Fortunately, according to her observation, her cousin has a strong willpower and can keep his composure. As long as he can control his temporary mood swings, they won't have much impact.
Xiao Shu, who felt much better, waved his hand to his cousin: I'm fine.
Xie Wanying nodded and turned around.
The grandmother sitting on the other side was old and frail, and did not have the strong mentality of her cousin, so the impact was more serious.
"Mom, Mom!" The patient's daughter was calling her mother hard.
The old woman closed her eyes tightly, her hands and feet were trembling, as if she were about to fall headlong into the pool and drown.
"Put her on the ground." This time Xie Wanying gave completely different instructions than before.
Several people around the patient hurriedly lowered the patient to the ground.
Xie Wanying walked over and picked up the defibrillator she carried, quickly untied the patient's chest clothes and attached electrodes to the patient.
This kind of defibrillator that can be carried with you in an ambulance and left the hospital is obviously different from the defibrillator used in the hospital. It is called an AED (automated external defibrillator). Last time I went to the school with Teacher Xin to use it once to rescue a patient.
The defibrillator in the hospital requires a professional doctor to analyze the patient's electrocardiogram to determine whether the patient needs defibrillation. The doctor then personally puts two electrode pads on the patient to defibrillate.
AED is almost fully automatic. As soon as it is turned on, the machine will issue instructions. The operator only needs to follow what the machine says to defibrillate the patient when necessary. The early AED animation display was very simple and more reliable.
The indicator sound emitted by the machine and the instructions carried on the machine tell the operator where to place the electrodes on the patient's body. The machine will then read and analyze the patient's electrocardiogram and issue guidance on whether defibrillation is needed.
The completely fool-proof operation is very helpful for non-medical personnel to rescue patients.
The reason why AED is widely praised and publicized by the medical community is precisely because, as mentioned before, the chance of rescuing most patients from sudden cardiac death comes from the fact that these patients have a cardiac arrhythmia, ventricular fibrillation, when they are about to die suddenly.
In this state, what is most needed is defibrillation rather than CPR (cardiopulmonary resuscitation). If the precordial area is hammered, it will cause certain damage to the patient's sternum and ribs. Using a defibrillator is the safest and safest.
"Get out of the way." Xie Wanying is about to turn on the machine. The defibrillator may defibrillate after reading the patient's electrocardiogram data. Let everyone around the patient get out of the way in advance. It is important to keep everyone at a safe distance and take precautions.
.
Regardless of the type of defibrillator, other personnel must get out of the way when defibrillating the patient to avoid being accidentally injured by the current emitted by the defibrillator.
"Mom, Mom." The patient's daughter was pulled back a little by Lu Xin and could only shout to her mother who seemed to be unconscious.
Suddenly, the flight attendant rushed in and shouted to Xie Wanying: "What do you want to do?"
The flight attendants discovered that they were using machines. No matter what machine is used on the plane, it may have a fatal impact on the flight of the plane. It affects the lives of all flight personnel and must be stopped. This is the training and education that domestic flight attendants receive.
Xie Wanying suddenly remembered what era it was now.
Not to mention domestically, there are small-scale attempts to use AEDs on airplanes abroad, but they are widely used and have been promulgated by the health department. It will be a few years before they are installed on all airplanes. The domestic situation is even more difficult to describe. AEDs have been introduced in recent years.
Later, they are generally only equipped on ambulances in 120 emergency centers and tertiary hospitals in megacities.
