Thermometers

It is important to fully insert the thermometer into the sheath such that the thermometer’s probe TIP is within roughly 1mm of the sheath end. If too large a gap is left the sheath will fold over the tip which may result in puncture. Make sure the top cover is removed first, then the bottom cover. On flexible tip thermometers it is helpful to hold the thermometer a bit closer to the probe end to minimize flex when peeling off the top and bottom paper covers.

Core body temperature most closely approximates the temperature obtained through rectal measurement. Oral temperatures will generally run 1 degree lower than rectal temperatures. Axillary (under the arm) temperatures will generally run 1 degree below oral (2 below rectal). Remember, 98.6 is an average of the patient population. Your average body temperature might vary by up to 2 degrees from that.  And while not as volatile as blood pressure, your temperature will vary throughout the day.
