More and more developed countries are deploying defibrillators in public places, such as airports, stadiums, schools, shopping malls, office buildings, etc., and they only need to undergo simple training, whether they are on-site bystanders or emergency rescuers, etc. Both can operate the defibrillator correctly and save the patient's life.
Purpose of the defibrillator:
Defibrillator Forcing the heart to be almost completely depolarized at an instant, resulting in an instant stop of the beat, making the activity of all parts of the myocardium have the same phase, so that the autonomous sinus node may re-pac the heart and control the heart beat to return to sinus rhythm.
The difference between automatic defibrillator and semi-automatic defibrillator:
All current defibrillators on the market can automatically analyze the patient's heart rhythm. Fully automatic defibrillators refer to the direct discharge without the operator's confirmation after analyzing the heart rhythm; while semi-automatic defibrillators refer to the heart rhythm after analyzing the heart rhythm. The operator will be asked if defibrillation is needed, and if necessary, manually press the defibrillation button.
The survival rate of cardiac arrest cases outside the hospital is only 1%. If the defibrillator can be used for emergency treatment within 5 minutes of the onset of the disease, the survival rate can be greatly improved. Here are a few notes about the defibrillator Matters for reference.
1.Keep the defibrillator electrode pads clean, ensure the interval is greater than 10 cm, and keep the heart between the two electrodes.
2.In case of patient has fallen into the water or has water on body, if there is a little water, you can dry it with clean towels or clothes. If it is in water or rain, need to move to a dry place to dry before attaching the defibrillator electrode pads.
3.If the patient has more chest hair, shave the chest hair clean so that the defibrillator electrode pads can be directly attached to the patient's skin, otherwise the defibrillator electrode pads may cause burns to the patient’s skin and poor defibrillation effect, etc.
4.When the electrodes of the defibrillator are close to the expiration date, the electrodes need to be replaced as soon as possible to ensure normal use in emergency situations.
Generally, the validity period of defibrillator batteries on the market is at least 2-3 years. The machine manager should keep abreast of the machine's operating conditions, and replace the battery as soon as possible when the battery is low.
