How To Use A Clinical Thermometer
Ever since the invention of the clinical thermometer, the process of measuring body temperature has become easy and accurate. A doctor does not have to make intelligent guesses about the temperature of the patient. A thermometer is a slim glass tube. On its one end is the bulb. Inside this bulb is liquid mercury. The level of this mercury rises or falls inside the capillary which is placed inside the glass tube. The glass tube is calibrated. The method of using the thermometer is very simple. First of all dip the bulb of the thermometer in freshwater or in a disinfectant. Now hold it firmly and give it few jerks with the hand so that any previous rise in the mercury levels may come down to 95 degrees F. Now place the thermometer inside the mouth of the patient and ask the patient to close his mouth. Wait for one minute. Take out the thermometer from the mouth and note the temperature from the level of mercury which coincides with the calibrations on the tube. Any temperature above 98 degrees indicates it indicates that the person is suffering from general fever or below weakness. Now wash the thermometer and replace it inside the cover.
