Medi-Therm

Check the integrity of the skin
according to department protocol when
regulating temperature with external
devices. Frequency of assessment and
documentation will vary depending upon
the individual response of the patient.
Failure to monitor patient
may result in skin damage or
inappropriate patient temperature.
•
If the patient probe senses an abnormal
patient temperature (below 29°C
[84.2°F] or above 45°C [113°F]),
therapy will stop, the
CHECK PATIENT
PROBE
alert will light and an audible
alarm will sound.
This condition may indicate
the patient probe has become
dislodged, an incorrect probe
is being used, or the probe has
become defective (see
Alerts,
pp. 17-18).
NOTE: The
PATIENT
temperature display will
begin to flash, the
ALERT
LED will flash
and the audible alarm will toggle when
the patient's temperature deviates
by 1.0°C (1.8°F) or more from the
programmed warming rate selected.
NOTE: When using the rate controlled Auto
Moderate or Auto Gradual modes for
warming; switching to other modes,
e.g. Auto Rapid or Manual, or changing
the temperature set point during the
therapy will cause the Medi-Therm
to reset the therapy. This may impact
the overall duration of the therapy
depending on when in the hourly cycle
the mode is interrupted. The therapy
time duration is also dependent on
the patient's temperature at the time
the Auto Moderate or Auto Gradual
modes are re-selected.
Modes of Operation / Automatic Mode
Adjust the
SET POINT
display to the prescribed
patient temperature setting by pressing the “
∇
” or
“
∆
” button to decrease or increase the
SET POINT.
NOTE: When the Medi-Therm III machine is turned
on, the machine set point defaults to 32°C
(89.6°F) when
MANUAL
mode is selected or
37°C (98.6°F) when
AUTO
mode is selected.
Once a
SET POINT
temperature for a mode
has been selected, it is retained for that mode
until the
SET POINT
temperature is changed
or the machine has been turned off.
The
SET
POINT
temperature in one mode does
not affect the
SET POINT
temperature
in another mode.
The unit will heat or cool as required to bring the
patient temperature to the
SET POINT.
The
STATUS
display will indicate
WARMING
or
COOLING
while the
machine is heating or cooling the patient. When the
patient temperature stabilizes (within 0.5°C [0.9°F]
of the
SET POINT
temperature), both the
COOLING
and
WARMING
displays will turn off indicating that the
desired patient temperature is being maintained.The
rate of cooling and warming is user adjustable through
the use of the
CONTROL OPTION.
The
CONTROL OPTION
defaults to
RAPID
when
AUTO
mode is entered. Select a different
CONTROL OPTION
by pressing the
AUTO
button again.
When
COOLING
the patient:
RAPID -
the coldest water is used for cooling -
as low as 4°C (39°F). This may not be the most
comfortable setting for the patient.
MODERATE -
Water temperature is limited to
15°C (27°F) below the patient's temperature.
This will provide an improved comfort setting
to the patient.
GRADUAL -
Water temperature is limited to
10°C (18°F) below the patient's temperature
.
This will provide the optimal comfort setting to
the patient.
When
WARMING
the patient:
RAPID -
the highest allowable water temperature
is used for warming - as high as 42°C (107.6°F).
This is the fastest warming mode the machine
can provide.
MODERATE -
The patient temperature will
increase at a rate of 1°C (1.8°F) in a period of
3 hours (0.33°C/Hr [0.6°F/Hr]).
GRADUAL -
The patient temperature
will increase at a rate of 1°C (1.8°F) in
a period of 6 hours (0.17°C/Hr [0.3°F/
Hr]).
When using AUTO MODERATE and AUTO
GRADUAL for patient warming,
NO MANUAL
INTERVENTION
is required once the patient set
point temperature has been selected for warming.
