(5) After 1 minute, press Temp Set (Fig. 45.18D).

(6) Press the ∆/∇ (Fig. 45.18) button to set the

temperature to 33.5°C.

The status display (Fig. 45.19C) will read 33.5°C.

(7) Press Gradient Variable (Fig. 45.19H).

(8) Press ∆/∇ (Fig. 45.16) to 20°C.

(9) Press the Gradient Variable (Fig. 45.19H) again.

(10) Listen for the activation of the pump.

(11) Check that the water flow indicator (Fig.

45.18F) is rotating.

(12) Place the dry sheet or disposable cover over the

infant, to decrease convection losses and fluctuations in water temperature in blanket (Fig.

45.20).

(13) Monitor temperature displays. The Patient display (Fig. 45.19E) will show the infant’s actual

temperature.

The Water display (Fig. 45.19A) will show

the actual temperature of the circulating

water.

The Status display (Fig. 45.19C) will show

the mode of operation and set temperature.

Monitor core temperature every 15 minutes

to determine when the target temperature is

reached.

Maintain HT (Gradient Variable Mode)

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

2. Press the ∆/∇ (Fig. 45.19) button to maintain core

temperature at 33.5°C.

3. Press Gradient Variable (Fig. 45.19H).

4. Press the ∆/∇ (Fig. 45.19) button to 5°C to minimize

the temperature fluctuations between the patient and

the water in the cooling blanket.

5. Press the Gradient Variable (Fig. 45.19H) again.

6. Listen for the activation of the pump.

7. Check that the water flow indicator (Fig. 45.18F) is

rotating.

Initiate Manual Rewarming after 72 hours of HT

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

2. Press ∆ button to 0.5°C.

3. Increase 0.5°C every hour until the core temperature is

36.5°C.

4. Press Gradient Variable (Fig. 45.19H).

5. Press ∆ to 5°C to minimize the temperature fluctuations

between the patient and the water in the cooling blanket.

6. Press Gradient Variable (Fig. 45.19H).
