Chapter 2571 [2571] Big Brother Mode


    What is the main working principle of a pacemaker?


    Sends pulses that stimte the heart muscle, causing it to contract and rx.


    When should a pacemaker fire a pulse to save a patient''s life. ording 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 stimte 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 ventricr fibrition 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 patientes back from the operation, the electrocautery is no longer used. Generally speaking, the fixed mode is not used. Because this model has obvious ws. how to say? Xie Wanying continued: "I just came to have a look and found that it is not very simr to ventricr fibrition, if it is in the rhythm to induce ventricr fibrition. 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 exnation 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 willpete with each other and eventually induce ventricr Tachycardia or ventricr fibrition 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 chestpressions on the patient, but just adjusted the pacemaker mode to deal with the rm 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 bemitted by himself and his own people.


    The patient has many instruments and many pipes. It is hard to say whether it will identally 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 urate judgments and troubleshoot problems when a dangerous situation is discovered. This is the duty of the doctor on duty.


    Dr. Yao''s usation 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.


    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 ms 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 be a big news in the hospital. What''s the big news? The twopeting pirs, who seemed to be at odds with each other, even joined forces to educate her.
