Congratulations on your purchase of the BC Biomedical Model PLA Pacer Load Adapter. The PLA works
with the BC Biomedical Defibrillator/Pacemaker Analyzer to provide a range of simulated patient loads for
transthoracic or external invasive pacemakers. A total load resistance of 50Ω, 100Ω, 300Ω, 500Ω, 600Ω,
1000Ω, or 1500Ω may be selected to meet the requirements of various pacemaker manufacturers.
The PLA includes:
•
1 protective electrode cover (black)
•
1 banana test lead (red)
•
1 adapter, 2mm female to 4mm male
•
1 adapter, 4mm female to 2mm male
CAUTION:
Discharge of high-energy defibrillator pulses through the PLA will damage the PLA load
resistors. The PLA is designed for a maximum RMS current of 50mA at any input. This is
equivalent to a rectangular current pulse of 200 mA, with a pulse width of 20 mS, and a
rate of 180 pulses per minute (3 pulses per second).
NOTE:
To calculate the RMS (the square root of the mean of the square) current in a rectangular
pulse waveform with a pulse amplitude of 0.2 A, a pulse width of 20 mS, and a period of
333 mS: The square of the amplitude is 0.2 * 0.2 = 0.04; the mean (average) of the
squared waveform over one period is 0.04 * 20/333 = 0.00240; and the square root of this
average is 0.049A.
