The end of the city

Donghua Third People’s Hospital.

Respiratory Unit.

Single intensive care unit in Room 703.

Du Chen lay quietly on the hospital bed, looking as if he was asleep.

Next to them, Zuo Li and Zhao Hanxue stood straight with a look of shame on their faces.

Tu Anbang glanced at Du Chen and asked Zhao Hanxue:

“Tell me about the situation.”

Zhao Hanxue took a deep breath and replied positively: “The incident happened at 9:20 yesterday night, we learned from the camera from the underwater camera that there was a problem with Du Chen’s diving, he sent a distress gesture to the boat and began to float, but in the process of floating, he gradually fell into a coma, fortunately, one of the three diving instructors we went down to find someone was nearby, just in time to save him, and after getting on the boat, he did a simple treatment and went directly to the hospital.” ”

“What did the doctor say?”

“073” “The doctor said that it was just lack of oxygen and nitrogen drunkenness, the problem was not very big, but it was best not to go diving in the near future.” ”

Tu Anbang nodded slightly.

Zuo Li blamed himself: “We shouldn’t have let him go into the water alone in the first place, otherwise there would be no accident in the monitoring!” ”

“This incident was indeed caused by your slackness.” Tu Anbang said in a deep voice.

The shame on the faces of the two became even stronger.

But soon he changed his tone and said: “Fortunately, now Du Chen is fine, everything is good to say, regarding the specific monitoring matters, the headquarters will issue a new notice to you after studying.” ”

“Do you want to continue monitoring? Obviously, the light of justice has appeared, he should not be suspicious, right? Zuo Li said suspiciously.

“That’s not good.” Tu Anbang glanced at Du Chen and replied meaningfully.

Zuo Li and Zhao Hanxue looked strange.

Running from Star Bay to Yonghua Mountain to live broadcast crime and back – this is like a fantasy.

Just then, the door of the intensive care unit was pushed open, and the attending physician and diving instructor, led by a police officer, walked in.

Tu Anbang looked at the old doctor in his fifties, stretched out his hand and said: “I am Tu Anbang, the head of the special investigation team of the provincial department, and I have some questions I want to ask you about this patient, hoping to get your professional answer.” ”

The old doctor shook back and said with a smile: “Since it involves handling the case, then if there is a question to ask directly, I promise to know everything.” ”

Tu Anbang nodded and asked solemnly: “First of all, the first one is his attending physician, who is responsible for the whole diagnosis and treatment, right?” ”

The old doctor nodded and said: “That’s right, yesterday it was almost ten o’clock in the evening, we received this patient, according to the patient’s condition at that time analysis, it should be the lack of oxygen caused by diving, so we arranged him into a hyperbaric oxygen chamber at the first time, inhaled oxygen and removed nitrogen.” ”

Tu Anbang’s thick eyebrows frowned slightly: “Can you determine the cause of his diving?” As far as I know, flying in the air can also cause hypoxia. ”

The old doctor smiled and said: “You don’t understand this, from our professional point of view, hypoxia can generally be divided into four categories: hypotonic hypoxia, blood hypoxia, circulating hypoxia and tissue hypoxia.”

Hypoxia caused by changes in air pressure and oxygen concentration can be classified as hypotonic hypoxia.

According to your statement, in the thin atmosphere or space at extreme speed, it is indeed easy to cause hypoxia, but from the analysis of his hypoxia symptoms, it is fully in line with the conditions of diving high-pressure hypoxia, especially his performance is not only hypoxia, but also detected nitrogen intoxication.

Generally, in diving activities, the cylinder carried by the diver is filled with compressed air, because if it is pure oxygen diving, staying for more than an hour under the water pressure of 30 meters will cause oxygen poisoning.

The nitrogen in the cylinder has no effect on the human body under normal air pressure, but under high pressure, nitrogen molecules will integrate into nerve cells to cause different degrees of anesthesia, so that the human body produces paralysis scene, the so-called nitrogen intoxication.

Therefore, the combination of these factors can be judged that he is hypoxia caused by deep-sea diving, and I can vouch for this conclusion with my reputation as the chief physician of the respiratory department. ”

Tu Anbang nodded and replied, “Hard work.” ”

Immediately afterwards, he asked the diving instructor on the side: “You are the Instructor Yu who took Du Chen back to the boat?” ”

“It’s me.” Coach Yu answered cautiously.

Tu Anbang continued: “Please describe the specific diving search and rescue process. ”

“We received a notice from your police asking to find Mr. Du, so I went into the water with two other companions, entered the underwater cave to search, and after reaching the middle section, we found that there were three passages, and then we searched separately, and I was deep in one of the passages. After a while, I saw Mr. Du, who had fallen into a semi-coma, and then quickly took him back, and sent him to the hospital after emergency treatment……….”

“So you met him by chance?”

“Exactly.” Speaking of this, Coach Yu was still a little afraid, “Fortunately, we went down early, if we go down for a while, I am afraid that Mr. Du will really die at the bottom of the sea.” ”

“Have you figured out the cause of this diving problem?” Tu Anbang asked.

“The problem let us find it,” the expression on Coach Yu’s face was a little embarrassed, “Afterwards, we conducted a comprehensive inspection and found that a compressed gas cylinder brought down by Mr. Du had been used, and there was less than one-third of the compressed air left in it, but the gas meter of the cylinder would habitually show the full grid, and only by shaking it could the real gas volume be displayed. ”

“Your cylinders are related to the lives of divers, and once you are sloppy and there is a major safety accident, you can’t pay that responsibility!” Tu Anbang reprimanded sharply.

Coach Yu suddenly sweated profusely, and said with shame: “We will definitely try to be cautious in the future.” ”

Tu Anbang softened his face a little and asked the attending physician:

“How long will it take for him to wake up?”

“I should wake up tomorrow,” the doctor replied, “and although he is in good health, although nitrogen intoxication is more serious, he has recovered quickly after nitrogen removal from high oxygen.” ”

Tu Anbang nodded and instructed Zhao Hanxue and Zuo Li: “You continue to stay here, this time you must ensure that there are people around him for twenty-four hours, if there is a similar accident again, I only ask you!” ”

“Understood!” Zhao Hanxue, Zuo Li immediately answered solemnly.

Tu Anbang led the team out of the ward.

Regarding whether Du Chen is the light of justice, he originally had a certain speculation, but after this trip to the hospital, the result became confusing again. _
