R Series Rectilinear Biphasic Waveform Characteristics
9650-0904-01 Rev. N ZOLL R Series Operator’s Guide A–15
The R Series Rectilinear Biphasic waveform employs the same first and second phase timing,
similar first and second phase currents/voltages, and essentially the same mechanisms for
controlling defibrillation waveshape as the ZOLL M Series
®
defibrillator. The M Series and
R Series defibrillation waveforms are considered substantially equivalent.
Figures A-1 through A-21 show the Rectilinear Biphasic waveforms that are produced when
the R Series defibrillator is discharged into loads of 25, 50, 75, 100, 125, 150, and 175 ohms at
each energy setting.
The vertical axis shows the current in amperes (A); the horizontal axis shows the duration of
time in milliseconds (ms).
