Chapter 7: Automated Functions
Description
Several automated functions are available for use during processing with the X
TRA
system:
• Autostart function - Automatically start a cycle based on the volume of blood in the reservoir.
• Continue function - Sequentially process multiple cycles without any intervention required by
the operator.
• Last Bowl function - Automate the conclusion of the case: empty the reservoir, concentrate the
last bowl, and empty the RBC line without intervention from the operator.
• Double Volume Wash function - Double the wash volume for a single cycle.
• Better Quality Wash (BQW) function - Run multiple decelerations and accelerations of the
centrifuge during the Wash phase of a cycle.
• Better Empty function - A special Empty phase which is automatically initiated when the
system detects the first Empty phase did not completely empty the bowl.
When an automation is active, the standard execution of a protocol will change, and specific actions
will be automatically executed until the automation is deactivated.
Availability of automations depends on the selected protocol and functional context. As Table 7-1
shows, the automations described in this chapter are only available with intraoperative and
postoperative protocols.
Enabling Optional Automated Functions
Some automated functions may only be initiated by the operator if they are enabled in the Features
tab of the Configuration Mode Screen. Refer to “How to Enter the Configuration Mode” on page 8-2 for
instructions on entering the Configuration Mode Screen. For more on configuring the X
TRA
system
refer to the rest of Chapter 8: Configuring X
TRA
.
Autostart Function
The Autostart function allows the X
TRA
to automatically initiate the first Fill phase of a cycle after the
system recognizes the quantity of blood present in the reservoir by means of a weight-sensitive sensor
situated on the reservoir holder. When active, once the reservoir contains the target volume of blood,
the Autostart function will automatically start the Fill phase of the selected protocol and operating
mode without any intervention from the operator.
The Autostart function may be used in conjunction with the Continue function (refer to “Continue
Function” on page 7-3). When both the Autostart and Continue automations are active, the Autostart
function manages the start of the first cycle while the Continue function manages all subsequent starts
regardless of the blood quantity in the reservoir.
