We often see medical staff use an electric shock device to save the lives of critically ill people in life or in movies and TV dramas, that is a defibrillator.
When applied to this kind of medical equipment, the patient's life is often on the line, and the situation is very dangerous, so we can see the application of the defibrillator, which is generally used when the person is unconscious and not breathing, and rescues cardiac arrest through electric shock. of patients, racing against time against death, thus greatly improving the success rate of patients' rescue.
The heart defibrillator machine mainly shocks the patient's heart directly or indirectly through current to eliminate ventricular fibrillation and arrhythmia and restore sinus rhythm.
In general, the larger the current, the better the stimulation effect, but it will also cause damage to the patient's myocardium. Therefore, it is necessary to select an appropriate amount of current.
At present, the commonly used defibrillators mainly include two-way wave and one-way wave. The current of the one-way wave defibrillator is large, generally 360J, and the current of the two-way wave defibrillator is small, generally 120-200J.
Therefore, the damage of the bidirectional wave defibrillator is small. If the myocardial damage is more serious, the use of the defibrillator China machine may affect the recovery of myocardial function.
1. It is suitable for cardiac arrest patients. 80% of cardiac arrest patients will have ventricular fibrillation. If a defibrillator is used for electrical defibrillation, it is easier to eliminate ventricular fibrillation and restore sinus rhythm;
2. Cardiac arrest patients can use a heart defibrillator after 5 cycles of cardiopulmonary resuscitation, and early defibrillation can play a key role in the patient's resuscitation.
In order to prevent cardiac arrest, we must pay attention to prevention in our daily life, and usually pay attention to maintaining some good living habits.
We should reduce smoking and drinking, actively participate in outdoor sports, maintain a good sleep and rest, eat more vegetables and fruits, pay attention to balanced nutrition, but eat more greasy food, so as to effectively reduce the situation of cardiac arrest.
A defibrillator is composed of a modular patient monitor part, an electrical cardioverter, an electrode pad, and a battery. The electrical cardioverter, also called the defibrillator, is an important part of the implementation of electrical cardioversion.
Portable defibrillator machine is equipped with electrode pads, generally two pairs of large and small, the large one is suitable for adults, and the small one is suitable for children.
During cardiac defibrillation and cardioversion, an instantaneous high-energy pulse acts on the heart, the general duration is 4~10ms, and the electrical energy is 40~400J (joules). The equipment used for cardiac defibrillation is called heart defibrillator. Shock cardioversion is completed, i.e. defibrillation.
When patients have severe tachyarrhythmias, such as atrial flutter, atrial fibrillation, supraventricular or ventricular tachycardia, etc., they often cause different degrees of hemodynamic disorders.
Especially when the patient has ventricular fibrillation, because the ventricle has no overall contractility, the cardiac ejection and blood circulation are terminated.
If a defibrillator is used to control a certain amount of energy to flow through the heart, some arrhythmias can be eliminated, and the heart rhythm can be restored to normal, so that the above-mentioned heart disease patients can be rescued and treated.
