“…Good results were shown by the previously studied first phase of the rectilinear pulse: 273.5 μA 2 •ms/cm 4 (relative energy threshold being 1.14) [12]. Notwithstanding this, one of the important tasks for all type of biphasic pulse is to stabilize its duration (close to its optimal length of about 10 ms) irrespective of transthoracic impedance [17]. Along with this, the experimental results have shown pulse modulation to lower rather than enhance its efficacy [12] [18].…”

“… 32 , 33 On the other hand, defibrillation parameters such as energy, current, and waveform duration are key variables that determine the defibrillation efficacy. 34 , 35 , 36 , 37 Although the low-temperature environment could cause a decrease in the delivered energy in some AEDs, this reduction was much smaller than the variation caused by impedance change in the same AED and the variation between different AEDs. Therefore, the suboptimal waveform parameters themselves may have a greater impact on defibrillation efficacy than the environmental factors.…”

“…В связи с тем, что СГК боль ных находится в очень широком диапазоне (от ~25 до 180 Ом), использование укоренившегося в практике метода градации дозы разрядов по величине энергии является «нефизиологическим дескриптором» дефиб рилляции. В то же время дефибрилляция, основанная на стабильных уровнях тока, является лучшим физио логическим критерием ее дозы [22][23][24]. Таким образом, метод «токовой дефибрилляции», с одной стороны, поз воляет избегать нанесения первых неэффективных раз рядов из за выделения недостаточной энергии и, соот ветственно, тока у больных с высоким СГК.…”
