What is the role of external defibrillator

Summary: The external defibrillator is an emergency medical equipment, the role is to use a strong pulse current to eliminate arrhythmia, so that the heart to restore sinus rhythm. In addition to first aid methods and cardiopulmonary resuscitation, then in the first aid external defibrillator and cardiopulmonary resuscitation which first? Generally speaking, if there is a defibrillator around, there will be a defibrillator and then cardiopulmonary resuscitation (CPR), if not, then CPR and then defibrillation. What is the role of the specific external defibrillator and external defibrillator and cardiopulmonary resuscitation which first, together to the text to see it! First, what is the role of the external defibrillator

Defibrillator is a necessary emergency equipment in the operating room. Its role is to use a stronger pulse current to eliminate arrhythmia, so that the heart to restore sinus rhythm. For CPR, defibrillation is one of the very important steps. When a patient has a severe tachyarrhythmia, such as atrial flutter, supraventricular or ventricular tachycardia, it often results in varying degrees of hemodynamic impairment.

When a patient develops ventricular fibrillation, the ventricle's inability to contract as a whole can terminate the heart's ejection and circulation, which, if not resuscitated in time, often leads to death due to a prolonged lack of oxygen to the brain.

Two, external defibrillator and CPR which first

Cardiopulmonary resuscitation and defibrillation therapy is clinically two common first aid measures to save the life of the patient, then in the actual first aid, external defibrillator and CPR which first?

The order of defibrillation and cardiopulmonary resuscitation (CPR) is analyzed according to whether or not there is a defibrillator or an automatic defibrillator (AED) in the environment where the sudden death occurs, as follows:

1. Defibrillator: The defibrillator is at hand, and should be given to the patient immediately to defibrillate, and then to perform cardiopulmonary resuscitation (CPR).

2. Without a defibrillator: the patient must be given CPR first, and then asynchronous defibrillation therapy after the defibrillator arrives.

Usually, the defibrillator is placed in a position where one electrode plate is placed on the right edge of the sternum between the second rib equivalent to the right side of the sternum above the nipple, and the other electrode plate is placed on the left lobe in the midline of the fifth intercostal space equivalent to the left side of the lower left side of the nipple, and is given the asynchronous mode of defibrillation, defibrillating the energy of the unidirectional wave of 360 J, and the bi-directional wave of 200 J. The patient should be defibrillated and then immediately performed 5 cycles of CPR and CPR to determine the patient's heart rate to change. to determine whether the patient's heart rate turns negative.
