Patient Control - Gaymar Medi-Therm III Mode D'emploi

Medi-Therm III
®
NOTE: In BLANKET CONTROL mode, if the machine
senses a patient probe temperature below 29°C or
above 40°C, the CHECK PATIENT alert will light and
audible alarm will sound. Therapy will continue. When
this occurs:
• Check the patient's temperature.
• Check also to determine if the patient probe
has become dislodged, an incorrect probe
is being used, or the probe has become
defective. See Troubleshooting (pp. 12-13).
The CHECK PATIENT alert will turn off and
the audible alarm will silence when the patient
temperature returns to the range of 29°C to
40°C.

6.2 PATIENT CONTROL

When operating in the PATIENT CONTROL mode, the
Medi-Therm III automatically regulates the patient's
temperature to the selected SET POINT. The machine
constantly compares actual patient temperature with
the SET POINT value, and automatically adjusts the water
temperature so that the desired patient temperature is
achieved.
To operate in PATIENT CONTROL mode:
1. Perform all start-up procedures (pp. 6-7).
2. Insert sensing end of patient probe into
patient and tape securely to prevent accidental
dislodgment.
3. Insert plug end of patient probe into PATIENT PROBE
jack. Make sure probe plug is fully seated.
Use only Gaymar probes or equivalent YSI
400 series probes approved for use with
medical devices. If in doubt that the correct
probe is being used and is operating properly,
perform a PROBE CHECK test (p. 13).
4. Press the PATIENT CONTROL button. The upper
window on the top of the PATIENT CONTROL
button will light.
NOTE: To prevent accidental triggering of the
CHECK PATIENT alert, place probe in patient and
wait for patient temperature to stabilize before
pressing PATIENT CONTROL button.
The WATER display will indicate water
temperature. The PATIENT display will indicate
patient temperature. The SET POINT temperature
will indicate the default temperature (37°C)
PATIENT CONTROL
at start-up, until selecting the SET POINT
temperature in step 5.
5. Adjust the SET POINT display to the prescribed
patient temperature setting (30°C to 39°C). See
page 5, SET POINT CHANGE.
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 of the SET POINT
temperature) both the WARMING and COOLING
lights will turn off indicating that the desired patient
temperature is being maintained.
6. The rate of patient cooling and warming is user
adjustable through the use of the CONTROL OPTION.
The CONTROL OPTION defaults to RAPID when
PATIENT CONTROL mode is entered. Select a
different CONTROL OPTION by pressing the PATIENT
CONTROL button again.
When COOLING the patient:
RAPID - the coldest water is used for
cooling - as low as 4°C. This may not be
the most comfortable setting for the patient.
MODERATE - water temperature is limited
to 15°C below the patient's temperature. This
will provide an improved comfort setting to the
patient.
GRADUAL - water temperature is limited to
10°C below the patient's temperature. This will
provide an improved comfort settting to the
patient.
When WARMING the patient*:
RAPID - the highest allowable water
temperature is used for warming - as high as
41°C. This is the fastest warming mode the
machine can provide.
MODERATE - the patient's temperature will
increase at a rate of 1°C in a period of 3 hours
(0.33°C/Hr).
GRADUAL - the patient's temperature will
increase at a rate of 1°C in a period of 6 hours
(0.17°C/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.
