finger to trigger. Press “Start” button, a long beep will be sounded when measurement is done.
• Power Off: Device will automatically shut off if left idle for more than 1 minute to extend buttery life. Or press “On/Off/Memory” button for at least 3 seconds to turn the device off.
• Fever alarm: the measuring temperature is higher than 37.5°C (99.5°F), the display will flashing and 4 short beeps will be sounded. The measuring temperature is higher than 42.2°C (108.0°F), the display will show “Hi“and 4 short beep will be sounded.
  • It is recommended that you measure 3 times with the same ear. If the 3 measurements are different, select the highest temperature.
  • To avoid the risk of cross contamination, please clean the probe according to “Clean and Storage“section after each use.

Scanning Mode

If you continuously obtain different measurement results, it is recommended that you use Scanning Mode to measure.

Measuring the ear temperature: Use the index finger to trigger, press and hold the “Start” button for 3 seconds to take measurement. During the measuring process, gently pivoting the probe side-to-side to view the entire ear canal or in order to find the highest temperature. Release the “Start” button until hearing a long beep sound and the measurement is completed.

Cautions

1. Besides the oral temperature, the body temperature measured by ear may be different from measurements taken by rectal or axillary. Therefore, there is no any meaning to compare them. Take the temperature periodically to find out the normal ear temperature reading, then use that reading as the basis for comparison with any measurement taken when you suspect a fever.
2. Keep the unit dry and away from where it might be exposed to moisture, liquids, direct sunlight, high temperature, high humidity, or excessive dust.
3. This device is not shock-protected. Do not drop, heavily pressure the unit or fall from high place.
4. Wipe the device clean before storing.
5. When taking the device from storage below or above 10~ 40°C (50~104°F), place it in 10~ 40°C (50~104°F) temperature range for at least 30 minutes before use.
6. Be sure to consult a doctor if you feel that your health is in poor condition.

Cleaning and storage

The probe is the most delicate part of the thermometer. Use with care when cleaning the lens to avoid damage.

• Please use the cotton swab with the Alcohol to clean the lens (on the inside of the probe).
• Allow the probe to fully dry for at least 5 minutes.
  • Please check the device if it falls and damages. If you can’t make sure of it, please send the complete device to the nearest retailer for checking.
  • Keep the unit dry and away from any liquid and direct sunlight. The probe should not be submerging into liquids.
