Rectal Predictive
When used correctly, the monitor produces an accurate rectal temperature measurement
in less than 13 seconds.
1.
Remove the temperature probe from the probe holder.
The temperature probe runs a self-test, displaying ‘188.8’ for a few seconds. When it
is ready for use, a double tone sounds, the temperature window clears, and then rEC
appears in the message window.
2.
Load a probe cover onto the probe.
3.
Apply a thin coat of water-based lubricant to the tip of the probe cover.
4.
Separate the patient’s buttocks with one hand.
5.
Insert the probe tip 1.5 centimeter (5/8-inch) inside the rectal sphincter. Tilt the probe
slightly to ensure good tissue contact, and keep the buttocks separated throughout
the duration of the measurement.
During the measurement period, the temperature window displays a “walking box”—
a box with the sides illuminated sequentially. When the measurement is complete,
the monitor sounds a tone and displays the measurement in the temperature
window.
The monitor displays the temperature reading for one minute.
6.
Remove the probe.
7.
Eject the probe cover by pressing the ejection button, and hygienically dispose of it.
8.
Return the probe to the probe well.
Note
For rectal temperatures, use only the rectal probe (red ejection button) and the
red probe well.
WARNING Use extreme care to avoid any risk of bowel perforation.
Note
If a probe position error occurs during the temperature determination, the
temperature display alternates between the measured temperature and ‘P’.
WARNING If the probe becomes contaminated, follow the instructions under
