Making Body Temperature Measurements
FlexTEMP System Jackets are mandatory for use with the temperature sensor when making
esophageal or rectal (body) temperature measurements. Before making temperature
measurements at esophageal or rectal sites, cover the sensor according to the steps below.
Placing the Temperature Sensor in a Jacket
FlexTEMP System Jackets are sterile polyurethane sensor covers and should be handled accord‐
ingly. For optimal storage, jackets should remain sealed in sterile packs in closed cabinets where a
moderate temperature and low humidity are maintained. When placing the sensor in a jacket,
ensure that the sensing tip is fully inserted and that the jacket tabs extend over the patient seg‐
ment of the temperature sensor, as described in the steps below.

Expression MR400 Instructions for Use
Use of FlexTEMP System Jackets are mandatory when using the sensor for body (i.e.,
esophageal or rectal) site temperature measurements. Failure to comply may result in
Always use a new jacket if a different placement area is desired. Once the sensor has
been used for esophageal or rectal placement, do not change the location unless a new
jacket is installed as patient injury or infection could result.
Do not reuse a FlexTEMP System Jacket, as they are designed for single-use only.
Failure to comply may result in patient infection.
Carefully uncoil the sensor, using care to avoid knotting or kinking
Clean and disinfect the sensor; see Cleaning, Disinfecting, and
Inspecting the Accessories, on page 14‐7, for details.

Insert the patient segment of the sensor into the jacket. Grasp the
jacket tabs then carefully pull the jacket completely over the
patient segment of the sensor.
