As Wu Xiangdong kept squeezing the balloon, a large amount of high-concentration, high-flow oxygen was poured into the patient's lungs unimpeded along the endotracheal tube.

The patient's chest is also supported by this airflow, and is constantly rising and falling, undergoing gas exchange.

The oxygen in the alveoli is also intensively exchanged with the pulmonary capillaries, expelling excess carbon dioxide from the body, and the fresh pulmonary blood also flows along the circulatory system to nourish various organs in the patient's body.

"Doctor Wu, look at the patient's face quickly."

At this time, the little nurse who had been responsible for monitoring the patient's life pointed at the patient's face with a surprised look on her face.

The patient's originally bruised face and lips began to turn rosy under Wu Xiangdong's repeated air blows.

Seeing this scene, the man who had been staying by the patient's side was too excited to speak.

He held the patient's hand tightly, and his originally dull eyes were suddenly filled with light.

"Mom, can you hear me?" the man said to the patient carefully.

However, facing his son's call, the patient lying on the hospital bed seemed to have heard nothing, with no expression on his face.

When the man saw this, his heart that was about to fall suddenly rose again. He quickly asked Wu Xiangdong: "Doctor, didn't the rescue succeed? Why can't my mother wake up?"

At this time, the man became nervous again. Facing his questioning, Wu Xiangdong looked at the sad-looking man, pondered for two seconds, and said: "Don't worry, the patient's coma is caused by lack of oxygen."

"It depends on the actual time the patient is deprived of oxygen to determine when she will wake up."

After all, based on the golden time for rescue, if a patient suffers from cardiac arrest, only successful rescue within 4-6 minutes can avoid irreversible damage to the brain.

For patients currently being rescued, because epinephrine is applied promptly, the prime time for rescue only needs to be within ten minutes to ensure the patient's safety.

Thinking of this, Wu Xiangdong said to the man: "If you think about it, how long did it take the patient to get from home to the hospital?"

Facing the question, the man looked up at the time and said truthfully to Wu Xiangdong: "Maybe only four or five minutes. After all, our home is not far from the hospital, and it only takes more than three minutes to drive."

Hearing this, Wu Xiangdong nodded, his brain calculating time rapidly. From the time the patient entered the emergency room to the time of intubation and rescue in the emergency room, it only took three or four minutes.

The time it took for the patient to become completely suffocated was only a few dozen seconds. Based on this calculation, the period from when the patient was deprived of oxygen to when he started to receive oxygen did not exceed ten minutes.

"If that's the case, I guess the patient should wake up."

Before Wu Xiangdong finished speaking, the nurse on the side suddenly said: "Doctor Wu, look quickly, my aunt's eyes seem to have moved."

As soon as these words came out, the man beside the bed perked up and once again approached the patient and shouted loudly: "Mom, open your eyes and look at your son!"

"Don't sleep, Mom, get up and see me!"

As the man shouted for his unremitting efforts, this time his persistence finally paid off.

The corner of the patient's eye suddenly twitched, and the fingers that were clenched were slowly flexing and extending, as if he was groping for something.

When Wu Xiangdong saw this scene, he knew that the patient was about to wake up, just as he had just deduced.

So he said to the nurse: "Here, give me the flashlight in the rescue car. I want to check the changes in her pupils."

"Okay, Doctor Wu, wait a moment." After hearing this, the nurse rummaged through the ambulance again, and finally handed over a pen-holder-sized flashlight from the inside of the third-layer drawer.

Wu Xiangdong took the flashlight with his left hand, turned on the light, opened the patient's eyelid with one hand, and shined it.

"The pupils on both sides are 2mm, and the reaction to light is still a little slow, but compared with the no reaction just now, there is still a lot of progress."

After Wu Xiangdong checked her pupils, he immediately said to the nurse: "In this case, you can quickly inject 100ml of mannitol intravenously into her veins. I think she will wake up after the infusion."

"Really?" The nurse's expression was obviously stunned after hearing this. She didn't know that this medicine had such a magical effect.

Wu Xiangdong nodded upon seeing this and said: "Mannitol can not only diuretic and lower intracranial pressure, but also lower blood sugar and detoxify. Some patients with lumbar disc herniation can also be prescribed this medicine to relieve their condition."

"As for the patient in front of me, mannitol was used to treat her increased intracranial pressure caused by hypoxia."

Since the patient's current condition is relatively stable, Wu Xiangdong also appropriately popularized some commonly used emergency medicines to the nurses.

During this period, the nurse has also hung up the mannitol and turned the liquid flow rate to the fastest. The purpose of this is to better exert its medicinal effect.

As mannitol rapidly flowed into the patient's body, her closed eyes slowly opened, and her lungs, which originally required manual pressurization for oxygen, gradually began to breathe on their own.

"Look, the patient is awake!" The nurse immediately reported the situation to Wu Xiangdong.

"I saw it." Wu Xiangdong smiled. Although he kept talking, his eyes never left the patient.

At this time, the patient opened her eyes and stared blankly at the ceiling. As her five senses gradually recovered, she felt that her lungs were burning like fire, and her throat was so painful that she could not speak a word.

"Mom, don't be afraid. We are in the hospital now and everything is fine."

Seeing the patient's panic expression, the man immediately came over to comfort him. Only then did the patient recall the thrill just now. When he saw his child again, he shed tears unconsciously.

"Mom, don't worry, I'll always be by your side. We'll be fine."

Seeing his normally healthy mother suddenly look like this, the man felt like there was a lump in his throat and was speechless for a moment.

When Wu Xiangdong saw them looking like they were parting, he couldn't help but say: "The patient is awake now. You should be happy. Why are you crying? Your mother is not seriously ill."

As soon as these words came out, let alone the man who was blinded, even the patient lying on the hospital bed looked incredulous.

"Doctor, are you telling the truth? My mother will be fine?" Even though the man said that everything was fine when he comforted his mother, when he saw the rescue like today, he was actually frightened to death.

Facing the man's inquiry, Wu Xiangdong looked confident and said: "Your mother's reaction is a typical allergic reaction. As long as you find the source of the allergy, take precautions frequently, and prepare some anti-allergic drugs at home, you won't have any symptoms like today."

Such things."

As soon as Wu Xiangdong's words came out, they were like a sea-calming needle, completely stabilizing the man's mind.

"Doctor, thank you so much. Without you today, my mother might not be able to survive. You are the benefactor of our whole family."
