Bai Mingming still has emergency experience, and he asked Su Quan: "How is the patient's blood oxygen?"

When it comes to breathlessness, the first thing you need to pay attention to is your blood oxygen saturation.

Su Quan was anxious, and the patient's blood oxygen saturation had been hovering in %.

The oxygen saturation of normal people is generally above 98%.

Less than 94% means that the blood oxygen saturation is insufficient.

Below 70%, the patient is in a state of hypoxia.

Needless to say, what is the harm of hypoxia, it can damage organs and tissues at least and be life-threatening at worst.

It's already 70 percent.

At this time, oxygen is generally needed to increase blood oxygen saturation.

But at this moment, the patient has been put on the highest level of oxygen inhalation, the ventilator.

The patient's oxygen saturation has been kept very low, which is abnormal.

Unless, the patient's lungs, have developed a very serious problem.

But the human lungs are still very strong.

Normal human body, there are left lungs, right lungs. There are three lobes in the left lung and two lobes in the right lung. Even if three lobes are removed, a person can breathe.

Because it was a traumatic injury, before the thoracostomy drainage just now, Bai Mingming and Su Quan had already asked the patient to take a chest X-ray.

There are no signs of damage other than compression of lung tissue due to fluid accumulation.

Overall, it is a relatively minor chest trauma.

That's why the two didn't call someone outside the chest for consultation.

I thought that with thoracostomy drainage, the effusion would be cleared, the compression would disappear, the lung tissue would re-expand quickly, and with the intubation to assist breathing, the patient should soon breathe smoothly and the condition will be relieved.

But I never expected that the patient's condition did not improve at all.

Bai Mingming and Su Quan were a little panicked.

The emergency room can sometimes be like solving a crime.

All kinds of clues are placed in front of you, and you have to find the culprit, that is, the cause.

Bai Mingming has no clue now.

He was very worried that the chest X-ray had not been taken well just now, and that the patient's lungs still had problems.

He hesitated for a moment and said to Su Quan: "Or, do another chest X-ray review." ”

Su Quan nodded in agreement. He also felt that the patient still had a problem with his lungs.

Emergency chest x-ray review, soon out.

Bai Mingming and Su Quan saw that the effect of thoracostomy drainage was obvious, and the patient's originally compressed lung tissue had been re-expanded.

This would have been good news.

But the two were not happy at all.

The patient still has difficulty breathing and low blood oxygen.

At this time, Bai Mingming, who had always been sven, couldn't help but burst into a foul mouth, "TMD, this is really evil, everything is fine, but the blood oxygen can't rise." ”

Su Quan didn't speak, and he was also worried.

Cao Xin suddenly shouted at this time: "The blood oxygen is 60%." ”

Su Quan couldn't help it at this time, and said, "Let's find Team Leader Zhou." Big trouble. ”

Bai Mingming nodded weakly.

Monday and Cao Xin arrived at the rescue room.

While checking the patient's condition, he listened to Bai Mingming and Su Quan introduce the previous situation.

Judging from Su Quan's introduction on Monday, there is no problem with his and Bai Mingming's operation.

This chest injury is indeed not too serious.

A puncture and drainage should solve the problem.

Why is this happening?

Zhou Yi was also a little puzzled.

At this time, Bai Mingming handed over two chest X-rays.

On Monday, while looking at the chest X-ray, he turned on the system scan.

Before and after the operation, I saw two chest X-rays on Monday, and I was more sure that there was no problem with Bai Mingming and Su Quan's judgment and treatment, and the patient's lungs were normal.

Now it's up to you to see the results of the system-assisted check.

A few minutes later.

The system assists in giving a comprehensive inspection result.

Condition: chest tightness, difficulty breathing.

Causes: Pleural effusion that continues to ooze due to chest trauma and inadequate oxygen delivery.

Treatment has been taken: thoracentesis drainage, assisted breathing

Suggested treatment: increased oxygen.

Zhou Zhou was stunned for a moment when he saw the result.

Not enough oxygen?

I was already on a ventilator, and I didn't have enough oxygen.

Could it be that this ventilator is fake?

Monday's eyes immediately fell on the ventilator.

The machine is definitely normal.

That's what went wrong.

Zhou Sheng continued to look, and finally his eyes fell on the trachea.

In general, the intubation of the trachea is available in a variety of models to suit different populations.

There are many types, starting from the smallest trachea with a diameter of 2.5 mm for newborns and ending with an adult trachea of more than 8 mm.

Zhou Zhou's visual inspection showed that the patient was tall and big, but now Su Quan's trachea should be an 8mm trachea used by normal adults, and compared with the patient's body size, the first feeling is that this trachea is too small.

The size of the trachea definitely affects the amount of oxygen delivered.

Is this the problem?

Zhou Yi also had no experience with this.

However, the system gives that the oxygen is insufficient.

Monday can only think of this possibility.

Zhou Zhou immediately said: "Is there a bigger pipe, try to change it to a big pipe." ”

Bai Mingming and Su Quan were stunned for a moment.

The two of them asked in unison, "Is it a pipe problem?"

Zhou Zhou said: "The lungs are normal, on the ventilator, the blood oxygen is not enough, I suspect that this tube is too thin, I will try to change it first." ”

Now Monday is the authority in the emergency center.

Bai Mingming and Su Quan did not explain better.

The two immediately accepted Monday's opinion.

Su Quan found a large trachea and replaced it with the patient.

As a result, a miracle happened, and the patient's blood oxygen rose rapidly.

70%……

80%……

90%……

The last way to 96%.

Bai Mingming and Su Quan both took a deep breath.

I didn't expect that it seemed like such a serious problem, but it was because of a tube.
