Can Apple Watch 7 Measure Blood Oxygen Levels?

On our wedding day, my bride insists on wearing an old, beat-up watch with the million-dollar wedding dress I buy her. I call off the wedding on the spot. She looks at me in shock. "You called off the wedding just because of a watch?" I take out the divorce agreement and tell her to sign. "Yes. Because of that watch." Everyone calls me crazy. They cannot believe I would end a ten-year relationship over something so worthless and file for divorce in front of everyone. Dad walks up and slaps me across the face. "Get on your knees, you disgrace." My mother-in-law shrieks that I have ruined her daughter's future by returning her like damaged goods. I look at the watch on her wrist, which is stopped at 3:07, and I smile. Then, I phone my assistant. "It's time. Release everything. I want a divorce."

After my fiance’s childhood friend found out I was born with a heart condition, she secretly poured a high-dose energy drink into my champagne. The moment I drank it, my heart started racing, and stabbing pain spread through my chest. In a panic, I tore open my only emergency medication, but the water I used to take it had been swapped with strong lemon water. As soon as I drank it, my face went pale. I lost all strength and collapsed to the ground. “Lemon water’s full of vitamin C. It helps with hangovers and keeps you healthy.” Charlotte Whitmore laughed so hard she nearly doubled over. With her arms crossed, she looked at my fiance, Ethan Cross, the boss of the Rolling Stones. “Ethan, your fiancee’s acting is incredible! “I’ve been a doctor for years, and I’ve never seen anyone react like this to a little champagne and lemon water.” I bit my lip until I tasted blood. The pain made my eyes sting, and I clutched Ethan’s leg. “Honey, please, call an ambulance! I can’t take it anymore…” For a moment, his expression wavered, but the guests quickly cut in. “Come on, stop pretending! Nobody dies from a bit of champagne and lemon water.” “Yeah, you’re just jealous Charlotte got promoted and didn’t want to toast to her.” Ethan’s face turned cold again. He yanked my hand off and stepped away. “Charlotte’s a doctor. You’ll be fine with her here.” I stopped begging and texted my father asking for help.

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.

On graduation day, I caught Julian—the boy who had been my shadow for twelve years—pinning another woman against the wall, kissing her hard. His hand smacked her ass before he scooped her up and carried her into the hotel. When my call interrupted him, he just hung up impatiently and texted back: "Aria, stop playing the fragile little girl with your panic attacks. I'm not your babysitter anymore." "I'm the next in line for the Valerius family. I have real business to handle. I don't have the energy to be your nanny." Then, he coldly sent me a link to some newly developed AI personal assistant app. "If you're that lonely, go chat with the AI. It's way more useful than you clinging to me every day." I stood frozen, tears streaming down my face. A suffocating wave of heartbreak and loss swallowed me whole. My parents died saving his parents—the current Don and Donna of the Valerius Family. We grew up together. He took care of me for twelve years. I always thought he loved me. I even thought we'd get married one day. But now, I was just a burden. An annoyance. Watching his back disappear into the hotel lobby, I numbly downloaded the app. "What color should I wear to the graduation party?" "Burgundy. It complements your pale skin and hugs your curves perfectly." "I want to change up my jewelry too..." "You have beautiful collarbones. You don't need anything complicated. A minimalist platinum necklace would be perfect." "Where should I go for my solo graduation trip?" "Your private account shows a love for the Mediterranean. Go to the Amalfi Coast. The sun will look good on you." "Okay. I'll listen to you." Wait. Something was wrong. Why would an AI app know about my secret Instagram account?

My heartbeat is so steady that sometimes, I don't resemble a human being at all. The fluctuations in my heart rate are very small even though I might be sleeping, suffering from a fever, or losing too much blood. When I'm 18 years old, the Ziegler family admits me into a rehabilitation center. My new home is now a temperature-controlled intensive unit located on the top floor. Oh, Aiden Ziegler doesn't love me at all. It's merely because the one and only artificial heart present in this world—and also in his chest—needs to be fine-tuned with my own heartbeat as its primary frequency. If my heartbeat is steady, he gets to live. If not, he dies. Three months ago, a nurse accidentally took off one of the monitoring pads on my chest. Five minutes later, Aiden, who was ten thousand miles away, went through a temporary crash where his heart stopped. The next day, the third-party medical company filed for bankruptcy. Everyone who was involved in this incident got banned by the medical world. Because of that incident, all of the sounds get eradicated from the top floor. Even the elevator's chimes get muted when it reaches the top floor of the rehab center. Everything changes when Aiden flies to Iropa. That's when his fiancee, Mandy Sutherland, takes over the rehab center. As she flips through my medical bill of nine figures, she sneers at me. "So, the Zieglers are basically sustaining a loser who does nothing but gasps for breath while lying in bed, huh?" After that, Mandy tears off the monitoring pads and unplugs the sync line. Then, she forces me to get on a treadmill. "That'll be a six-mile run for you. You can forget about returning to the top floor if you can't finish the run." As I grip the handrails tightly, I can feel my heart rate turning erratic for the first time ever. It feels as though my heart is about to burst out of my chest. As soon as the alarm goes off, Mandy turns it off immediately. What she doesn't know is that Aiden's artificial heart has already gone crazy, just like mine, while he's stuck in a place that's 12 time zones away.
