2.3.1 Life-Stat
®
System
The Arm and Column positions the Piston and Massager Pad correctly over the patient’s sternum. It is
designed to provide a sternal deflection percentage based on the patient A-P chest diameter. Sternal
deflection is nominally set to 20% of the A-P diameter. The depth of each chest compression is easily
monitored using the markings on the Dome surrounding the Piston. The Column also serves as a
storage tank that holds sufficient Oxygen to continue to drive the Life-Stat
®
for several compressions
during an Oxygen source change.
