During this time, Cao Zhao crossed his hands on the student's chest and continued to press frantically at a rate of one hundred to one hundred and twenty times per minute.
Picking up the two electrodes of the defibrillator with glue spitted on them, Cao Dong shouted to everyone: "Get out of the way!"
It was time for defibrillation. Cao Zhao was forced to stop.
Everyone quickly gave up their seats.
The two electrode pads were immediately placed on the right side of the patient's sternum and the apex of the heart, and they discharged electricity and made sounds in a split second.
After the first blow, the cardioversion was unsuccessful. I had to prepare 200 joules for the second blow.
Some people at the scene became weak in the knees again after seeing this situation. All medical students knew what it meant if defibrillation was ineffective.
I have mentioned before that electric defibrillation is not effective for all heart attack patients, it has its indications.
In the current patient, the electrocardiogram connected to the instrument shows a rapid ventricular tachycardia heart rate, which should be effective. If it does not work, one reason may be that the energy is not large enough. The operator can increase the charging energy to 200 and try again. If the second shock still does not work, the defibrillator must re-estimate the effect and consider the consequences.

...
There was a patient who was in a ventricular electrical storm, i.e., repeated ventricular tachycardia or ventricular fibrillation within 24 hours. During the rescue period, the medical staff performed a hundred defibrillations to save his life. This is a very special case. Before performing multiple defibrillations, the medical staff must have an accurate diagnosis of the patient. For example, this patient had a typical abnormal cardiac electrical activity caused by myocardial infarction.
For patients whose causes are not clear, if defibrillation fails to convert the heart rhythm successfully, doctors need to carefully analyze the cause and make a judgment. Whether defibrillation can be given again depends on whether it is completely without side effects. Defibrillation acts directly on the heart. If it does not work, whether repeated defibrillation will cause adverse consequences on the heart is unsure.
Making choices has always been the biggest challenge facing doctors in rescuing patients.
The defibrillator is not a panacea for all indications, and death is never easy to deal with.
In the current rescue situation, doctors can only think of routine medical measures according to medical procedures, and it is safest to proceed step by step.
If defibrillation is ineffective, continue chest compressions and use cardioversion and rescue drugs at the same time.
The relevant rescue personnel ran into the pharmacy, rushed out with boxes of commonly used rescue drugs and placed them on the ground, and asked the doctor: "What medicine should I use?"
No boss responded.
What medicine should be recommended? According to clinical experience, electric defibrillation is the most effective measure to deal with the current abnormal ventricular electrical activity, with the least side effects. If drugs are used for cardioversion, the side effects of cardioversion drugs are always very large, and doctors want to use them like walking on thin ice.
Simply put, the purpose of cardioversion drugs is to restore the heart rhythm to a normal state, and one of the steps is to lower the heart rate. In clinical practice, it is often seen that when cardioversion drugs are manually injected at a snail's pace, the patient's heart rate can drop from over 100 one second to under 60 the next. This is what happens to patients with a clear cause of illness, not to mention what the result would be if such drugs were used on a patient with an unclear cause of illness.
If you use the wrong medicine, instead of saving lives, you are pushing the patient towards death.
The patient in front of him is his student, so even the boss doesn't dare to act rashly.
Consider it, and consider it very carefully.
