The top priority is to restore breathing as quickly as possible to avoid cardiac arrest.

Otherwise, judging from the bald man's current performance, it would only take three to five minutes.

Regarding the relationship between pulmonary embolism and cardiac arrest, Yu Zhiming is naturally clear.

Embolism in the main arteries of the lungs will prevent blood from being discharged from the right ventricle, which can cause acute failure of the right heart.

Large-area pulmonary embolism can also cause hypoxia in the body.

The heart will inevitably be deprived of oxygen.

Myocardial cells, like brain cells, have extremely poor oxygen tolerance. They can persist for only three to five minutes before irreversible damage occurs.

The two reasons are two-pronged. If timely and effective treatment is not obtained, cardiac arrest is a high probability.

Today's first aid measure for bald men is to restore blood circulation to the right heart and restore breathing to the lungs.

These two things, combined into one, are one thing.

Yu Zhiming suddenly felt lucky that this restaurant had purchased a first aid kit with complete supplies.

Everything he needs is there.

Yu Zhiming took out two thick puncture needles from the first aid kit, and pulled out a sterile sealed infusion hose.

He used scissors to cut out a section of blood transfusion hose about thirty centimeters long and connected the back end of the puncture needle.

The rear ends of the hose and puncture needle are tied tightly with binding wire.

After completing this simple connector, Yu Zhiming touched the bald man's chest...

Immediately afterwards, Yu Zhiming raised the needle with his hand, and a puncture needle in his hand pierced the bald man's chest...

When the Qingya woman saw this scene, she exclaimed, tightly closed her eyes and covered them with her hands.

After a while, she noticed someone tugging on her sleeve, quietly opened her eyes, and looked out through her fingers...

I saw that on the bald man's chest, two puncture needles one to twenty centimeters long had not penetrated more than half, and the infusion hose connecting them had turned blood red.

That's the color of the blood flowing rapidly inside.

The Qingya woman could still see that the infusion hose was trembling under the impact of the blood flow.

She looked at the bald man's face and was surprised to find that the cyanosis on his face was rapidly changing.

Is this okay?

The elegant woman put down her hand, looked at her daughter beside her, and smiled sheepishly.

"Nanny, were you not afraid at all just now?"

Gu Qingning rolled her eyelids like Yu Zhiming, looked at Yu Zhiming's back, and took a deep breath.

The next moment, she held the elegant woman with one hand, and with the other hand, she grabbed an elegant man with gray hair and took two steps closer to Yu Zhiming.
