A Hospital in Another World? Chapter 754: MOSS’s Cardioverter Defibrillator, Teacher’s Re

Garrett practiced tirelessly, practiced tirelessly, practiced tirelessly, and finally determined one thing:

The timing for direct current defibrillation was not sothing a 7th-level mage could master through human effort alone.

——The window of opportunity was simply too short. The normal human heart rate ranges from 60 to 100 beats per minute, which ans one beat every 0.6 to 1 second.

During atrial fibrillation, the heart rate can reach 150 to 500 beats per minute, with the fastest being one beat every 0.12 seconds.

During one heartbeat, the ECG waveform includes the P wave, PR segnt, the highest amplitude QRS complex, ST segnt, T wave, and QT interval. The discharge needs to be synchronized with the R wave, and this window could be as short as 4.8 milliseconds!

Human brain and nerve reaction speed, rembered from past treatnts, is 30 milliseconds. Even if he advanced to a 7th-level mage, with enhanced ntal and reaction abilities, he couldn’t grasp it...

Garrett sighed deeply. He tapped the crystal ball at the core of the Mage Tower:

"MOSS, play the ECG again. ——Then, change the R wave’s line to red at the peak of each R wave."

"Boss, what is the R wave?"

Garrett pointed it out, the narrowest, highest peak on the ECG. MOSS was silent for about five seconds, then imdiately replied:

"Okay, boss."

The light screen flickered again. The wavy ECG moved forward rhythmically, and as each R wave peak appeared, the line changed to red and then back after the peak. Very good, very good...

Indeed, MOSS’s reaction speed was superior to humans!

In the past, with computers and high-speed computing chips, automatic external defibrillators beca possible. Before that, using electric shock to defibrillate and save a heart was basically a gamble for doctors.

Garrett happily stood up, spread out a blank scroll, and began copying spells. Hmm, this one for the ECG, and this one for the modified electric claw. After copying, he spread them out in front of MOSS:

"MOSS, can you input these two spells?"

A beam of light fell on the spell scrolls, scanning them from top to bottom. MOSS’s flat, slightly cheerful voice imdiately sounded:

"Input complete, boss."

"Can you cast the ECG spell on ?"

"As long as I have your authorization."

Garrett readily gave the authorization. Then he saw his own ECG. Thump, thump, the waveform was regular and perfect, heart rate 55 beats per minute.

This body, after a major advancent, was indeed quite strong, even reaching an athlete’s heart rate!

Garrett silently gave himself a thumbs-up. Then he continued ordering MOSS:

"MOSS, using my ECG waveform, trigger the electric claw spell at each R wave peak, hitting the receiving plate. Don’t hit ! Hit the receiving plate!"

"Of course, boss." MOSS’s electronic voice was still monotonous, but the intervals between each word almost doubled:

"The——Tower——Spirit——will——never——attack——its master..."

Garrett felt that if MOSS had a "face" setting, it would definitely show a full face of displeasure.

"Okay, MOSS." Garrett pretended not to hear the emotion in his voice, cheerfully giving orders:

"Record the ti of each electric shock, marking it on the ECG. One, two, three, start!"

"Crack!"

"Crack!"

"Crack!"

Blue and white electric light flashed on the dark receiving plate.

Garrett’s lips curled up. The tower spirit automatically casting the ECG spell and the electric defibrillation spell—this treatnt model worked!

However, having the tower spirit serve as an automatic defibrillator was obviously impossible. Dragging a patient with ventricular fibrillation to the Mage Tower would likely result in their death before arrival. ℞Α₦ÒΒÈŝ

The defibrillator needed to be portable, preferably miniaturized!

"MOSS, I’ll dictate, you write." Garrett lazily commanded:

"To create a portable defibrillator, there are two paths:

One is to try to link the two spells, rging them into one. Let the spell recognize the R wave peak, automatically triggering the electric claw at the patient’s chest point;

The second is to create a magical device, recording the linkage of [ECG]—[electric claw]. The device’s core can be a magic crystal or sothing else, as long as it can intercept a small program from the tower spirit to control the tool and automatically defibrillate.

Got it?"

"Got it, boss." MOSS diligently handed over a stack of draft paper:

"Boss, do you want to start designing now?"

Ah... having a tower spirit to take care of daily life was wonderful. Garrett contentedly pulled up a table, sat down, and began designing the new spell:

Subsequent identification and determination of defibrillable rhythms, suggesting rapid defibrillation to the user, these functions could be added slowly. After all, the AED machines in the previous life also added functions gradually...

He bent over the paper, sketching and recording the new spell’s ideas. Hmm, first step, cast the ECG spell;

Second step, let the user determine if defibrillation is needed, if needed, trigger the second spell;

Third step, the spell automatically detects, if the R wave appears, triggers the electric claw...

"I’m not a programr!"

He threw the [Endless Ink Pen] aside, wailing loudly. This kind of [if...then] judgnt trigger thod, no matter how you looked at it, seed like writing a computer program!

I’m a doctor, not a programr... speaking of which, how to write a condition-triggered spell, how to link spell structures...

Garrett searched his mory hard, ruining one scroll, two scrolls, three scrolls, still not getting the hang of it. He threw the pen aside in frustration, leaning back in his chair:

Not writing anymore!

Tomorrow I’ll go to the Thunder Horn library to check books!

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

"MOSS... bring a rabbit up, and the fixation board for the rabbit... I need to conduct an animal experint..."

Only by staying close to the tower spirit could he conduct animal experints, which was quite troubleso. Soday, he had to remodel the Mage Tower, setting up a sub-core in every lab to help control spells!

Garrett calculated for a long ti to determine the appropriate current intensity for the rabbit’s defibrillation. Turning his head, the invisible servant was already waiting with the rabbit cage. The rabbit squeaked non-stop, filling the cage with stench.

Garrett: "…MOSS, next ti I’m calculating, please have the invisible servant fix the rabbit, shave it, and disinfect it, okay? Don’t leave the rabbit poop for to clean up..."

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

"Forget it, I’ll do it myself..."

Garrett swiftly fixed the rabbit, prepped the skin, disinfected, and cast a hypnosis spell. After thinking, it was better to start with external shocks, not opening the chest right away.

He hooked up the ECG spell to the rabbit, implanted electrodes on its chest, and connected the direct current—

One, two, three, pressed the switch!

Oh no, the current was too strong, the result wasn’t atrial fibrillation...

Garrett inhaled, exhaled, quickly recalculated the approximate current, adjusted the coil, and turned it on again. Hmm, this ti it should be fine.

Great, atrial fibrillation!

"MOSS! That spell!"

Lightning struck in response. Garrett shuddered, his hair standing on end:

!!!

"...MOSS, next ti you defibrillate, rember to warn first, count down three seconds! About to release electric defibrillation, please stay away from the patient, three, two, one!"

MOSS’s reaction was too fast! He hadn’t let go yet, and the electricity ca down!

Fortunately, he was always fully equipped with defensive gear, mage armor, cold and heat resistance, elental resistance. Otherwise, this electric claw’s current hitting him would have electrocuted him badly!

"Okay, boss!"

Garrett panted heavily. Looking at the rabbit, the calculated current still seed off, as the rabbit’s life signs grew weaker instead of recovering...

"MOSS, bring another rabbit up..."

Garrett cast two healing spells on the experintal rabbit, watching its ECG closely as it slowly recovered. Soon, the Mage Tower’s door opened, Bernard entered with two rabbit cages, standing quietly aside.

Garrett conducted ten experints in a row. Although the success rate was still low, he at least proved one thing:

Using a certain intensity of current at the right ti through the rabbit’s heart could restore the heart’s normal rhythm!

Great, if the teacher cos back, this research could make a decent assignnt...

Garrett, thinking this, completely forgot that the Lord of Thunder’s requirent was to master attack spells, not to create a defibrillator.

"Ah, Bernard, please take the rabbits away!"

Bernard’s disappointnt was visible. Garrett didn’t need to ask to know he had hoped for rabbit stew today. Unfortunately, every rabbit was healed and brought back as much as possible...

Garrett confidently perfected his research, using up 64 rabbits, and wrote a lengthy thesis. A few days after the thesis was completed, he received a ssage from Archmage Carlisle:

"Teacher is back. The regular eting will be held as usual next Monday, don’t forget!"

Yay!

Teacher is finally back!

Soone to consult, a book list to ask for! These days, flipping through the Thunder Horn library, he found nothing of

value!

Early Monday morning, Garrett waited outside the teacher’s door. By 8:30 AM, attendees arrived one after another, and Garrett’s jaw nearly dropped:

"Byerbo senior, Philby senior! What happened to you?!" How did they look so scorched?!

"Hey, little Garrett!" Senior’s big, thick hand heavily slapped Garrett’s shoulder:

"You missed out this ti! Teacher led us into a big battle! ——Little Garrett, advance quickly!"
