It's not that hard to open a hospital in another world, right?

Chapter 760 Tower Spirit Electric Cardioversion Apparatus, Teacher Returns!

Gretel practiced, practiced, practiced, and in the end, only one thing was certain:

The timing of direct current cardioversion is not something he, a level 7 mage, can rely on manpower to grasp.

——The window period is too short.The normal human heart rate is between 60 and 100 beats per minute, that is, every 0.6 seconds to every 1 second.

In atrial fibrillation, the heartbeat speed can reach 150-500 beats per minute. At the fastest time, there is one heartbeat every 0.12 seconds.

During this heartbeat, the waveforms presented by the ECG are P wave, PR segment, QRS complex with the largest amplitude, ST segment and T wave, and QT interval.The discharge needs to be synchronized with the R wave. This time window may be as short as 4.8 milliseconds!

As for the response speed of the human brain and nerves, I remember the treatment in the previous life said that it is 30 milliseconds.Even if you advance to a level 7 mage, your mental power and reaction ability have been strengthened, you still can't touch this hurdle...

Gretel let out a long sigh.He tapped the crystal ball at the center of the Mage Tower with his fingers:

"MOSS, play the ECG again.——Then, at the same time as the peak of the R wave comes out, change the waveform line of the R wave to red."

"Boss, what is R wave?"

Gretel gave him instructions, which is the narrowest and highest point on the electrocardiogram. MOSS was silent for about five seconds, and immediately replied:
"Okay, boss."

The light screen flickered again.The wavy electrocardiogram moved forward regularly, and Gretel stared at the screen tightly. When every R wave crest came out, the line must be changed to red, and then changed back when the crest was over.very good……

It is said that Ta Ling's reaction speed is better than that of humans!
In the previous life, there was also a computer, a high-speed computing chip, and an automatic body surface defibrillator.Prior to this, doctors wanted to use electric shock defibrillation to save the heart, basically, it was a matter of betting on probability.

Gretel happily stood up, spread out the blank scroll, and began to copy the spell.Well, this one is from an electrocardiogram, and this one is from a modified electric claw.After copying, spread it out in front of Taling:
"MOSS, can you record these two spells?"

A beam of light fell on the spell scroll, sweeping inch by inch from the beginning to the end. Moss was flat and flat, and a brisk voice rang out:

"The entry is complete, boss."

"Hmm...can you cast an electrocardiogram spell on me?"

"As long as there is authorization from the boss."

Gretel readily granted the authorization.Then, he saw his electrocardiogram.Thump, boom, the waveform is regular and perfect, and the heart rate is 55 beats/min.

The strength of this body after a major advancement is really quite good, and even the heart rate has reached the level of an athlete!

Gretel silently gave himself a thumbs up.Then he went on to give orders to Tarling:

"MOSS, according to my electrocardiogram waveform, activate the electric claw spell every time the R wave peak appears, and hit it on the receiving board. Don't hit me! Hit the receiving board!"

"Of course, boss." MOSS is still the electronic voice without ups and downs, but the interval between each word and each word is almost doubled:
"Tower-spirit-never-will-attack-master..."

Gretel felt that if this towering had a "face" setting, it would definitely show him the displeasure on his face.

"Okay, MOSS." Gretel pretended not to hear the emotion in his voice, and ordered briskly:

"Record the time of each shock and mark it on the ECG. One, two, three, go!"

"Crack!"

"Crack!"

"Crack!"

The blue-white electric light shone on the dark receiving board.

The corners of Gretel's mouth curled up.Taling automatically releases the magic of electrocardiogram and cardioversion. This treatment mode has worked!

However, it is obviously impossible for Tarling to act as an automatic defibrillator.If the patient with ventricular fibrillation was dragged to the Mage Tower for rescue, it is estimated that he would have died on the way.

The direct current cardioverter must be made portable, preferably miniaturized!

"MOSS, let me tell you, remember." Gretel lazily ordered:

"If you want to make a mobile cardioversion facility, there are two ways to go:

One is to try to connect two magics in series and make them into one.Let the magic identify the peak of the R wave, automatically trigger the electric claw, and land on the fixed point of the patient's chest wall;

The second is to make a magic tool and record the linkage of [ECG]-[Electric Claw] into it.The center of a magic device can be a magic crystal or something else. As long as a short program of the tower spirit can be intercepted, the prop can be controlled and defibrillated automatically.

Remember it? "

"Write it down, boss." MOSS graciously sent a large stack of draft paper:
"Boss, do you want to start designing now?"

Ah... how nice to have a Taling to take care of life.Satisfied, Gretel pulled a table and sat down, and began to design new magic:
After identifying and judging the defibrillable heart rhythm, it is recommended that the user defibrillate quickly, and the functions can be added slowly.Anyway, the AED machine in the previous life was added slowly...

He bowed his head and brushed the draft on the paper, recording the ideas of the new magic.Well, the first step is to unleash the magic of the ECG;
In the second step, the user judges whether defibrillation is needed, and if necessary, activate the second magic;
The third step is to automatically detect the magic, if the R wave appears, the electric claw will be triggered...

"I'm not a programmer!"

He threw the 【Endless Ink Pen】to the side, howling loudly.This [if...then] judgment trigger method, no matter how you look at it, it looks like writing a computer program!
I'm a doctor, not a programmer... Let's talk about how to write conditional-triggered magic, and how to connect magic configurations...

Gretel tried his best to search the memory, and scrapped one scroll, two scrolls, and three scrolls, but still couldn't figure it out.He dropped the pen in frustration and leaned back on the seat:
Stop writing!
Tomorrow, go to the library in the corner of Thunder to look up books!

Hey, if only the teacher was here, the teacher could at least throw him a stack of reference books...

"MOSS... Grab a rabbit and bring it up, and the fixing board to fix the rabbit... I'm going to do animal experiments..."

Animal experiments can only be done by leaning on Ta Ling's side, which is simply too troublesome.One day, he will rebuild this mage tower and set up a sub-center in each laboratory to help him control magic!
Gretel calculated for a long time before he got the current strength that should be used for direct current cardioversion of the rabbit.Turning his head, the invisible servant was already holding the rabbit cage and waiting for a long time.The rabbit chirped and screamed, and the stench filled the cage.

Gretel: "...Moss, next time I'm calculating, can you ask the invisible servant to fix the rabbit, shave off the hair, and disinfect it? Don't even have to clean up the rabbit shit..."

"Okay, boss. Shall I do it now?"

"Forget it, let me come..."

Gretel quickly fixed the rabbit, prepared the skin, disinfected it, and cast the hypnotic magic.After thinking about it, it is better to shock directly from the chest wall instead of opening the chest as soon as it comes up.

He hung up the electrocardiogram magic on the rabbit, embedded electrodes on the chest wall, and connected direct current——

One, two, three, hit the switch!
Not good, the current is too large, it seems that the result obtained is not atrial fibrillation...

Gretel inhaled, exhaled, lowered his head and quickly calculated the approximate power, adjusted the coil, and turned it on again.Well, it should be fine this time.

Very good, atrial fibrillation!
"MOSS! That spell just now!"

Lightning fell.Gretel trembled all over, and his hair stood on end:
!!!

"...MOSS, the next time you need an electric defibrillation, remember to give a warning first, the countdown is three seconds! The electric defibrillation is about to be released, please stay away from the patient, three, two, one!"

MOSS moves too fast!Before he could let go, the electricity came off!
Fortunately, he has a full set of defenses on him all the time, mage armor, cold and heat resistance, and elemental resistance.Otherwise, the current from this electric claw fell on him, and he would be shocked!
"Okay, boss!"

Gretel took a deep breath.Looking at the rabbit again, it seems that the calculated current is still a bit off. Not only did the rabbit fail to defibrillate successfully, but its vitality became weaker...

"MOSS, grab another rabbit and come up..."

Gretel threw two healing spells to the experimental rabbit, staring at the electrocardiogram, watching it recover little by little.After a while, the door of the mage tower opened wide, and Bernard walked in quickly with two cages of rabbits, and stood quietly aside.

Gretel performed ten experiments in a row.Although the success rate of the experiment is not high, he at least proved one thing:

Use a certain intensity of current to pass through the rabbit's heart at the right time, and the heart can be restored to normal beating!

Very good, if the teacher comes back, this research should be able to hand in a good homework...

Thinking like this, Gretel completely forgot that what the Lord of Thunder required of him was to proficiently release attack magic, not to be an electric defibrillator.

"Oh, Bernard, please take the rabbits down!"

The disappointment on Bernard's face was visible to the naked eye.Gretel didn't even need to ask, he knew that he must have thought that there would be rabbits to eat today.But it's a pity that each rabbit was released with a bunch of healing skills, trying to pull it back...

Gretel continued to perfect the research with confidence, using 64 rabbits, and wrote a long paper.A few days after the thesis was finished, he received a letter from Archmage Carlisle:

"The teacher is back. Next Monday, the regular meeting will be held as usual, don't forget!"

yeah!
The teacher is finally back!
Someone can ask for advice, and there is a list of books to discuss!He has been flipping left and right in the library in the corner of Thunder these days, but he has not gained anything!
Early on Monday morning, Gretel squatted at the door of the teacher and waited.At [-]:[-] in the morning, the people attending the meeting arrived one after another. When Gretel turned his eyes, his jaw almost dropped:
"Senior Brother Baierbo, Senior Sister Philby! What did you guys do?!" Why did you look so smoky? !
"Hey, little Gretel!" The brother's big and thick palm patted Gretel's shoulder heavily:

"It's a pity you didn't go this time! The teacher led us, but we fought a big battle! ——Little Gretel, hurry up and advance!"

****
Yesterday, the closing order was 2998...

It's only two... Wow, cry...

The extra ten more are gone!snort!

　Thanks to @病人说梦话 for tipping 100 starting coins

　　Take a look at the history of the development of cardiac defibrillation.

　　...The earliest record was in 1788, and then the theory and practice continued to improve. In 1941, a defibrillator was made to perform internal defibrillation. Synchronized cardioversion was invented in 1961...

　　You guys really dare to do anything!
