indicators are working) and silence alarm;

e. Gradient Variable (Fig. 45.19H): Same as Gradient

10C mode, except that the gradient can be determined by user. Smart mode can be added to

Gradient.

f. Variable: The gradient increases by 5°C beyond the

specified gradient until the set temperature is

reached. When the infant’s temperature deviates

from set point after having reached the target

temperature, the gradient returns to the specified

gradient.

g. Monitor Only (Fig. 45.19J): Displays the patient

temperature without heating or cooling or circulating the water.

The cooling system is activated by pressing Temp

Set and setting the target temperature, followed by

pressing the mode selector. To change to Monitor

Only, press the appropriately labeled button

(Fig. 45.19J).

WBC with Gradient Variable Mode is

Described Below

Technique

(1) Place the Blanketrol III unit in the patient area,

accessible to the correct power source.

(2) Check the level of the distilled water in the reservoir. Lift the cover of the water fill opening

and check that the water is visibly touching the

strainer (Fig. 45.18J).

(3) Check that the power switch is in the off position (Fig. 45.18B).

(4) Insert the plug into a properly grounded receptacle.

(5) Lay the hyper-hypothermia blanket flat (Fig.

45.20) with the hose routed, without kinks,

toward the unit.

(6) Cover the blanket with a dry sheet or disposable

cover (Fig. 45.20), if single patient use blanket

such as MAXI-THERM (Cincinnati Sub-Zero

Products, Inc., Cincinnati, Ohio) is used.

(7) Connect the blanket to the Blanketrol III unit:

Attach the quick-disconnect female coupling of

the connecting hose to the male outlet coupling
