The difference between monophasic and biphasic defibrillator

BIPHASIC

The advantages of Biphasic defibrillation:

1.Electric current waveform close to square wave, the average current will be the highest, and the defibrillation success rate will be the highest.

2. Basically no current peak, myocardial function damage will be minimum.

3.The best way of the induction to the impedance changes of the human body via thoracic ,the defibrillation success rate on the patients of high impedance is the highest.


MONOPHASIC

During clinical applications,we gradually find the defects of monophasic defibrillation technology:

1.Due to the high current peak , myocardial function will be damaged seriously;

2.Because there is no automatic adjustment function to the change of the thoracic impedance performance,defibrillation effect to the patients of high impedance is not ideal.

3.Converting atrial fibrillation ability is poor.
