Normal Operation And Pressure Adjustment; Vascular Refill Detection; Shutdown - Covidien Kendall SCD 700 Bedienungs Und Servicehandbuch

Normal Operation and Pressure Adjustment

• Verify that the corresponding garment images match the disposable garment(s) applied to the patient.
• The controller automatically begins the process of applying intermittent compression alternating between limbs
or to one if only one garment is applied.
• On successive cycles, the controller automatically adjusts its operating parameters to maintain set pressure.
• The pressure setting depends on the type of garment: 45 mmHg for Leg Sleeves; 130 mmHg for Foot Cuffs.

Vascular Refill Detection

• The Kendall SCD™ 700 series compression system incorporates Covidien's patented "Vascular Refill Detection"
method to customize the therapy for each patient's physiology. This system measures the time it takes for the
veins in the limb to refill after having been compressed by the system. The time is then used in subsequent cycles
as the time between compressions.
• Vascular Refill Detection occurs automatically and requires no operator interaction.
• The Vascular Refill Detection method is used when first powering on the System after it reaches set pressure and
every thirty minutes thereafter.
• During the entire time Vascular Refill Detection is in progress, a rotating ring symbol will display in the center of
the screen as shown below in Figure 3. This symbol is informative only. No action is required by the user dring the
Vascular Refill Detection Process.
• The method works best when the patient is still, however it will accommodate movement.
• If an error is detected during any measurement or if the compression is not within the System pressure specifica-
tions, the refill time measurement will be repeated after the next compression cycle.
• The time between compressions on the same limb will never be shorter than twenty seconds or longer than sixty
seconds.
• If both controller ports are being used, then the longer of the two measurements will be used to adjust the time
between cycles.

Shutdown

To terminate the operation, press the Power On/Standby button on the device.
