What makes the FRED easyport so unique?
Posted in Product Spotlight by Mat Packer.
SCHILLER’s unique Multipulse Biowave® is a wave that is pulsed at a high frequency (chopped).
The pulsed wave is made up of two phases, where the current flows in two opposite directions (biphasic) with a fixed duration of 4 ms for each phase, regardless of the patient impedance. That duration has been found to be optimal for the excitation of myocardial cells, maximising the safety and effectiveness of the defibrillation.
Because a second capacitor is used to produce the second phase (negative), the amplitude of the phase is not necessarily identical to that prevalent at the end of the first phase. Consequently, it can be defined freely so as to obtain the amplitude that is best suited to the physiological needs of the heart.
The second phase is sized optimally, and the charges accumulated during the first phase in the myocardial cells can be eliminated completely at the end of the wave. As a result of that elimination, the re-excitation of the unstable cells is prevented, and therefore all the re-entry loops are blocked. The outcome is optimised defibrillation with the least possible energy.
This is how the greatest efficacy can be derived from a biphasic defibrillation wave.
