Chapter 759 DC Cardioversion? Why Is It so Difficult! (Red Comet Marswand Reward Added)
Grete happily threw off the task of clinical experiments.
Let him stay up all night - oh no, let him dictate the outline, and Taling stay up all night writing the experimental plan, no problem;
Let him work hard on medical research to find a cure for a disease, no problem, that's what he loves;
There is no problem in letting him raise bacteria, penicillin, and vaccines. Even though he is a clinical major, not biology or pharmacy, he can still do it with gusto;
However, he had to go all the way to the dwarf king's court, hide in that big cave that was not hygienic at all, and measure the dwarves' heartbeats, listen to their breathing, take X-rays, and inject drugs dozens or hundreds of times a day. ?
NEVER!
This is what little doctors do! And it’s a whole group of little doctors! These complicated and trivial matters should be tasks that an attending physician can complete with a group of residents and interns!
Well now, someone finally did it. Grete hummed a song and started her daily routine:
Study magic.
[Ray Deflection], [Any Door], [Shelter], especially the most important [Arcane Eye], you must learn all of them. Of course, you must also master the various defensive magic, escape magic, and attack magic required by the teacher...
Gretel knew very clearly that the Lord of Thunder had tolerated him for a long time. Now that he is on a long trip, it's not easy to check his homework. If he still can't learn a few protective spells after returning from this trip, he may be hung up and beaten by the teacher.
The current progress is that the [Shelter] is fully proficient and the portable operating room has doubled in size;
[Biolocation] I have learned it, and now I can locate parasites, but locating bacteria needs further research;
[Any Gate] is really a bit difficult. Gretel has not studied space magic before, and he has to learn [Teleport Prediction] and [Analysis Teleport Gate] along the way.
If you want to practice it to the teacher's satisfaction before the teacher comes back, you probably don't have to hope.
"So Grete, which one do you want to pick?"
Aurora asked without raising her head while immersed in the spell list. If it is good to have a high-level tower spirit, MOSS can at least project the spell list collected by Thunder Horn and let them choose on their own.
If it is some relatively low-level spells, you can also directly communicate with the Thunder Tower through the Tower Spirit to retrieve spell models for learning...
"I think it's better to learn attack spells." Gretel shrank his neck. The teacher's task is to be proficient in at least one of each type of attack magic: ice, fire, electricity, acid, force field, and sound wave.
As a magician, even if it is a medical spell, attack magic can be used, but it cannot be used without it. If you are unlucky and need to teach an idiot a lesson, you have to have two ways to control the situation, right?
"I think you don't need to choose the fire element." Aurora complained without hesitation. Gretel nodded silently: There is pure oxygen and explosives. When he advanced to the fifth level mage, he had already pushed the power of the fireball to above the fourth level.
It is estimated that the teacher will not do anything to him if he postpones the study of fire magic for the time being. Otherwise, if he tries again with "range 200 meters, explosion radius 300 meters", he won't be so lucky to have a teacher to save him.
"I don't think you have to rush to learn the ice and acid systems." Gretel shrugged: "I think it shouldn't be difficult to stack third-level spells to fourth-level power."
For the cold ball, you can use liquid nitrogen as the casting material to increase its power; for the acid ball, you can also use aqua regia and hydrofluoric acid as the casting materials respectively to try to upgrade it.
Grete estimated that it would be possible to upgrade to one level at the third to fourth level.
"So what are you going to choose?" Aurora turned her head and looked at him with bright eyes. The colored light from the magic light screen fell on his face, making his cheeks look oddly strange:
"Force field? Sound wave? I can give you some advice about force field. Sound wave is really not good. I'm not familiar with sound wave myself. Why don't you just choose thunder and lightning? I am the most familiar with thunder and lightning! The Lord of Thunder is back. If you choose electric shock Ball will be happy!"
Grete himself also wanted to choose the lightning branch. In any case, the output intensity still needs to be improved. He never wanted to encounter that "direct current cardioversion for the first time, electric shock claws with unknown joules".
What if there happens to be a patient with ventricular fibrillation?
Extracardiac compression is really not as useful as electrical cardioversion!
Gretel is gearing up. With his previous experience in dismantling magic configurations, Aurora's enthusiastic suggestions, and Archmage Carlisle for advice, he easily learned the fourth-level [Electric Shock Ball].
But the first day Aurora saw him start practicing, she went crazy.
"Crack!"
"fail."
"Crack!"
"Failed again."
"Crack!"
"It still failed..."
"Where did you fail?!" Aurora was spinning around, her cheeks reflected like a ghost by the blue-white electric light, and the white light in her blue eyes danced:
"It's obviously very successful! The attack power and attack distance all meet the requirements! Except that the attack is too obvious and easy to be discovered by the opponent - but the electric ball flies very fast, and they can't avoid it if they find it."
...I don't care if the attack is too obvious, after all, the possibility of me personally going into battle to hit someone is still a bit low. Gretel pointed to the measuring instrument that Aurora used standing on the corner of the wall:
"The output intensity is too high and the duration is a bit too long..."
"Output intensity..." Aurora choked in her throat, clutching her chest and coughing for a long time. After finally catching his breath, he immediately lowered his voice and roared at Grete:
"Of course the output intensity must be high! This is an attack spell! An attack spell! What are you going to do if you don't increase the output intensity!"
He suddenly stopped and looked around quickly. Thank God, this is in my own mage tower, and there is no one else around. Otherwise, if the follower talks to the boss like this, once word spreads, the entire Thunder Horn will be laughed at.
Aurora took two quick breaths and continued to spray:
"Any lightning mage wants to be able to summon lightning at will, to be able to summon lightning as powerful as thunder falling from the sky. If you reduce its output intensity and shorten its duration, what are you trying to do?"
"...The teacher will definitely not agree with what you said." Grete complained back with a straight face.
The Lord of Thunder has already mastered lightning. As long as you see the docile appearance of lightning around him, you can imagine that control is definitely the right direction for the development of the lightning system.
Besides, Senior Sister Philby can already feel the electron flow, and she is probably not far away from precise control of electrons. Aurora, are you sure you don't want to go in the subtle direction?
The name Lord of Thunder made Aurora shrink back. Gretel briefly talked about the development direction of several big bosses, and then he squatted silently in the corner. It seemed that an illusory sign had been erected on his forehead:
I want to be quiet——
As for who Jingjing is, that is another topic, not very important.
Gretel continued to concentrate and practice his electric spells. DC cardioversion converts 60HZ alternating current into high-voltage direct current of 4~7kVd, and discharges it to the heart within 2~4ms, with a power of up to 360~400 joules.
What he needs to do now is to break down the tasks and try them one by one. It's not difficult to lower the power. You can use relatively low-level electric spells at most, but reducing the duration...
"2 to 4 milliseconds... 2 to 4 milliseconds..." Gretel muttered and continued practicing. He switched the fourth-level [Electric Shock Ball] to the first-level [Electric Claw] and continued to practice control desperately:
freed!
Finish!
Duration, 0.5 seconds, which is 500 milliseconds.
freed!
Finish!
Duration, 0.3 seconds.
freed!
Finish!
Duration, 0.22 seconds.
Grete thought for a while and felt that he couldn't continue practicing stupidly like this. He lowered his head to disassemble the spell model, combined the "Encyclopedia of Runes" given by the teacher and the configurations he had disassembled in his past research, and pulled out a module about duration:
Increase--
reduce--
Increase--
reduce--
After going back and forth, I drew seven or eight spell configurations and then tested again. This time, the duration has been reduced to 0.01 seconds, which is 10 milliseconds.
it works!
Add a configuration to control the duration, automatically control the spell duration, effective! Then, next, we must reduce the duration of this magic to the minimum——
Grete continued to roll up his sleeves and began to toss. After three consecutive days of testing and modification, he finally controlled the lightning casting time to within 2 milliseconds. Well, next, we have to grasp the timing of casting the spell.
Grete climbed to the top of the mage tower and set up a receiving board next to MOSS, connected to the core of the mage tower. Taking a deep breath, he told the tower spirit:
"MOSS, please release the previously stored electrocardiogram. I will release the electric claw according to the rhythm. You can help me record it. The time point of each electric claw passing will be marked on the electrocardiogram."
"Okay, boss." MOSS replied solemnly. The light curtain flew up, and the R wave, P wave, Q wave, and S wave of the electrocardiogram moved forward one wave after another according to a fixed rhythm.
Gretel stared at the electrocardiogram on the light screen, and mentally activated the spell configuration of the electric claw. With a slight movement, the magic flew out——
With a "crack" sound, the blue-white electric light gently hit the receiving board and was silently sucked in by the center of the mage tower.
On the light screen, an eye-catching red dot instantly appeared.
Grete looked over impatiently. Very good, not to say it is accurate, at least it is very wrong. If the current flows through the heart at this point in time, defibrillation is impossible, but it is very possible to make the heart rhythm more irregular...
"Come again!" That time just now, it was just my reaction that was slower! Concentrate your energy and calculate the lead time, and you might be able to succeed!
"Crack."
"Crack."
"Crack."
"Crack-"
Very good. On the electrocardiogram waveform, the red dots are scattered and completely randomly distributed. There were even two times when the ventricle was in the vulnerable period. Even if there was no ventricular fibrillation, ventricular fibrillation would occur!
"Ah - why is DC cardioversion so difficult..."
