Familiarize yourself with the display panel and button functions before proceeding with temperature measurements, ensuring a smooth and accurate operation. Proper initial setup is vital for reliable performance.
Taking a Tympanic (Ear) Temperature
For accurate tympanic measurements, select the ear mode on the Welch Allyn SureTemp Plus. Gently pull the ear upward and outward – for adults – or downward and back – for children – to straighten the ear canal.
Insert a fresh probe cover onto the thermometer probe; this is essential for hygiene and accuracy. Carefully insert the probe tip into the ear canal, ensuring a snug but comfortable fit. Avoid forcing the probe.
Press and hold the measurement button until a beep confirms the reading is complete, typically within one second. The temperature will then be displayed on the screen.
Remove the probe and discard the used probe cover. Always use a new probe cover for each patient to prevent cross-contamination. Note that factors like earwax or canal inflammation can affect reading accuracy.
Taking an Oral Temperature
To obtain an oral temperature with the Welch Allyn SureTemp Plus, ensure the patient has not eaten, drunk, or smoked for at least 15-30 minutes prior to measurement. Select the oral mode on the device.
Attach a fresh probe cover – specifically a blue-tipped probe – to the thermometer. Gently lift the patient’s tongue with the tip of their tongue and position the probe tip under the tongue, towards the back of the mouth.
Instruct the patient to close their lips gently around the probe, avoiding biting down. Hold the thermometer in place and press the measurement button until a beep indicates completion.
Read and record the temperature displayed on the screen. Discard the used probe cover immediately after use. Oral temperatures may be slightly lower than tympanic or rectal temperatures.
Taking a Rectal Temperature (If Applicable)
Rectal temperature measurement, while accurate, should be reserved for situations where oral or tympanic measurements are not feasible. Use a dedicated rectal probe – typically with a brown or distinctively marked tip – and always apply a water-soluble lubricant to the probe cover.
Position the patient appropriately, either lying on their side with knees drawn up towards the chest, or in a lithotomy position. Gently insert the probe no more than 1-1.5 cm into the rectum.
Hold the thermometer securely in place and activate the measurement. A beep will signal completion. Carefully remove the probe and discard the probe cover immediately.
Rectal temperatures are generally 0.5-1°C (0.9-1.8°F) higher than oral temperatures. Document the measurement method clearly. Strict hygiene protocols must be followed to prevent cross-contamination.
