Beurer OT 20 - Basal Thermometer Manual

Intended Use

The basal thermometer is a special digital thermometer designed to measure the basal temperature in women of childbearing age as an aid in ovulation prediction to aid in conception (not to be used for contraception). The maximum temperature measured with the sensor is saved until the next measurement. The thermometer is only intended to measure basal temperature. It is not intended to evaluate values or detect ovulation, or to diagnose fever or other contagious disease.
Transferring the measurements to the Ovy app enables fertile and non-fertile days in the cycle to be predicted, as well as periods. It can be used for oral, rectal or vaginal measurement.

Parts and Controls

To Use

NOTE: A Basal Thermometer is used to chart basal body temperature (BBT), the basis of a fertility chart. Basal temperature is the lowest normal body temperature after waking in the morning (before getting up, talking, moving around, eating, drinking, or smoking).

1. Clean the thermometer before and after each use with a soft cloth and isopropyl alcohol diluted with water. Wipe with a clean, damp cloth and let dry.
   NOTICE: Do not soak the product or sterilize by boiling or steaming it.
2. Press the On/Off Button; the thermometer will beep.
   The thermometer will carry out a self-test for about 2 seconds. During the selftest all segments of the LCD Display will activate briefly.
   
3. The product will then briefly display the reference reading of 97.70°F (36.5°C) and then "Lo" with a flashing "°F", which indicates the thermometer is ready for use.
4. The last measurement is stored automatically on the device. To view the last stored measurement, press and hold the On/Off Button while the thermometer is off. After about two seconds, the previously recorded temperature measurement will display as long the On/Off Button is held. Release the On/Off Button to continue use.
5. Promptly begin temperature measuring. Check section below for different measuring areas. When the thermometer beeps four times, temperature measuring is complete. Note that it may take up to three minutes for the temperature to stabilize and record a reliable measurement, therefore a measuring time of 3 minutes is recommended. A measurement duration of at least 30 seconds should be maintained.
6. If the measured temperature is higher than 109.39°F (43°C), the display will show "Hi °F". If the temperature is lower than 89.60°F (32°C), the display will show "Lo °F".
7. Press the ON/OFF Button to turn off the thermometer.
   NOTE: The thermometer will shut off by itself after about 10 minutes of nonuse.

Tips for correct use:

• Influencing factors, such as alcohol consumption or unusual body signs, fever, disrupted sleep, your mood or extreme or unusual physical activity may distort your basal temperature and make it unusable for evaluation.
• Do not eat and avoid physical exertion before measurement.
• You should have slept at least 4 hours before the measurement. An unusual lack of sleep may distort your basal temperature. In that case, enter the amount of sleep in the Ovy app or your basal temperature chart or mark the measurement as "disrupted sleep".
• Take your temperature as soon as you wake up and before you get out of bed.
• The most accurate reading is taken at the same time every morning. Your resting (basal) temperature will measure low and stable during the first weeks of your monthly cycle. Recording your basal temperature on a regular basis will document a temperature fluctuation pattern in your monthly cycle.
• Do not change the thermometer or measurement area during your cycle. If you change the thermometer or the measurement area, mark it as a disruption. Reliable evaluation is no longer guaranteed for the current cycle.
• The thermometer does not detect ovulation or evaluate any measured values.

Measuring Areas

Do not talk, eat, drink, bathe, exercise, or smoke before a temperature measurement.

Oral Temperature Method

• Place the Probe Tip under the tongue as near as possible to a heat pocket, to the left or right of the root of your tongue, and keep the mouth closed (see Fig. 1). The Probe Tip must have good contact with tissue.
  
• Close your mouth and breathe calmly through your nose during measurement.

Rectal Temperature Method

• Apply a water-soluble lubricant to the Probe Tip. Do not use petroleum jelly.
• Gently insert the Probe Tip into the rectum approximately ½ inch (1 cm). Normal rectal temperature is 97.90°F (36.6°C).
  NOTE: Do not use a thermometer that has been used for rectal temperature measuring for oral temperature measuring.

Vaginal Temperature Method

• Gently insert the Probe Tip into the vagina approximately ½ inch (1 cm).
  NOTE: Do not use a thermometer that has been used for rectal temperature measuring for, vaginal or oral temperature measuring.

The Ovy App

The free downloadable Ovy app enables you to record your entire cycle and keep an eye on it at any time on your smartphone. Ovy is designed for use specifically with Ovy by Beurer basal thermometers by woman who want to conceive. It is NOT to be used for contraception. The app is available for download in the Apple App Store and Google Play.

How does the app work?

The Ovy app works out your cycle automatically, without pen and paper. This includes your period, ovulation and your fertile and non-fertile windows. To do this, take your temperature when you wake up in the morning and enter the value (with two decimal places) in the Ovy app. To make the prediction even more accurate, add other body signals each day. You should ideally start recording this on the first day of your period; i.e. the first day of your menstrual cycle. However, you can also start recording on any day in your cycle. It is important that you record when potential external temperature influences such as a fever, consumption of alcohol or a lack of sleep have occurred.
You can also enter your basal temperature, body signals and influencing factors at a later time, but the temperature measurement should be taken on the relevant day. The Ovy app is based on a self-learning algorithm. This means that the more often you enter your basal temperature, the more accurately Ovy will be able to predict your fertile days and your next period.

The Female Reproductive Cycle

THE ROLE HORMONES PLAY IN OVULATION

At the beginning of each menstrual cycle, the pituitary gland secretes a hormone called FSH, or Follicle Stimulating Hormone, that acts upon the ovaries to prepare for ovulation. As one or more follicles in an ovary prepare for ovulation, they secrete another hormone called estrogen that prepares the uterus for pregnancy by causing the inner liming of the uterus to thicken. Estrogen also causes some glands in the cervix to secrete a mucus discharge that is necessary for fertility. This mucus changes the environment in the vagina to make it more favorable to sperm life and provides a medium in which the sperm move upward into the uterus. This mucus typically starts as a sticky substance, but during the time of fertility becomes more liquid and plentiful, usually attaining a consistency very similar to raw egg whites. Sometimes the mucus becomes so watery that it will no longer stretch like raw egg whites, but continues to produce sensations of lubrication or wetness at the outer lips of the vagina.

WHAT IS OVULATION

At ovulation, the ovarian follicle releases an egg which is picked up by one of the Fallopian tubes and transported toward the uterus. For pregnancy to occur, sperm must fertilize the egg in the Fallopian tube within 24 hours of ovulation. After 24 hours, the egg disintegrates and cannot be fertilized.

AFTER OVULATION

The ovarian follicle that released the egg secretes another hormone called progesterone. This hormone suppresses further ovulation. Progesterone continues to build the vaginal lining and maintains it after ovulation. It also causes your basal temperature to rise and the cervical mucus to thicken so much that it appears to dry up. Ovarian progesterone secretion continues for approximately 14 days. When it stops, the inner lining of the uterus can no longer be maintained, so it is discharged in a process called menstruation (your period), and the menstrual cycle starts again.

HOW TO DETERMINE THE DATE OF OVULATION

By charting basal temperatures upon waking, you can observe the patterned rise in temperature. A temperature dip towards the mucous pattern sometimes indicates the day of ovulation. The first day the temperature rises could indicate ovulation. The purpose of the chart is to help plan future intercourses and assist documentation of unique fertility patterns.

ORAL TEMPERATURE RANGES BEFORE AND AFTER OVULATION

Your basal temperature before ovulation is usually in the range of 96.50°F to 98.10°F (35.8 - 36.7°C). After ovulation, the basal temperature rises about 0.4°F to 0.9°F (-17.5 - -17.3°C) and stays in that higher range until the beginning of the next menstrual period. The highest probability of conception is during the days immediately prior to ovulation as well as on the day of ovulation itself.

OTHER IMPORTANT INFORMATION

Notation of any changes, in addition to your temperature pattern, will assist your physician or family planning counselor in providing you with proper guidance. It is commonly suggested that couples who have had difficulty in achieving pregnancy should not have intercourse more than once a day nor on consecutive days, in order to maintain satisfactory quantities of sperm. The most fertile time continues through the first day of drying up of the mucus or the first day of temperature elevation, whichever comes later. Maintain your temperature record daily. If pregnancy occurs, the basal temperature will remain elevated for several months. A temperature pattern that remains elevated for 21 days is a good indicator of pregnancy. If you do not become pregnant after six months, see your doctor. If you believe you are pregnant, see your doctor.
