on the cooling unit (Fig. 45.18G) and the male

coupling to the female return coupling (Fig.

45.18H) by pushing back the collar of the

female coupling while connecting to the male

coupling, followed by releasing the collar.

(8) Gently pull the connecting hose to ensure a

positive connection, that there are no twists in

the connecting hose, and that the blanket is

flat.

(9) Initiate precooling: Precooling may not be necessary if the infant’s temperature has already

been lowered (e.g., by passive hypothermia during transport).

(a) Switch on the cooling machine (Fig. 45.18B).

(b) Press Temp Set (Fig. 45.19D).

(c) Use the up (∆) or down (∇) arrows by the

side of Set Temp (Fig. 45.19) and set the

temperature to 33.5°C.

(d) Press Manual Control (Fig. 45.19B).

(e) Listen for the compressor to activate.

(f) Check the water flow indicator (Fig. 45.18,

F) to confirm that water is circulating.

(g) Place the infant on the blanket (Fig. 45.20).

(h) Place patient temperature monitoring probes.

Rectal Temperature Sensor

(1) Mark a 400 series probe at 6 cm from the tip

with tape/indelible pen (Fig. 45.2).

(2) Insert rectal probe 6 cm into the rectum, and

secure to leg using DuoDERM/Tegaderm and

tape, as described in E (Fig. 45.2).

Esophageal Temperature

(1) Measure a 400 series probe from nose/midline

of the mouth to ear and then to an imaginary

line between the nipples.

(2) Mark this position on the probe with tape/

indelible pen.

(3) Insert the probe via mouth or nose up to the mark.

(4) Secure the probe to the upper lip.

(a) Connect the rectal or esophageal probe to

black cable jack.

(b) Connect black cable to probe outlet in

Blanketrol (Fig, 45.18I).

(c) Initiate induction of HT (Gradient Variable

mode)
