Tian Qi looked at the group of medical staff surrounding the old lady. She originally felt a little warm and curious.
After all, she had never deliberately visited this kind of scene before.
However, when she heard the sharp beeping sound and saw that the old lady, who was talking with her eyes open, almost instantly went into shock, Tian Qi instantly felt as if someone had grabbed her heart.
"Ventricular fibrillation! Doctor Ling? "Nurse Niu raised her voice again and looked at Ling Ran. At the end of the day, she had never seen Ling Ran display the corresponding ability in the Emergency Department. Therefore, she raised her voice at this time to remind other doctors.
Ling Ran did not pay attention to Nurse Niu. He first looked at the ECG monitor and confirmed the electrocardiogram. At the same time, he listened to the sound of the heart before he ordered, "Asynchronous defibrillation. One hundred and fifty joules. "
Nurse Niu secretly sighed in relief and immediately passed the defibrillator that she prepared to Ling Ran.
At the same time, the other two nurses placed the patient in a position of resuscitation and applied conductive paste. Nurse Niu turned around and selected asynchronous cardioversion on the defibrillator.
Everyone did the whole set of actions in an orderly manner.
Tian Qi looked at them and felt that they did not do it quickly, but they were so fast that it was dazzling. It was like changing tires and refueling in an F1 race.
"Charging complete."
"Give way."
Ling Ran held two large electrodes in his hands and used a little force to ensure that the skin contact was good. At the same time, he pressed the discharge button with his thumbs.
The patient trembled silently.
Ling Ran turned around and looked at the ECG monitor. He immediately said, "Cardiac compressions."
At the same time, Ling Ran turned to the patient's head and shouted, "Tracheotomy pack."
In less than a minute, Ling Ran completed the tracheal intubation at the fastest speed possible and connected a simple artificial respirator to the patient. Then, Ling Ran took over the manual compressions. He did it at a stable and fast pace while he counted.
Nurse Niu immediately followed Ling Ran's rhythm and cooperated with him to provide breathing support to the patient.
CPR in the emergency room was basically two-person CPR.
This was not only because performing chest compressions and artificial respiration at the same time could increase the survival rate, but it was also because CPR was very exhausting. On average, more than one hundred CPR per minute was needed to be effective. Therefore, two people were often needed to take turns.
However, Ling Ran did not have the intention to rotate for the time being.
In essence, cardiopulmonary resuscitation was a weakened version of Ye Ke membrane, which was artificial extracorporeal circulation. Chest compressions were to allow the heart to continue pumping blood, and mouth-to-mouth resuscitation was to allow oxygen to continue to be supplied. In this way, the process of sudden cardiac arrest, in which all the organs and brain stopped working and died, was transformed into sudden cardiac arrest, in which all the organs and brain were forced to work, to see if they could persist until the heart started beating again.
Blood and oxygen were necessary for the human body's organs and brain. In theory, CPR could provide 30% of the normal supply. If the cells were described as an army, and the logistical support was maintained at 30%, the army might have lost its combat effectiveness, but at least it would not completely collapse.
High-quality cardiopulmonary resuscitation was like maintaining logistical support in the worst-case scenario.
The strength and frequency of the chest compressions, the degree of artificial respiration, and so on played an unusually important role at this time.
30% was already an extremely low limit. If it was reduced to 25%, 20%, or 15%, it might not seem like a big change, but in fact, it might be the straw that broke the camel's back.
Ling Ran knelt on the hospital bed. He only wanted to perform CPR as high quality as possible.
Just like how Nurse Niu was not familiar with Ling Ran in the emergency room, Ling Ran was also not familiar with the nurses and doctors in the emergency room.
So, he was more willing to perform CPR himself.
Just how difficult was it to perform high-quality CPR? This could be seen just by looking at the praises given to prolonged CPR in various journals and international conferences.
Prolonged CPR meant that a strong team had to carry out high-quality CPR for a long time, and they had to be extremely lucky to have one successful case.
According to the research paper Ling Ran read, a hospital had made statistics on 190 cases of CPR in a year (the resuscitation time was longer than thirty minutes), and only seventeen cases had their own circulation restored. Among the seventeen cases, only three cases were discharged alive. Among the three cases, two were in a vegetative state, and one recovered.
Even so, the one successful case still encouraged doctors' morale. After all, this was a person who was pulled back from hell.
"Defibrillation."
Ling Ran jumped off the hospital bed and picked up the defibrillator again.
After completing the defibrillation step, Ling Ran continued to perform chest compressions.
Every thirty compressions, Ling Ran would stop for a while, and Nurse Niu would perform artificial respiration twice using a simple respirator.
His Perfect Level CPR could almost guarantee the accuracy of every compression. Even so, Ling Ran still could not guarantee that the patient would wake up.
Perfect Level CPR was not Perfect Level Resurrection.
Ling Ran could only remain calm. He counted while he tried his best to think of various plans and possibilities in his mind.
The only people who were free behind the curtains were the patient and Tian Qi.
It was Tian Qi's first time seeing such a scene.
She was a little shocked, especially by Ling Ran's focus, nervousness, calmness, and calmness.
In Tian Qi's impression, a certain uncle who was famous in the copper futures market had this kind of focus, nervousness, calmness, and calmness at the most important moment. His third wife seemed to have fallen in love with her uncle because of this. Even if her uncle earned more money in the future, she would not leave him.
However, her uncle who was famous in the futures market did not look good enough for his status. Even if he had a career, success, dreams, and victories, he could only be considered ordinary.
Ling Ran …
Tian Qi looked at Ling Ran, and she could not help but fall into a trance.
"His heart rhythm has recovered."
At some point in time, Nurse Niu's loud voice pulled Tian Qi back from her reverie.
More people surrounded the hospital bed. The doctors from the Cardiology Department also joined in, and they began to think about transferring the patient for interventional radiology.
The old lady's son and daughter were also called over. They were not far away from the curtains, and they were talked to by the doctors.
Tian Qi heard professional terms such as "acute myocardial infarction" and "acute inferior myocardial infarction". At the same time, she could also hear the old lady's children's cries of surprise.
Fortunately, the cries of surprise soon turned into heavy breathing, as if they had just survived a disaster.
"Because the resuscitation was done in time, the patient's condition is better. His autonomic heart rhythm has recovered, and his blood pressure and oxygen saturation are improving. Next, we suggest that we use interventional radiology to open up the infarcted blood vessels …"
The doctor outside the curtains introduced the situation in a voice that was neither loud nor soft. His tone was gentle, and he was comforting.
As Tian Qi listened, she shifted her attention to Ling Ran again.
After completing CPR, Ling Ran's arms were tired, and his legs were weak. But his smile was unexpectedly bright.
Tian Qi looked up at Ling Ran's face and said with a smile, "Doctor Ling, you're amazing!"
