Difference between Monophasic and Biphasic Defibrillator

Main Difference

Different terms have the explanation that makes them different or likes each other, but the main details that make them distinct are of utmost importance. The two getting discussed in this article are Monophasic and Biphasic Defibrillators, and they both have a close relation to each other. This article helps to find the main differences between them. Monophasic Defibrillators get defined as the type of shocks given to a human under heart treatment that includes only one vector and the sine wave pattern. On the other hand, Biphasic Defibrillators get defined as the type of shocks given to a human under heart treatment that includes at least two vectors and the cosine wave pattern.

Monophasic Defibrillators

Monophasic Defibrillators get defined as the type of shocks given to a human under heart treatment that includes only one vector and the sine wave pattern. It exists in most hospitals and becomes the common and conventional procedure. These waves may not be the most useful in working but have a benefit for places that do not have large amounts of money or patients and therefore cannot invest much. The parent process has become used for different life-threatening cardiac dysrhythmias and ventricular fibrillation. The energy passed to the system during this process gets expressed in joules and therefore one ampere of current passing through the machine of one ohm resistance in one second goes the definition. Doctors do not have the facility to adjust the impedance, and therefore a fixed amount of energy of 360 joules occurs every time and has become recommended for adult patients whereas children do not can take these shocks, therefore, another process that requires less energy are used for lower aged people. The maximum current flows because of just one vector. Therefore, the wave formed usually follows the Sine wave angle and the value increases in the beginning and then gradually reaches the original value once it becomes stable. Various devices exist in the system that helps to deliver the current, and some of them include the implantable and external defibrillator. The first one detects the irregular heart rate whereas the latter one moves the high-level values without any problems.

Biphasic Defibrillators

Biphasic Defibrillators get defined as the type of shocks given to a human under heart treatment that includes at least two vectors and the cosine wave pattern. A type waveform formed during this process where the shock gets delivered to the heart with the help of two vectors and hence gets the name. Initially, they were used in the first devices but now have become common for external defibrillators. The energy passed to the system during this process gets expressed in joules and therefore one ampere of current passing through the machine of one ohm resistance in one second takes the definition. The value of current here keeps changing per the impedance and therefore does not have a fixed value. The waveforms also have two lines that show the same nature but different levels. Both Physio-Control and Philips utilize the biphasic truncated exponential (BTE) waveform initially created for internal defibrillators, however, they use unique vitality settings with the waveform. Physio-Control uses what they term a “high energy” biphasic waveform, which they term ADAPTIV Biphasic. Consider the focus levels on figuring out how to apply the biphasic waveform in an external defibrillator. In 1999 Zoll Medical Inc created an external biphasic defibrillator. To do as such, the waveform was somewhat changed, to a rectilinear biphasic shape – with a specific end goal to diminish the resistance of current through the skin. For instance, for a 200J vitality setting, the ZOLL RBW charges the capacitor to the most extreme voltage paying little heed to patient impedance.

Key Differences

  • Monophasic Defibrillators get defined as the type of shocks given to a human under heart treatment that includes only one vector and the sine wave pattern. On the other hand, Biphasic Defibrillators get defined as the type of shocks given to a human under heart treatment that includes at least two vectors and the cosine wave pattern.
  • Monophasic becomes the type waveform formed during this process where the shock gets delivered to the heart with the help of just one vector and hence gets the name.  On the other hand, Biphasic becomes the type waveform formed during this process where the shock gets delivered to the heart with the help of two vectors and hence gets the name.
  • Both the methods have become used for different life-threatening cardiac dysrhythmias and ventricular fibrillation.
  • For Monophasic Defibrillators, the wave formed usually follows the SINE angle and the value increases in the beginning and then gradually reaches the original value once it becomes stable. On the other hand, for, Biphasic Defibrillators two distinct waves help with the identification and are not sin waves.
  • Implantable Defibrillators detects the irregular heart rate for Monophasic Defibrillators. On the other hand, External Defibrillators moves the high-level values without any problems for Biphasic Defibrillators.
