Originally, the doctor wanted to enter the operating room, but was blocked by Selena.
"You don't need to go in, we just borrow your operating room."
"How can that be done? Just now, so much blood was drained from the wounded man, it is obvious that he is bleeding internally now, we must go in and help treat the internal wound."
"No need." Selena still blocked her from entering.
Instead of letting the doctors in these small hospitals go in and watch her boss startled, it's better to let them stay outside so as not to affect the boss.
At this time, the medical equipment on the second helicopter had also arrived at the same time, and Feng Shengxuan sent the things in immediately.
Originally, he wanted to help her inside, but when he entered, he found that Chiyang'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. back out.
Before exiting, she said to Nangong Nuannuan: "I'm right at the door, if you need anything, just call me."
Nangong Nuannuan didn't respond to him, but Feng Shengxuan knew she heard it.
Nangong Nuannuan in the operating room used the internal respiration machine for Chiyang as quickly as possible. Once this kind of ventilator is used, Chi Yang does not rely on his own heart contraction to circulate blood in his body, nor does he rely on heart contraction to supply vigor to internal organs.
And the lungs no longer contract the lung lobes and supply air through the beating of the heart, but rely entirely on the ventilator and various tubes to operate 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 Chiyang, but the artificial membrane she newly researched relieved the urgent need at this moment.
When this artificial membrane was first developed, the experts in medical research at Angel Pharma said it was useless.
Because once a person's heart is damaged, the heart beats 60-100 beats per minute. Taking 60 as the lowest beating frequency in the normal value, for each beat, 70 ml of blood will be squeezed out, 60 times a minute Beating and compressing, what is lost is 4200 ml of blood. However, the total blood volume of the human body is only 4000 ml. If you lose 1500 ml, most people will die immediately. If you lose 2000 ml, you will die. Those are people with extremely strong bodies.
So that is to say, once the heart is injured, within half a minute, people will die.
But for Nangong Nuannuan, heart damage is not irreversible. Because the death of a person is not due to damage to the heart, but the loss of blood squeezed out after the damage to the heart is the root cause of human death.
As long as the blood loss can be controlled at the moment the heart is damaged, and the heart can be repaired in time, even patients with heart injuries can still survive.
This was just an idea of Nangong Nuannuan before, so she made an artificial epicardium based on the epicardium and inner membrane of the human heart. This adventitia is an extremely delicate and non-rejected internal organ membrane, which is similar to an artificial heart stent.
As long as this epicardium can be sewn properly, the heart can still have the same vitality as before it was injured.
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.
