BTL-4000 SMART/PREMIUM – MODE D'EMPLOI I PAGE 46 DE 57
single, double, triple pulses
symmetric, alternating
0 to 500 V
the pulse is in the shape of a downward exponential curve, the slope of which
depends on the impedance of the patient (the lower the patient's impedance = the
faster the decline)
the maximum length of one pulse is limited to 50 s
double pulses – two pulses following 60 s one after the other
0.1 to 500 Hz
See Current Modulation below in this chapter.
See Channel Mode below in this section.
CV mode only
monophasic, biphasic symmetric
0 to 80 mA
0 to 100 V
the shape, pulse width, frequency and modulation are defined on the IG pulses tab
bipolar application of mid-frequency currents - rectangular biphasic pulses,
interrupted
0 to 140 mA
0 to 100 V
2,000 to 10,000 Hz
30 to 150 Hz
1 : 1 to 1 : 8
0 to 120 s
0 to 120 s
0 to 120 s
trapezoid surges, sine surges or symmetric surges
(For the parameters see Current Modulation below in this chapter.)
