Chapter 2571 [2571] Big Brother Mode

What is the main working principle of a pacemaker?

Sends pulses that stimulate the heart muscle, causing it to contract and relax.

When should a pacemaker fire a pulse to save a patient's life. According to the different needs of clinical patients, pacemakers have different working modes. The models that are too subdivided will not be described in detail, but only two general categories will be distinguished. One is the asynchronous mode, that is, the pacemaker directly sends fixed pulses to stimulate the ventricle or new chamber of the heart regardless of how the patient's heart beats itself, which is referred to as VOO or AOO mode. What's so good about this model?

"In surgical operations, forced pacing in an asynchronous mode is adopted, so as to avoid ventricular fibrillation caused by the pacemaker being interfered by the electrocautery." Xie Wanying said.

Simply put, the electrosurgical knife will interfere with the pacemaker's sensing signal system, so a fixed mode without the operation of the sensing signal system must be used during surgery.

After the patient comes back from the operation, the electrocautery is no longer used. Generally speaking, the fixed mode is not used. Because this model has obvious flaws. how to say? Xie Wanying continued: "I just came to have a look and found that it is not very similar to ventricular fibrillation, if it is in the rhythm to induce ventricular fibrillation. I am afraid that the pacemaker has not been adjusted from the fixed mode back to other modes. After inspection, I found that this is the case, Quickly set the pacemaker back to other working modes. So, her ECG has stabilized."

Once again, the simple explanation is: Xiaohui, the child's condition has improved, and the new heart installed has finally returned to the normal working track. If the fixed mode is used again at this time, the pacemaker cannot sense the spontaneous heart rate of the patient's heart. Once the spontaneous heart rate of the well-recovered heart exceeds the pacing rate in the fixed mode of the pacemaker, the two will compete with each other and eventually induce ventricular Tachycardia or ventricular fibrillation is life-threatening to the patient.

Everyone heard this, and finally figured out the ins and outs. Xie did not and did not need to perform chest compressions on the patient, but just adjusted the pacemaker mode to deal with the alarm crisis.

Dr. Yao turned around and talked about Dr. Han: "Didn't you switch back to another mode when you came back?"

"Adjusted." Dr. Han refused. This kind of negligence would never be committed by himself and his own people.

The patient has many instruments and many pipes. It is hard to say whether it will accidentally press the pacemaker button at any time. This kind of thing that seems to be a ghost is often encountered in clinical practice. The most important thing is to make accurate judgments and troubleshoot problems when a dangerous situation is discovered. This is the duty of the doctor on duty.

Dr. Yao's accusation that the intern is actually from start to finish is groundless.

As she said, if she thinks that the intern is not suitable for these operations, she should rush into the ward immediately to prevent the intern from operating. On the contrary, it was her fault that she did not go to the scene for the first time and carefully judge the patient's condition.

"You said she did something wrong, so you won't stop it?" Cao Zhao turned to Dr. Yao, and the little whirlpool in Mo's eyes was bottomless.

"I, I'm—" Dr. Yao didn't find an excuse, and the sweat kept falling. He couldn't say that he was inferior to a medical student.historical

Mu Yongxian said to the people in the PICU: "Go to the directors of you."

The big guys never need to quarrel with others when they talk. After the quarrel is over, the other party suddenly stretches out their hands and slams them into patties.

The students at the scene have been taught, and they have to use the boss mode to teach others.

Dr. Yao would never have imagined that one day he would become a big news in the hospital. What's the big news? The two competing pillars, who seemed to be at odds with each other, even joined forces to educate her.

Thank you for your support! ! Good night dears~
