Which Hyperventilation Anime Episodes Show Realistic Symptoms?

My adopted younger sister, Marissa Payton, loves pulling pranks on others. But I'm the only one who gets hurt in her pranks. Last year, she and our older brother, James Payton, locked me up in a cold storage room. Because of that, I'm afflicted with a case of severe asthma. James apologizes to me before telling me that he'll take me cave diving just to make it up to me. Marissa tags along with us on the trip. She keeps casting me malicious glances every now and then. Feeling rather uneasy, I quickly get into the water just so I can get away from Marissa. But when I'm 65 feet deep, I feel a wave of suffocation hitting me all of a sudden. It turns out that Marissa has secretly shut off the oxygen supply. I can hear Marissa's smug laughter ringing out from the underwater communicator. "Look, Jamie! I told you that Nat would fall for it again!" James' voice is filled with affection. "Leave it to you to be smart enough to think of such a prank to play on your sister, you little imp." My face has gone blue from the suffocation. I struggle with all my might in an attempt to turn on the bailout cylinder, only to feel my hands getting slapped away from them thanks to Marissa, who has swum over to me. She then whines into the communicator, "Look at how dramatic Nat is being, Jamie! She can't stand the suffocation at all even though it's only been a few seconds!" I hear James' icy and aloof voice reverberating in my earpiece. "Just hold on a little longer. Look at how delicate you are! It hasn't been all that long, yet you already can't stand it. How humiliating. You're not even in the same league as Mari!" This time, I can only stare at James in despair as my complexion slowly goes purple. Has he forgotten what happened to me? Thanks to their prank, my lungs have already sustained irreversible damage. It's getting more and more difficult for me to breathe. Finally, my vision goes black, and I collapse in the dark bottom of the sea. This prank isn't funny at all, James. This time, I'm going to die for real.

My girlfriend's so-called guy best friend found out I had epilepsy. He deliberately spiked my drink with stimulants. The moment I drank it, my nervous system was overstimulated. My heart rate surged. My chest tightened. Then the familiar warning signs hit–blurred vision, fragmented awareness, the onset of a seizure. The next second, I lost control of my body and collapsed onto the floor. My muscles convulsed violently. My jaw locked tight. My breathing turned uneven. I struggled to pull out the emergency medication I always carried with me, trying to stop the seizure from worsening. However, just as I was about to take it, I realized the hot water in my bottle had been replaced with highly concentrated coffee. The extra caffeine intensified the neurological stimulation. My convulsions worsened. My thoughts became more chaotic. My fingers stiffened to the point where I could barely move. Aaron Stone looked down at me on the floor and laughed. "Not bad. You're pretty convincing. "I've seen plenty of seizure patients before. Never seen anyone act this well." Gasping for air, I forced myself onto my knees in front of Mia, my jaw tightening from the spasms. "Mia... call an ambulance... I'm having a seizure..." Mia frowned at my obvious condition, but there was only impatience on her face. "Enough already. "If you keep acting like this, it's honestly too much. Since when can people having seizures still talk? "Aaron's a doctor. With him here, what could possibly happen to you?" I stopped trying to explain. Because I was already entering the next stage of neurological collapse. Even speaking had become difficult. Using the last of my strength, I pulled out my phone and sent an emergency distress message.

Adrian Moretti’s adopted sister—She knew perfectly well that I suffered from severe asthma and could not be exposed to smoke or strong scents. Yet during the yacht reception, she deliberately dragged me onto the open deck, where cigars burned nonstop and the wind howled. Within seconds, my chest tightened. When I reached for my inhaler, my blood ran cold. It was empty. I collapsed against the railing, gasping violently, my lungs burning as if they were collapsing in on themselves. She crouched beside me and smiled. “You’re always so dramatic. It’s just a little smoke. You don’t need to act like you’re dying,” she said softly. “You’re too weak. You need to build some tolerance.” I looked toward Adrian, my vision already blurring. “Adrian,” I choked. “Give me my inhaler. If I don’t use it right now, I’m going to suffocate.” He frowned slightly. “Don’t you think you’re overreacting?” he said coldly. “I’ve never heard of anyone dying from a bit of smoke. She’s right—you’re always seeking attention. We finally gathered tonight, and you’re ruining it.” My heart dropped. I fumbled for my phone and called my mother. “Mom,” I sobbed, barely able to breathe. “I’m being bullied… and I can’t breathe.” My voice shook violently.

I had just been discharged from surgery for a collapsed lung when my boyfriend took me to a childhood friend’s birthday party. At the party, he yanked off my ventilator and used it to inflate party balloons. My chest seized violently, as if my lung had been torn open. Justin Miller turned to Sophie Shaw proudly and said, “See? This is so much easier than blowing them up with your mouth.” I gripped the doorframe. I was gasping as my vision blurred. “Justin, I need that to survive! I can’t breathe!” His expression darkened. “Sophie was kind enough to invite you to her birthday party. Know your place! Besides, she put in a lot of effort for this day and spent hours preparing for it. Are you really going to ruin the celebration?” I struggled to speak through the pain. “Is her surprise more important than my life?” I extended a trembling hand toward the ventilator, but Justin waved it aside. He said impatiently, “I already checked. You won’t die from holding your breath for just a moment. Don’t be so selfish!” At that moment, pain stabbed me in the chest, and I used every ounce of my strength to press the emergency call button my brother had given me.

To avoid any suspicion of favoritism, my father, Myron Bradshaw, forces me to participate in the group blood donation. The only problem is I'm severely anemic. When the nurse, Lorna Ritter, draws 100 milliliters, my vision suddenly goes dark. I've just put my hand on the needle tube, about to call for a stop, when Ms. Ritter holds my wrist down. "You're calling it quits after only 100 milliliters? All the other students are donating 400 milliliters." She glances at my bloodless face, her eyes full of disgust. "Donating blood is such an honorable thing to do. Selfish fakers like you who pretend to be sick really deserve to be penalized with a double draw." Beside me, Dad looks at me coldly and says with disappointment, "Ronnie Bradshaw, is this how I raised you? Everyone else has donated, so don't think you can be an exception. You'll draw 400 milliliters of blood today even if it kills you." I gasp for air, my heart racing so fast it feels like it's about to burst. By the third tube, my vision blurs completely, and I collapse heavily to the ground. My soul slowly rises into the air as I gaze at Dad guiltily. I'm sorry, Dad, I'm really not lying. This time, I truly can't hold on any longer.

I am a firefighter. A beam crashes onto me in the middle of a burning building. At the same time, my oxygen is about to run out. I writhe and struggle as much as I can to reach for my backup oxygen canister, only to feel my fingers brushing over a bottle of water instead. When I turn around, I see my wife, Leah Sawyer, giving the last backup oxygen canister to her new mentee, Roderick Wyndham. I begin calling out to her via a walkie-talkie. "Leah, I'm being pinned down right now, and my oxygen's running out! Where is the oxygen canister?" As Leah shields Roderick behind her, she replies impatiently, "I've already given it to Roderick. It's his first time inside a burning building, so he's frightened. Having an extra canister on him gives him a sense of security. "You're already a veteran firefighter, so you can just think up a way to resolve your situation. Don't go around wasting precious resources." I can feel thick smoke infiltrating my lungs at that moment. Feelings of asphyxiation soon overwhelm me. "My leg is broken, so I can't move at all! Without oxygen, I won't be able to hold out till I get rescued!" But Leah merely chortles in response. "Stop playing the pity card! Every time we're out on a mission, you're always the cowardly one who's terrified of dying! You have zero sense of dedication at all! I shouldn't have let you join the firefighting squad, to begin with! "What's the use of you clinging to the equipment? Giving it to the newbies is the best way of maximizing its value!" I can only smile bitterly in response. Using what's left of my strength, I switch to a public channel and begin reporting to the command center. "For the record, Captain Leah Sawyer deliberately tampered with the essential rescue equipment in order to protect Roderick Wyndham, causing me, a fellow firefighter, to be trapped in a deadly situation. "I hereby request the immediate activation of the Firefighter Emergency Evacuation Act. Also, I formally charge Leah with gross negligence and attempted homicide."
