   Improper cardiac compression is equivalent to wasting the patient\'s golden rescue time, or it may not save the patient but kill the patient.

   What are these two guys doing standing by? Dr. Lin rolled up his sleeves and looked at Dr. Jiang and Huang Zhilei dissatisfiedly.

   "Wait, Lao Lin, it\'s almost there—" Dr. Jiang grabbed him and asked him to calm down.

  Sometimes, giving first aid to a patient does not mean that the more people rush up, the better. The rescue must be done in an orderly manner, and the more anxious you are, the more you need a calm heart.

   Someone started to perform cardiac compressions on the patient before, and others had better be prepared, and then go up to replace them in order when the previous person was tired or did not perform well. Because the process of helping others is equivalent to suspending rescue, it is not necessarily good for patients whose heartbeats are quickly restored.

   Now, this is exactly what happened to Dad Liu.

   Being stopped by a colleague and saying this, Dr. Lin had to turn his head to see how Xie Wanying was pressing.

   With both hands pressed in front of the patient\'s chest, Xie Wanying\'s arms were straight like two pillars, forming the most powerful pressing force.

   Glancing at this, Dr. Lin was a little surprised. I only know that too many clinical medical students start to learn cardiac compression, and within a few seconds, their arms will change from straight to curved. Because it takes a lot of arm strength and inertial movements to be very straight.

   Again, the key to cardiac compressions is that the compression position is accurate, in the middle and lower third of the sternum. This is obviously not too difficult. What is even more difficult is that the frequency and depth of continuous cardiac compression must meet the standards, otherwise it will be difficult to achieve results.

The frequency of    is as high as 100 to 120 times per minute, as recommended by CPR guidelines.

  For adults, the pressure should be up to five centimeters deep. At the same time, the pressure should be controlled well, and the pressure should not be too strong at once, which will easily break the patient\'s ribs.

   Therefore, it is a bit difficult for medical students to achieve such standard and efficient correct actions, not to mention ordinary people. Even if you practice many times on a simulated doll, it\'s a different thing on a real person, and the feeling will be different.

   Medical students who are just entering the clinic do rescue cardiac compressions for dying patients. Most teachers do not expect medical students to do it. It is for this reason that Dr. Lin does not agree that the trainee should be the first to perform cardiac compressions.

   But looking down now, Xie Wanying pressed down enough depth each time, which can be seen from the rise and fall of the patient\'s chest.

   The frequency of Xie Wanying\'s pressing even more shows her performance as a female medical student but not the same as other medical students.

The nurse beside    couldn\'t help but count her: one, two, three, four, five, six—the number seemed to be unable to keep up with the speed she pressed.

  Fast, be fast, press hard, it is the rhythm of fighting for life with death, one hundred and twenty times per minute can only be done by winning your life.

   Even if your strength is exhausted, you can\'t stop, absolutely can\'t, just a little bit, soon, soon——

   The beep on the monitor was a straight line that symbolized the gate of death. Suddenly, it changed back to beep, beep, beep. The gate of Yama Temple was forced to close, and the heart rate returned to a waveform.

   Xie Wanying stopped the first time, and pressing again at this time is not only redundant but may also hurt the patient.

  The people around her all stared at her face.

   Huang Zhilei, who was the first to react, went to the hospital bed and took out a doctor\'s flashlight to look at Dad Liu\'s pupils, and then touched Dad Liu\'s carotid artery to measure his blood pressure.
