ACAT® 1 PLUS and KAAT II PLUS® TRIGGER MODES

PATTERN

The computer analyzes the SLOPE, HEIGHT, and WIDTH of a positively or negatively deflected QRS complex. The width of the R wave must be between 25 - 135 msec. Widened QRS complexes may not be recognized, such as bundle branch blocks. Rejection of pacer spikes is automatic.

This is the pre-set trigger mode. Good for normal QRS complex rhythms. Not the best trigger for irregular rhythms.

 

PEAK

The computer analyzes the SLOPE and HEIGHT of a positively or negatively deflected QRS complex. Rejection of pacer spikes is automatic.

 

This may be the trigger of choice for wide complex rhythms. This is the preferred trigger for HR > 140.

 

AFIB

The computer analyzes the SLOPE and HEIGHT of a positively or negatively deflected QRS complex. The operator cannot control deflation of the balloon. The balloon will automatically be deflated whenever an R wave is sensed. Rejection of pacer spikes is automatic.

This may be the trigger of choice for rhythms with varying R to R intervals.

 

V PACE

The computer uses the ventricular pacer spike (V SPIKE) as the trigger signal. Because the balloon will inflate and deflate only when a ventricular pacing spike is sensed, it is ESSENTIAL that the patient's rhythm is 100% paced if this trigger is to be used.

 

 

May be used for V or AV paced rhythms. Must be 100% paced

 

A PACE

The computer uses the atrial spike (A SPIKE) as the trigger signal. DO NOT use if the patient is AV paced.

 

May be used for 100% A paced rhythms.

 

ARTERIAL PRESSURE (AP)

The computer uses the SYSTOLIC UPSTROKE of an arterial pressure waveform as the trigger signal. This mode is available as an option for clinical situations where an ECG is unavailable or distorted.

 

Not recommended for irregular rhythms or irregular pulse pressures.

INTERNAL

The balloon inflates and deflates at a pre-set rate regardless of the patient's cardiac activity. This mode is only to be used in situations where there is NO CARDIAC OUTPUT and NO ECG (cardiac arrest, cardiopulmonary bypass) Selection of this trigger mode must be confirmed by additional keystroke. The preset rate is 80 assists per minute but can be varied in increments of 5 between 40 and 120. Reducing the assist ratio will also reduce the internal rate.
