Intelect® Transport 2-Channel Electrotherapy
12
OVERVIEW
Burst Frequency (Freq.)
- This is the number of bursts per second (bps). The available burst frequencies on the Intelect Transport 2-
Channel Electrotherapy unit are 20 to 100 bps. This parameter is unique to the Russian waveform.
Carrier Frequency (Freq.)
- Associated with the Interferential and Russian waveforms, Carrier Frequency is the frequency of the un-
modulated medium frequency current. The available carrier frequencies are 2,500, 4,000, and 5,000 Hz for IFC, but fixed at 2,500 Hz for
Russian and Premodulated waveforms.
CC/CV
- This is the abbreviation for Constant Current/Constant Voltage. Constant current is a stimulator capable of delivering an electric
current that flows at the same amplitude regardless of changes in tissue impedance over time. Constant voltage is a stimulator capable of
delivering a source of voltage at the same amplitude regardless of changes in tissue impedance over time. Most modern electrotherapy
units are of the constant current type because they provide a consistent, or stable level of current amplitude throughout the therapy
session, thus making it comfortable for the patient and predictable for the clinician. Keep in mind that the amount of stimulation is directly
proportional to the current.
Channel Mode
- The available channel modes are Single Channel (in which electrotherapy is distributed from one channel), Reciprocal
(where electrotherapy alternates between channels), and Co-Contract (where electrotherapy is distributed from both channels at the same
time). This parameter is unique to the Russian waveform.
Cycle Time
- Cycle Time is the alternating time which the current is "on" and "off." Using the 10/30 setting as an example, the current is on
for 10 seconds and off for 30. The available cycle times are Continuous, 5/5, 4/12, 10/10, 10/20, 10/30, and 10/50. This parameter is unique
to the Russian, Premodulated, and HVPC waveforms.
Display
- Available only on the HVPC waveform, the Display feature allows you to change the displayed Intensity parameter from Volts to
Peak Current (Amps).
Duty Cycle
- This is the ratio of the “On” time to “Total” time of the cycle, expressed as a percentage. The duty cycle describes the pulsed
modes of electric stimulation. The lower the percentage, the lower temporal average intensity. 100% is continuous electrotherapy. The
available Duty Cycles are 10, 20, 30, 40, 50%. This parameter is unique to the Russian waveform.
Frequency
- Frequency is the number of times per second a pulse will repeat itself. The unit is selectable from 10-120 pps. This parameter
is unique to the HVPC waveform.
