Chapter 2469 Consequences of Heart Damage 4

Originally, the doctor wanted to enter the operating room, but was blocked by Selena.

"You don't have to go in, we just borrow your operating room."

"How does that work? There was so much blood drained from the injured person just now. It is obvious that he is bleeding internally. We must go in and help treat the internal wound."

"No." Selena still blocked her entry.

Instead of letting the doctors in these small hospitals go in and watch her boss be surprised, it's better to let them stay outside and not affect the boss.

At this time, the medical equipment on the second helicopter had also arrived at the same time, and Feng Shengxuan immediately sent the things in.

Originally, he wanted to help her inside, but when he went in, he found that Chi Yang's chest had been cut open, and when he saw that Nangong Nuannuan had to face his beloved man like this, Feng Shengxuan remained silent. Exit came.

Before exiting, he said to Nangong Nuannuan, "I'm at the door, call me if you have anything."

Nangong Nuannuan didn't answer him, but Feng Shengxuan knew that she heard it.

In the operating room, Nangong Nuannuan put Chiyang on the recirculating ventilator as quickly as possible. Once this kind of ventilator is used, Chiyang does not rely on the contraction of his own heart to circulate the blood in the body, nor does it rely on the contraction of the heart to supply the vitality of the internal organs.

And the lungs no longer perform the contraction of the lung lobes and the supply of air through the beating of the heart, and rely entirely on the ventilator and various tubes to run everything.

After using the ventilator as quickly as possible, Nangong Nuannuan cut open Chiyang's chest without hesitation, and quickly repaired the damaged pericardium.

The heart and valves brought by Feng Shengxuan did not have much effect on Chi Yang, but the artificial membrane she had newly researched relieved the urgent need at this moment.

When the artificial membrane was first developed, the medical research experts at Angel Pharmaceuticals said it was useless.

Because once the human heart is damaged, the heart beats 60-100 times per minute, taking the lowest beating frequency among the normal values ​​of 60 as an example, each beat will squeeze out 70 ml of blood, 60 times a minute. Beating compression, the loss is 4200 ml of blood. The total blood volume in the human body is only 4,000 ml. If you lose 1,500 ml, most people will die immediately. If you lose 2,000 ml, they will die. Those are people with extremely strong bodies.

So that is to say, once the heart is injured, within half a minute, the person will die.

But for Nangong Nuannuan, heart damage is not irreversible. Because people die not because of heart damage, but because of the loss of blood squeezed out after heart damage is the fundamental cause of human death.

As long as the blood loss can be controlled at the moment when the heart is damaged, and then the heart can be repaired in time, even patients with heart damage can still survive.

This was just an idea of ​​Nangong Nuannuan before, so she made an artificial epicardial epicardium based on the outer membrane and inner membrane of the human heart. This outer membrane is an extremely delicate and non-rejectionable internal organ membrane, which is similar to an artificial heart stent.

As long as this epicardium can be sewn, the heart can still have the same vitality as before the injury.

The repair of the pericardium is actually the same as the repair of blood vessels. As long as the suture is good enough, it will definitely not affect the survival time of the patient.
