ENERGY LEVELS AND PATIENT IMPEDANCE
The Biphasic Truncated Exponential (BTE) waveform utilizes variable energy. The actual energy delivered will
vary with the patient’s impedance and the device will deliver a shock when impedance is between 20-180
Ohms. Energy will be delivered at three different levels referred to as ultra-low variable energy, low variable
energy, and high variable energy as shown in the above waveform tables. The accuracy of the energy for the
energy in a 50 Ohm resistor is ±15%.
