IAB FREQUENCY
Press this key to select the ratio of augmented cardiac cycles to actual
cardiac cycles. Selections available are every beat assisted (1:1), every other
beat assisted (1:2), or every third beat assisted (1:3). The selected IAB
frequency is indicated by illuminated LED indicators. When either 1:2 or
1:3 1s selected, both the assisted and unassisted systolic and diastolic
pressures are displayed and may be printed. They are labeled accordingly.
IAB AUGMENTATION
Pressing the UP and DOWN arrow keys will adjust the time interval, from OFF
to MAX, during which drive pressure is applied to the safety disk. This
interval determines the gas volume displaced from the safety disk into the
patient balloon.
IAB FILL

used to perform the Safety Disk Leak Test by holding it pressed and turning
the power on simultaneously.

illuminated in the Standby Mode and flashes during the inflation period in
the Assist Mode. Whenever the ASSIST/STANDBY key is pressed for the
first time following system power-up, a rapid start feature will expedite the
