Helping you... Save Lives. Escalating, Low Energy Biphasic Waveform: 150J - 150J - 200J Automatically compensates for each patient's resistances SCOPE™ automatically optimizes the pulse envelope for one of the widest ranges of patient impedances - thus insuring high defibrillation efficacy. Patented Technology HeartSine has developed a unique, patent pending, biphasic defibrillation energy delivery system, called SCOPE™ or Self Compensating Output Pulse Envelope. This advanced technology energy delivery platform is available on our complete family of AED devices. Developed through extensive experimental and clinical testing the SCOPE™ system gives unrivalled performance and optimizes the opportunity for successful defibrillation. Safety SCOPE™ has built-in patient safety, and limits the current delivered at higher energies. This ensures that patients only receive the energy that can have therapeutic effect, thereby limiting the risk of damage to heart cells.

SLOPE  SCOPE™ adjusts the slope characteristics of the energy waveform by switching in capacitance changes to provide an optimal current profile. The slope of this current profile is one element that ensures maximum efficacy in defibrillation which is adjusted for each shock on each patient according to their impedance.

AMPLITUDE  SCOPE™ will also vary the amplitude of the delivered waveform to compensate for a broad range of patient impedances. This means that for a given patient impedance and energy level, the correct waveform profile is delivered for each phase of the biphasic shock.

WIDTH  Varying the pulse width for both phases of the waveform profile, allows SCOPE™ to compensate for a large patient impedance range. SCOPE™ ensures that the energy pulse is delivered efficiently and safely. Adjusting the pulse width over a 3-12 msec range ensures the major portion of its energy pulse to provide maximum therapeutic value. Back to samaritan PAD page Back to samaritan AED page
